The HTML-Template is built with an AsyncAPI React Component. For any changes regarding the styling of the page, rendering of the missing/existing elements, please contribute to the AsyncAPI React Component repository.

If you want make changes in template itself, please follow:

  1. Make sure you have the latest generator installed: npm install -g @asyncapi/generator.

  2. Modify the template or its helper functions.

    NOTE: If you have to modify the dummy.yml file to develop your features, open a PR with the changes in the asyncapi/generator repository.

  3. Generate output with watcher enabled: npm run develop.

    NOTE: If your changes are not visible, this is maybe because the ag use the already installed html-template so you should use the --install option

    • run npm run develop:install
    • if command failed, delete the cached html-template module in your system and re-rerun the command
  4. Open HTML in your browser: open ./test/output/index.html.
