No source map when deploying a Create React App to Netlify

Deploying to Netlify using create-react-app.

Issue:

  • Not build the source map for production deploy.
  • Have the source map for other builds for debugging.
Solution

  • Solution:

    Add the GENERATE_SOURCEMAP env variable to flag no source map. Edit the netlify.toml to include the variable for use in build contexts.

    netlify.toml

    [build]
  command = "npm run build"
  publish = "build"

[build.environment]
  GENERATE_SOURCEMAP = "true"

[build.production.environment]
  GENERATE_SOURCEMAP = "false"
