Build a high-performance easily-extensible GraphQL schema by combining plugins.
NOTE: you might actually be looking for PostGraphile (previously 'PostGraphQL') which can be found here; the schema building tools in this repository are used to power PostGraphile among other things.
This repository is a monorepo (managed by lerna) which comprises the following packages:
graphile-build: The core package: a simple plugin system that enables you to build a GraphQL schema out of plugins
graphile-build-pg: A selection of plugins related to PostgreSQL: schema introspection, generation of fields and types for all tables, computed columns, query procedures, etc - if there's certain features you don't want, simply don't use that plugin! (Surfacing plugin dependencies has not been built yet, so be careful when you disable a plugin.)
postgraphile-core: Intended to be used by [PostGraphile][] in order to provide its schema functionality (excluding HTTP handling, etc)
graphql-parse-resolve-info: Parses a GraphQLResolveInfo object into a tree of the fields that are being requested to enable optimisations to your GraphQL schema (e.g. we use it to determine which fields are required from the SQL database)
graphile-build - working (but needs tests, more documentation, refactoring, and probably needs to support more hooks)
graphile-build-pg / postgraphile-core - working - passes the PostGraphQL v3 integration tests for queries and mutations
graphql-parse-resolve-info - complete (but needs dedicated tests because it's currently only tested by virtue of the postgraphile-core tests depending on it)
This system grew out of a need for more efficient SQL queries, easier extensibility and customisation in PostGraphQL. I'm extremely grateful to Caleb Meredith for the stellar work he put into PostGraphQL, and to the community who helped me come up with this idea.
install -g lerna yarn
a bootstrap
run watch
Watch will keep monitoring and compiling the babel files. Then to run the tests in another terminal:
a run test
If the above succeeds, you're good to go! If not, please reach out on twitter: @benjie.
If you want to work in a docker environment you can follow the instructions on the wiki.
If you get an error like the below:
GraphQL conflict for 'GraphQLObjectType' detected! Multiple versions of graphql exist in your node_modules?
it means the peerDependencies have been installed locally in each package
which is not what we want (we want them installed in the root node_modules.
To solve this, we need to re-bootstrap:
Rf packages/*/node_modules
a bootstrap
