Open Source REST API for Chat with Express, MongoDB, and Heroku

Stream offers a scalable RESTful API for their Chat as a Service product, built using Express, which allows developers to generate JWT tokens, manage users, create channels, and handle messages. The API, designed with scalability in mind, supports user storage via a MongoDB database with Mongoose schema validation, password hashing with bcrypt, and easy deployment options to platforms like Heroku and Kubernetes. The setup involves creating a ".env" file with necessary credentials, and the API structure is organized with directories for routes, controllers, and utilities, supporting versioning for future updates. Developers can clone the open-source repository from GitHub and customize it to their needs, with detailed deployment instructions and support for Docker containerization. The API is fully customizable to support additional functionality, making it a flexible solution for integrating chat capabilities into applications.
