Hermit server is a stack that integrates various developer friendly technologies to create the ultimate dev experience.
The schema located at src/hermit/prisma/schema.prisma will auto generate database migrations, a type-safe client, and typescript type definitions for you.
Using apollo-express, Hermit exposes a graph at the path /graphql. Thanks to prisma and graphql-codegen, the resolvers located at src/hermit/services/apollo/resolvers.ts are fully typed.
When you run npm test, hermit uses ts-jest in order to run tests. A new environment is created behind the scenes for every spec file, so that each spec is ran in complete isolation. Jest calculates the code coverage and makes it available under test/coverage.
Using Github Actions and Heroku pipelines, the workflow is the following:
- Commit to your feature branch
- Open a PR from feature branch into main
- Automated tests will run in Github, and coverage 100% is enforced : )
- Once a PR is merged to main, the code will auto deploy to a staging environment
- Using the Heroku pipelines dashboard you can promote to production with a single click
To debug using vscode, simply place a breakpoint and then open package.json. Locate the script you would like to debug, click on Debug, and choose the appropriate script in the dropdown. You can debug both "start" and "test" programs.
