This is the reference documentation for the FreeSewing backend REST API.
This documentation is under construction as we are re-working this API for v3.
REST API docs
Also available as OpenAPI specification
The backend hosts its own auto-generated (Swagger) documentation based on the OpenAPI specification (v3): backend3.freesewing.org/docs/
About the FreeSewing backend
The FreeSewing backend handles all user data. Prior to version 3 of FreeSewing, the backend was only used internally as the data store for our frontend, the FreeSewing.org website.
In version 3, we have rewritten the backend with the explicit goal to offer it as a service to users and developers. This allows integration with other tools such as hosted instances of our lab, CLI tools, serverless runners, CI/CD environments and so on.
In other words, we no longer merely provide our own frontend, you can now also use our backend as a service to build your own projects.
Use, don’t abuse
Our backend API runs in a cloud environment and while we do not charge for access to the API, we do need to pay the bills of said cloud provider.
As such, please be mindful of the amount of requests you generate. And if you have big plans, please reach out to us to discuss them first.
We will monitor the use of our backend API and we may at any moment decide to revoke API keys if we feel the use is beyond what we can or want to support.
Database schema
The database schema for the backend is available in the [prisma.schema][prisma] file in our monorepo.
Under the hood
The FreeSewing backend is written in NodeJS on top of Express. It uses Prisma to interface with a SQLite database database, Sanity to store images, AWS SES to send out emails, and pino for logging.
