Tips

Set custom value via package.json

If you want to fill columns (ex: applications) automatically, you should write webextension column on project's package.json.

Example

{
  "name": "hoge",
  ...
  "webextension": {
    "name": 'extension-name',
    "applications": {
      "gecko": {
        "id": "sample-extension@example.org",
        "strict_min_version": "47.0a1"
      }
    }
  }
}

inherit value from package.json

When name, version, author, description or homepage_url is filled inherit, manifest.json's field will be filled by same key name value from package.json (homepage_url will be filled by homepage in package.json)
