Simple GitHub Action to replace tokens in files.

• files - Glob expression, file name or array of glob/file name
• tokenPrefix - Prefix to use when matching tokens, defaults to #{
• tokenSuffix - Suffix to use when matching tokens, defaults to }#

If you want to replace #{CDN}# and #{CALLBACK}# in all of your JS files, add the action to your workflow like this:

- uses: cschleiden/replace-tokens@v1
  with:
    files: '["**/*.js"]'
  env:
    CDN: https://somecdn.com/...
    CALLBACK: some_value

If you want to use a different token format, you can specify a custom token prefix/suffix. For example, to replace just tokens like {CDN} you could add:

- uses: cschleiden/replace-tokens@v1
  with:
    tokenPrefix: '{'
    tokenSuffix: '}'
    files: '["**/*.js"]'
  env:
    CDN: https://somecdn.com/...
