  • The SDK is community maintained and has excellent documentation.

For example, you can define schemas for your collections, validate inserted data, and easily query MongoDB using Mongoose helper methods instead of raw operations.

Sequelize

Sequelize is a powerful ORM for working with major relational databases:

  • Supports PostgreSQL, MySQL, SQLite, and MSSQL databases.
  • Allows defining models that map to database tables.
  • Includes an expressive query API with operators, functions, sub-queries, and more.
  • Can define associations between models to handle relations.
  • Active community providing third-party plugins and integration resources.

You can use Sequelize to simplify interacting with relational databases like Postgres or MySQL when building Node.js apps, handling object-relational mapping, associations, querying, etc.

Authentication & Security SDKs

For authentication, authorization, and security needs, SDKs like Passport.js and JWT make implementation straightforward.

  • Passport - Middleware for authenticating requests and supporting protocols like OAuth and OpenID.
  • JWT - Encode and decode JSON Web Tokens for securely transmitting information.
  • bcrypt - A password hashing library used for securely storing user passwords.
  • Helmet - Express middleware for setting security headers like CSP and XSS filters.
  • Rate-limiter-flexible - API rate limiting middleware for controlling traffic.

Passport.js

Passport makes handling authentication in Node.js a breeze:
