Knex.js vs MongoDB: What are the differences?
Knex.js: SQL query builder for Postgres, MySQL, MariaDB, SQLite3, and Oracle. Knex.js is a "batteries included" SQL query builder for Postgres, MySQL, MariaDB, SQLite3, and Oracle designed to be flexible, portable, and fun to use. It features both traditional node style callbacks as well as a promise interface for cleaner async flow control, a stream interface, full featured query and schema builders, transaction support (with savepoints), connection pooling and standardized responses between different query clients and dialects; MongoDB: The database for giant ideas. MongoDB stores data in JSON-like documents that can vary in structure, offering a dynamic, flexible schema. MongoDB was also designed for high availability and scalability, with built-in replication and auto-sharding.
Knex.js can be classified as a tool in the "Database Tools" category, while MongoDB is grouped under "Databases".
"Write once and then connect to almost any sql engine" is the primary reason why developers consider Knex.js over the competitors, whereas "Document-oriented storage" was stated as the key factor in picking MongoDB.
Knex.js and MongoDB are both open source tools. It seems that MongoDB with 16.3K GitHub stars and 4.1K forks on GitHub has more adoption than Knex.js with 9.91K GitHub stars and 1.24K GitHub forks.
According to the StackShare community, MongoDB has a broader approval, being mentioned in 2189 company stacks & 2218 developers stacks; compared to Knex.js, which is listed in 10 company stacks and 9 developer stacks.
