JSON Server vs MongoDB: What are the differences?

Introduction

JSON Server and MongoDB are both technologies that are widely used in web development. While they both have similarities in that they are used for managing data, there are also key differences between the two. In this article, we will explore the main differences between JSON Server and MongoDB.

1. Storage:

JSON Server is a simple database that stores data in JSON format. It is typically used for prototyping or mocking APIs. On the other hand, MongoDB is a NoSQL database that uses a document-oriented data model. It stores data in a flexible, JSON-like format called BSON.

2. Scalability:

JSON Server is not designed to handle large amounts of data or high traffic loads. It is more suitable for small-scale projects or development environments. MongoDB, on the other hand, is built for scalability and can handle large amounts of data and high traffic loads. It can be easily scaled horizontally by adding more servers to distribute the load.

3. Querying Language:

JSON Server uses a simple RESTful API to query and manipulate data. It supports basic CRUD operations (Create, Read, Update, Delete). MongoDB, on the other hand, uses a powerful query language called MongoDB Query Language (MQL). MQL allows for advanced querying capabilities such as complex filtering, aggregation, and indexing.

4. Schema:

JSON Server does not enforce a strict schema. It allows for flexible data structures and does not require predefined schemas or migrations. This makes it easy to work with during development but may lead to data inconsistency in production. MongoDB, on the other hand, supports dynamic schemas. It allows for the definition of schemas and provides validation rules for data integrity.

5. Transactions:

JSON Server does not natively support transactions. Each request is independent and changes are immediately persisted. MongoDB, on the other hand, supports ACID (Atomicity, Consistency, Isolation, Durability) transactions. Transactions allow for multiple operations to be executed as a single unit of work, ensuring data integrity.

6. Community Support:

JSON Server has a smaller community compared to MongoDB. It is a lightweight tool that is primarily used for development purposes. MongoDB, on the other hand, has a large and active community. It is a matured database technology with extensive documentation, tutorials, and community support.

In Summary, JSON Server and MongoDB differ in terms of storage, scalability, querying language, schema, transactions, and community support.
