Introduction

SQLink is a free and open-source Node.js library designed to simplify database interactions by exposing ready-to-use REST APIs for MySQL.
With SQLink, developers can easily perform essential database operations such as:

  • GET – Read data
  • POST – Create new records
  • PUT – Update existing records
  • DELETE – Remove data

This eliminates the need to manually write boilerplate code for common database tasks.

Architecture​

SQLink Architecture

The diagram illustrates how multiple clients (such as applications or users) interact with a MySQL database through the SQLink REST API:

  1. A client sends an HTTP request to a REST endpoint exposed by SQLink.
  2. The API translates the request into an SQL query and forwards it to the MySQL server.
  3. The MySQL server processes the query and returns the result.
  4. SQLink sends back a structured API response to the client.

Features​

  • Built-in support for executing stored procedures, with argument passing.
  • Streamlined handling of CRUD operations (Create, Read, Update, Delete).
  • Rapid setup with minimal configuration.
  • Fully open-source and extensible for custom requirements.

Use Cases​

SQLink is particularly useful for:

  • Front-end developers who want to quickly connect their apps to a database without writing backend code.
  • Prototyping applications, where speed of development is critical.
  • Learning environments, helping beginners understand database interactions through simple APIs.
  • Personal projects, enabling faster iteration and experimentation.

By handling backend boilerplate, SQLink helps developers stay focused on building features and user experiences.
