relay-codemod Build Status

This repository contains a collection of codemod scripts based for use with JSCodeshift that help update Relay APIs.

Setup & run

  • npm install -g jscodeshift
  • git clone https://github.com/relayjs/relay-codemod.git or download a zip file from https://github.com/relayjs/relay-codemod/archive/master.zip
  • jscodeshift -t <codemod-script> <file>
  • Use the -d option for a dry-run and use -p to print the output for comparison

Included scripts

upgrade-store-api-0.8

jscodeshift -t relay-codemod/transforms/upgrade-store-api-0.8.js <file>

Updates method calls on Relay.Store that were removed in Relay 0.8.0:

  • Relay.Store.update => Relay.Store.commitUpdate

upgrade-requires-1.0

jscodeshift -t relay-codemod/transforms/upgrade-requires-1.0.js <file>

Replaces requires to /classic for upgrading to 1.0.0:

  • require('react-relay') => require('react-relay/classic')
  • from 'react-relay' => from 'react-relay/classic'

migrate-to-modern-1.0

jscodeshift -t relay-codemod/transforms/migrate-to-modern-1.0.js <file>

Attempts (in a crude way) to migrate classic APIs to modern ones.

Caveats for initial version:

  • Only translates fragment containers
  • Only works if react-relay is imported/requried as "Relay"
  • Assumes object spread operator is ok to use

Recast options

Options to recast's printer can be provided through the printOptions command line argument

  • jscodeshift -t transform.js <file> --printOptions='{"quote":"double"}'
