Installation and Setup
Install React and Relay using
yarn add react react-dom react-relay
Set up babel-plugin-relay
Relay Modern requires a Babel plugin to convert GraphQL to runtime artifacts:
yarn add --dev babel-plugin-relay graphql
"relay" to the list of plugins your
Please note that the
"relay" plugin should run before other plugins or
presets to ensure the
graphql template literals are correctly transformed. See
Babel's documentation on this topic.
See the Migration Setup guide if upgrading an existing Relay app.
Alternatively, instead of using
babel-plugin-relay, you can use Relay with babel-plugin-macros. After installing
babel-plugin-macros and adding it to your Babel config:
const graphql = require('babel-plugin-relay/macro');
Set up relay-compiler
Relay's ahead-of-time compilation requires the Relay Compiler, which you can install via
yarn add --dev relay-compiler
This installs the bin script
relay-compiler in your node_modules folder. It's recommended to run this from a
npm script by adding a script to your
"relay": "relay-compiler --src ./src --schema ./schema.graphql"
or if you are using jsx:
"relay": "relay-compiler --src ./src --schema ./schema.graphql --extensions js jsx"
Then, after making edits to your application files, just run the
relay script to generate new compiled artifacts:
yarn run relay
Alternatively, you can pass the
--watch option to watch for file changes in your source code and automatically re-generate the compiled artifacts (Note: Requires watchman to be installed):
yarn run relay --watch
