Note to pg-to-dbml package maintenance developers

If you've cloned the pg-to-dbml repo and are working with the pg-to-dbml source code, be sure to substitute node index for pg-to-dbml when you issue terminal commands.

For example, instead of run pg-to-dbml --help, you would use node index --help.

Linting

We are using ESLint to lint our code as we code and when we push our code. For configuring, see .eslintrc.js and .prettierrc.

Debugging

Running in debug mode in VS Code is easy. Toggle the debugger to auto-attach, and then call from the integrated terminal:

node --inspect-brk --db=DB_NAME --c=postgresql://USER:PASSWORD@HOST:PORT -o='../'

Changelog

All pull requests should include an update to the CHANGELOG that follows the existing pattern there.

Making a Pull Request

When making a pull request, label the PR with the type of semver version bump you wish to make (major, minor, or patch), and Github Actions will take care of the whole release process. It will:

Substitute x.x.x in the changelog with the new version number
Move the changelog to the docs/changelogs directory, and start a new one from a template
Version bump the package.json and package-lock.json
Commit, tag, and push the results to main
Publish the package to Github Packages and NPM
And create a Github Release
