Definitely Python. Lots of libraries, dead simple syntax. Lots of code examples and reference projects. Elixir is pure functional and takes time to grasp the concepts. Go is great, with simple syntax and performant runtime, but more strict as it is statically typed. For quick coding, nothing beats Python. As you come from .net I’d consider similar approach and be considering Java with SpringBoot as it makes Java faster and much more fun to code web servers

Elixir really has a good performance for the web (and in general). Its framework Phoenix for the web is a great tool, easy to install and to use, with features for websockets (and Pub/Sub) or LiveView to write reactive and real time app with only HTML (and Elixir) so basically everything is in one place

It can take some time to learn a few things in Elixir but I really think it's worth it, and it's very easy to go distributed and concurrent with Elixir. Also it's easier to code quickly with some features like the pattern matching or some operators like the pipe or the capture one

And in the case you need it you can still connect and interface Python and Elixir pretty quickly, and now Elixir has a lot of different frameworks : web, embedded or even neural networks now

Never went far with Go but I have some trouble with its syntax, I find it a bit messy

I don't have a lot of experience with the web with Python but I don't have a good experience with the little I did

Judging your previous experience we will benefit from Golang in terms of portability and speed. If you want to go simplier use Python. If it's only scripts use Python.

Hey Vitor, You can use Node and Express JS to create a backend for your app. You can create REST APIS to connect your front end with the backend. It is a very simple and scalable solution for building backend web apps.

Rust is still in low demand. It's a great language but you'll have a hard time finding jobs. Go is the mix of both Rust and Python. Great language with modern features, fast, scalable, fun to write, and at the same time it has high demand (not as much as python).

Python on the other hand is a language that you can't go wrong with. Look around you and see what your job market prefers. If there isn't much difference to you personally, pick the one with more demand.

All of these are solid options, however considering your expertise currently, I would probably suggest Node.JS considering your past experience with JS. However Python offers a similar development environment to JS in my opinion, and Go is a good sort of intermediate between Rust and Node.JS and Python. It's fast, but not as fast as Rust, and offers a development experience that combines C-styled languages (like Rust), and Python-y languages... So: Rust for the fastest, Node for familiarity, Python for ease of development, and Go for a good middle ground. I have used all in personal projects... If you use Go, I suggest a easy to use web server framework like Fiber.

Rust is a challenging choice, but worth to be chosen. It has strong memory-safety and type-safety, this gives you no bother about those errors. However, static typing languages often slow our developing speed down in early stage. In that case, it's effective to write prototype in an easy language like Python, and rewrite it in a hard language. It's important not to be afraid to throw away first code you write.

The other answers are excellent, but I want to be a bit of a contrarian and say you should learn Rust. While the number of jobs for it are (relatively) low(er), it is certainly expanding and you'd be surprised at which companies do use Rust (Discord, for example, is starting to move away from Golang to Rust!).

But the main reason is that learning Rust itself will teach you a lot about systems design (/backend) because of its borrow checker. You can try out a lot of ideas and make a lot mistakes and the borrow checker will always be there guide you to a better solution (thereby teaching you in the process).

Also, I wouldn't underestimated how important managing memory (and memory safety) is. While Golang is great in some ways, it doesn't protect you from pushing memory leaks into production. And eventually you'll come upon a scenario where you'll have to make your Python code run faster and the optimizations you'd have to do won't look pretty (or be very Pythontic).

And Rust is freakin fast! If you have Rust, you wouldn't need any other language for the backend (or any other systems level code). Check this blog post: https://blog.discord.com/why-discord-is-switching-from-go-to-rust-a190bbca2b1f?gi=dd8bc5d669d. Discord found that even after spending months optimizing Golang code it still wasn't fast enough. But unoptimized, first-draft Rust code was (is) faster by an order of magnitude!

hi - I think this depends on how you want to provide the information to the user. If you want to build a Wordpress-plugin: PHP If you want to build your own website: Python+Django / PHP / JavaScript+Node.js As Desktop application?

for what technologies you should use, this is depend on what technology do you prefer? your should think best structuing for your code because each API vendor has different to a nother one so it's better no merege code vendores together. your code must be using SOLID principle pattern and some design pattern such as Factory Pattern

The major advantage of Go is that you can run queries in parallel. Fire off a Go thread for each vendor and each thread can check the availability of assets from a specific vendor and update the database. Go supports hundreds of threads with ease.

your decision depend on what language do you know. if you know php you can use laravel framework

Hi, I would recommend Go because of strongly-typed nature which makes a developer more productive as it is less error prone compared to the other dynamic-typed language. Go also has cron-job library(powered by goroutines) that can help with your automated tasks.

python is a good language to start for the beginner.

Python is a great language to learn as a beginner. However, Go is really easy to learn as well and has a much more powerful standard library that will allow you to build very complex and powerful applications in the future. Go is becoming a standard in Cloud computing and concurrency. Both of which are very advanced but important.

I have experience in all three languages, and you should learn python first. These are three different languages (read: tools) to solve different problems you may have. Python is a high level language you can use for writing cross-platform scripts, web servers, AI, websites (e.g. Django) and the list goes on. Python can be used for most programming tasks while being the easiest to learn of the three and probably the most productive as well.

A lot of tech companies start out with Python for their web services, but due to Pythons slow speed and the pain that comes with dynamically typed languages when the code base grows, switch to Go later on when they need to scale. Go is a systems language that thrives when used for high performance cloud/web or networking services. Go is used in performance critical networking situations such as Twitch's streaming services and Uber's geofence services. It's also very clean and simple syntax that makes it very easy to quickly understand what code does.

Python is an interpreted language and Go is a garbage collected language, but Rust is a highly performant and reliable compiled programming language without the extra baggage of runtime memory management. Rust forces you to follow coding patterns that assure memory safety. This makes Rust a perfect fit for high performance algorithms, game engines or safety-critical systems, but would be overkill for web servers or scripts on modern hardware.

I'd definitely start with Go. I know Python, Go and quite a few other languages.

Rust is not easy to learn as a beginner.

Python has way too many features to be called "easy" to learn. While it is very forgiving to beginner mistakes it feels like playing in a puddle of mud. It does not teach you clean programming at all. Unless of course you like messy.

Go on the other hand is very easy to learn. As a professional you can learn the entire language in under 2 hours. I have already given the tour of Go (https://tour.golang.org/) to complete beginners and they went through it very thoroughly and thereby knew the entire Go language in less than 5 days. While it is very easy to learn and very easy to read, it is quite strict on other things, guiding you to write clean code. For one it is a typed language and it is good to learn very early about types.

Knowing the entire language is of course not all there is to know. There is the standard library and a lot of other libraries to get to know in every language. Also one has to learn patterns in every language, get experience on how to structure code, dig deeper into the language itself to understand its inner workings, etc. That takes years in every language.

That being said, it depends very much on what you want to do with a language. If you want to go into ML and science you definitely need Python. If you want to go into cloud computing, distributed servers (which in my opinion any server should be nowadays), use Go. If you want to do systems level programming, e.g in hardware programming, use Rust.

If all you want is a gentle intro and have access to tools and libs that can help with your tasks, Python is the way to go. It's ecosystem is huge and the language is easy to pick up. However, if you are aiming to get into software industry, I'd highly recommend you also pick up another classic language like C++/C#/Java. It really helps you cement some CS & programming fundamentals and get more familiar with the concept of software design and software architecture. Not saying you cannot achieve good architecture in Python or Go, but traditionally you have more materials covering these classic OOP languages. And once you learn them, you can apply your knowledge to other languages and it helps you understand other languages faster.

Rust is probably a bad choice for starting out. It is a low level language where garbage collection is not done automatically, and has to get you thinking about all the technical aspects. It is statically typed and compiled, so it's very strict with how you code. I do love Rust though, it's a nice language. Golang is also compiled and statically typed, but it aims to be for quick development, which makes it a better choice for starting out.

Python though can be great for starting out and getting a hold on how to program. You don't need to worry about things such as types, garbage collection, or an overwhelming amount of data types. Since I'm a JavaScript fanboy I can't help but say another great popular choice to start is JavaScript 😁

If you start learning programming I'd suggest Python language. I have no experience with Go and Rust so I cannot give you advice for them.

Python has the broadest reach as it's been around the longest; rust is much more difficult for a beginner to learn; I work with Go every day and it's probably the most productive general use language.

Python is the easiest of the languages to learn, and while the slowest in production, it will teach many of the basic fundamental concepts of programming, especially if you're not going to be doing anything low level or at a system level.

Learn/start with C; don't rush after buzz words. Python is easy to learn but you would not get the underpinnings of memory and pointers, an important aspect of programming.

I agree with most of the other answers here. Python is the best choice because it is super user-friendly, has an easy syntax, and can do many complex things in relatively fewer lines.

While Rust is a more recent and a great language nonetheless, it is slightly more complicated as it involves compiling and the syntax isn't so great.

And Go is the not a great choice either. While it has a decent syntax, keep in mind that Go won't be of much use unless you plan on working in Google. Even if you want to learn it, you can do so later.

I hope this helped you in making your decision, and welcome to the world of programming! I hope you enjoy.

Go and Python are going to be much easier to learn than Rust. The memory management for Rust is pretty hard to wrap your head around when you are first learning how to do basic things with the language. Get familiar with programming first, then learn Rust.

Study, machine learning = Python | High performance computing, safety-oriented programming = Rust | Backend, feel productive with less runtime performance drawback = Go

I'd choose python because with a good knowledge of python and it's libraries, you could do literally anything. Also it has a relatively simple structure, so it won't be tough for a beginner.

Later on if you wish to learn Rust and Go, please do by all means.

Python, because its the easiest to learn as a beginer. Its often called "English without grammar" because its terms and writing style is quite similar to English. Python also has a diverse range of applications like Web App, Desktop App, Data Science etc

Python is a great language to start programming with, there is an awesome python course on coursera by Dr. Charles Severance called Programming for everybody, check it out :)

Python is the best programming language for starting out as it is quite easy to learn, but it also is very powerful and you can do plenty with it. It will be useful for a long time. Python is my recommendation.

Instead of having the user copy and paste the CSS directly, have them copy and paste the HTML that will include an external CSS file generated and hosted by your application. This will allow you to control when the stylesheet is updated as well as control privileges on who can request the file. Additionally, using a CDN service (e.g. Cloudflare) will allow you to cache the static assets being requested reducing overall server load.

When your server (and optionally CDN) no longer are serving the file, consider the link expired. Unique URLs can be generated using a multitude of methods but maybe consider if there is any benefit to the users if it follows the scheme: yourdomain.com/USERNAME/CUSTOM_NAME.css rather than something like: yourdomain.com/style/SOME-UNIQUE-HASH-1234.css

The best way, as usual, is a "it depends".

Still I would go to something as simple as storing the expire date+the generated css and other metadata in a table. If a user tries to access something that is expired than he's redirected to a specific page. Periodically (like once a day), a janitor process deletes the old data.

It depends.

From times to times I asked or was asked that same question. Technology aside, it's important to consider the skills and expertise that the dev team has. Whether you use language A,B or C or framework X,Y and Z, if your team has a strong background and experience with something make it count too.

I would recommend Go simply because as you mentioned, it's super light. No need to bring in the whole .NET suite to get a simple REST API up and running. Even if your API is a bit complex, Go should be able to handle it.

I started out with C# and .NET and I loved it. In my opinion, it was the perfect way to start learning the fundamentals of software development however I always felt like I was at a disadvantage when I was doing .NET development. Granted, .NET Core is now open-source and cross-platform, but I moved to Node.js simply because it is incredibly popular. I never thought I'd learn to love JavaScript it the way I did with C#, but I learned to love it pretty quickly, especially once I started using TypeScript. You get all of the benefits of C# and JavaScript all in one. If you've built a REST API with Python/Flask/Django, you'll be able to learn Node.js/Express/TypeScript well enough to migrate your API very fast and it's incredibly easy to host for free on any number of services.

I'm new to Go, I've got very little experience but the 'feel' of Go, isn't like Python in my opinion. Go has a pretty steep learning curve, much steeper than C# in my opinion. So if you are willing to consider Node/Express/TypeScript, I think you may really like it. If you're picking between Go and C#, I'd go for C# as of today, but once I am more comfortable with Go (which I anticipate being a slow process) I may change my mind.

At this moment in time, in late 2020- Node/Express/TypeScript feels like the obvious choice to me as a former C# developer.

The best language for you is the one that you know best!

Its a bit of a guess, but from your question and the difficulties you have with Python it seems to me the problem you describe is the manifestation of a bad design/architecture/code quality. These are not the problems of a language itself!

The experience you gained over the past years with your current programming language will outmatch any benefits of another language that you start from zero.

Because in the end of the day languages aren't all that different when it comes to fullfil the same task, it's more the tools, framework and ecosystem for a particular problem that make a difference.

I worked with Java, C#, Go and recently in Phyton, and I would choose Phyton over Go for WebApps, even I like compiled languages more. Go is a very simple language, I would even say maybe too simple. I can't stand all those go boilerplate if err checks, the broken filesystem, the date/time mess and many more things that aren't actually relevant for business application at all. Go has its advantages but not for WebApps.

Keep the lang and improve your skills and architecture you will benifit more from it than from a new language.

I recommend Go for backend. It's younger than C# doesn't mean it's not mature. It's already mature enough to be run on production. You can see there are already many companies in the world adopting Go as their backend business logic or tooling. I can name a few like Github, Shopify, uber, twitch, and many more. It's easier learning curve, low entry barrier, better performance than C#, better memory consumption than C#, since there's no VM/runtime needed. It's suitable for large scale system and large codebase for readibility and long maintainability. It's simpler than C# since no class, inheritance(this can cause hard to maintain software), exception, etc. You can still implement OO way in Go without those feature. Simple file structure, only main files and package files. It compiles to single binary and easy to deploy and work around it, unlike C# who compiled to IL and you need to wrap all those IL files to be run inside separated web server(even .Net/.Net Core platform provide built-in web server). For libs, don't worry, there are many open source libs you will found on Github and already adopted by many companies. Go is employed in personal, startup, even corporate level.

I suggest Go because it has a simple and clean ecosystem. The language is simple. You don’t need complex configs or installs either. You’ll be up and running very quickly. It doesn’t have as much as .NET but its standard library is more than sufficient for RESTful APIs. Concurrency is much, much easier too.

C# I’d definitely recommend later on. The .NET framework, especially core, is extremely powerful and there’s little you can’t build with it. Go won’t take you long to be productive with.

I have some systems on production using both languages. I tend to use golang if the API is small or medium size, but if I am going to build a large system definitively I use c#(asp netcore).

If you want to stick with python you may want to consider Fastapi. It uses Pydantic to give you strongly typed models and validation. It generates openapi docs for you out of the box. They have good documentation as well and they claim it is really fast.

I would recommend C#, particularly Simplify.Web web-framework. C# is easy to start with (especially .NET Core). Simplify.Web is also easy to start with, no extra setup required for simple API, but on the other hand you have power of C# and full control over your API with ability to extend.

The database your are going to connect and the needed libraries could decide. Because both are awesome languages.

Currently, I have decided to use Python and JavaScript (especially React and Node.js) for any of my projects. Well, I have used Python with Django for a lot of things, and I would certainly recommend Django to anyone, due to its high secure authentication and authorization inbuilt system, a ready to use admin platform, template tags, and many more. Well, I guess that you would like to use Python to create the backend of your application, an API, and React Native for the frontend. Python and JavaScript (React) are on the trend these days and have a huge community, so there are many resources, tutorials, great documentation. I have not really heard anyone using Flutter and Go for applications these days, so I would not recommend it to you, it would make your life much more difficult.

Hope that helps, and good luck with your project!

I'm typically agnostic when it comes to picking languages. Whatever gets the job done, but, in this case, to figure out what's involved with what you want to do, it's going to be much more than just picking programming languages for your client and backend interfaces.

So, I'm recommending you use Flutter+Firebase as a way to figure out what you need to get done. It supports both iOS and Android out of the box, introduces you to a bunch of components you will need to think about in the future (whether you stick with Firebase or not), and the key here, is that there are tons of articles, youtube videos, and other courses you can take to pick it up pretty quickly. You could even clone an Instagram knockoff from github. Guess what else, it's all free. You might not need to worry as much about the backend since there are client libraries for Flutter/Dart for Firebase.

Some might have different opinions, and like I said, I'm usually agnostic, but in this case, you have a lot to consider. Where are you going to store the data? Are people going to need to login? Will there but customized settings the will save even if I close the app? Yeah, that's just a few questions.

Those are just a few. Lots to consider, so if you want to get something in your hand as soon as possible, try a search for flutter + firebase + chat + Instagram or something like that and have a look.

If this is for learning about how to design the system, then pick the tools are you are confortable with.

Often times, I get stuck picking the tools (and trying to learn about them) vs actually trying to design the system itself.

If you are familiar with React (check out Expo) and Django then I would recommend going with that.

For deploying your backend, I would go with a provider like https://zeit.co/ that automates a whole bunch of deployment steps with their cli tools that you might have to do with AWS.

The above listed tools will do the job, you just need to figure out your architecture(e.g models). How they will all connect. Then you can use a tool you are comfortable with to implement them.

What you need to take a look at is Apache OpenMeetings. It already does what you want, it is open source and well documented and only requires that you design the UI and plumbing required to serve you application.

Let's select right tool you feel you are good at. And selecting tools are used by large community to solve your stuck if encounter

I've worked with all three of these languages and also with Java developers converting to these languages and far and away Go is the easier one to convert to. With the improved cold-start times and the ease of conversion for a Java developer, it is a no-brainer for me.

The hardest part of the conversion though is going to be the lack of traditional Classes so you have to be mindful of that, but Go Structs and interfaces tend to make up for what is lost there.

Full Disclosure: I'm a 95% Go convert (from Python) at this point in time.

Although I am primarily a Javascript developer myself, I used Go to build AWS lambda in a similar scenario to yours. AWS libraries felt better integrated on the Go side, I believe due to the language itself (e.g. how JSON objects are handled in go). Besides that performance of Go is much superior. But on the cons side; community is far smaller around Go, compared to Javascript. That is easy notice if you look at repos of community-maintained libraries for Go. That can feel a bit unreliable.

Go would provide the easiest transition for Java programmers -- its IDE/tooling is second to none (just install Goland) and the deploy/distribution story is extremely clean and lends itself to work well in lambda: single, static binaries with quick startup. No need to set up a full environment or package dependencies on your lambda AMIs, just copy a file.

If you want to prioritise language familiarity, JavaScript is more like Java than the other choices; and it can be optimised to run very fast. However if you need really fast cold-start times, you can't beat Go since it's compiled. There are other things to consider, such as the massive amount of community packages and help/documentation in the JavaScript ecosystem. Go is newer but seems to be quite popular if you need something that runs fast in a single binary.

I was initially going to suggest JavaScript due to the smaller size needs of AWS Lambdas code and the larger range of libraries and community available (and to avoid Python for this). But I have to agree with the recommendations and rationale of @ayildirim above and I think you should choose any reasonable language that is low-overhead, fast startup, and best supported by AWS Lambda, and that is probably Go. I don't think you are likely to go wrong with that, while you can potentially with the others.

So I'd agree, on the strength of AWS Lambda support and the solid performance of Go, it seems like your best choice here for Lambdas (and I'm going to need to consider that myself going forward... pardon the pun).

I've picked Node.js here but honestly it's a toss up between that and Go around this. It really depends on your background and skillset around "get something going fast" for one of these languages. Based on not knowing that I've suggested Node because it can be easier to prototype quickly and built right is performant enough. The scaffolding provided around Node.js services (Koa, Restify, NestJS) means you can get up and running pretty easily. It's important to note that the tooling surrounding this is good also, such as tracing, metrics et al (important when you're building production ready services).

You'll get more scalability and perf from go, but balancing them out I would say that you'll get pretty far with a well built Node.JS service (our entire site with over 1.5k requests/m scales easily and holds it's own with 4 pods in production.

Without knowing the scale you are building for and the systems you are using around it it's hard to say for certain this is the right route.
