apollo-codegen

Apollo client code generator

This is an early prototype of a tool to generate client code based on a GraphQL schema and query documents.

It currently only generates Swift code, and only for a subset of GraphQL queries. Most importantly, fragments are not yet supported. See Apollo iOS client for a more detailed description of the proposed mapping to Swift, as well as runtime support for performing queries.

For example, given the schema and query documents in this directory, apollo-codegen will generate these Swift files.

Usage

If you want to experiment with the tool, you can install the apollo-codegen command globally:

npm install apollo-codegen -g

To download a GraphQL schema by sending an introspection query to a server:

apollo-codegen download-schema http://localhost:3000/graphql --output GitHuntAPI/Definitions/schema.json

To generate Swift code from a set of query definitions in .graphql files:

apollo-codegen generate GitHuntAPI/Definitions/**/*.graphql --schema GitHuntAPI/Definitions/schema.json --output GitHuntAPI/Generated
