Server engineering documentation

This page documents the structure and the internal architecture of the GraphQL Engine Server. To get started, you can read the overview. We also maintain a glossary of all the terms we use throughout the code and the documentation.

You can also get started with a list of tips and tricks.

Haddock documentation

You can browse the engine's haddock documentation for the stable branch, main branch, and every previous version release since v2.2.0.

Notes

In our Haskell codebase, we use GHC-style notes for long-form comments detailing a specific aspect of the codebase. We gather all of them, as of the main branch, in the notes subfolder.

Updating this documentation

All markdown files in this folder are either copied verbatim from server/documentation or generated as part of our CI; do not open a PR to modify files in the gh-pages branch, and instead modify their source directly. Notes are extracted using the scripts/extract-nodes bash script. The haddock documentation is generated by running cabal haddock --haddock-internal --haddock-options="--ignore-all-exports".
