This plugin lists // TODO comments in source code. It currently exports a single component extension for use on entity pages.

For this plugin to work, you must first install and configure the Todo Backend plugin.

From the root of your Backstage project, run the following command:

yarn --cwd packages/app add @backstage-community/plugin-todo

Next, integrate the plugin by adding it as a tab to the catalog entity pages where you want the Todo tab to appear. For example, to enable the tab on service entities, update your EntityPage.tsx file as follows:

// In packages/app/src/components/catalog/EntityPage.tsx
import { EntityTodoContent } from '@backstage-community/plugin-todo';
// Adds the Todo tab to the service entity page
const serviceEntityPage = (
  <EntityLayout>
    {/* other tabs... */}
    <EntityLayout.Route path="/todo" title="Todo">
      <EntityTodoContent />
    </EntityLayout.Route>
  </EntityLayout>
);

Follow this section if you are using Backstage's new frontend system.

Import todoPlugin in your App.tsx and add it to your app's features array:

import todoPlugin from '@backstage-community/plugin-todo/alpha';
// ...
export const app = createApp({
  features: [
    // ...
    todoPlugin,
    // ...
  ],
});

The default parser uses Leasot, which supports a wide range of languages. By default it supports the TODO and FIXME tags, along with @ prefix and author reference through with either a (<name>) suffix or trailing /<name>. For more information on how to configure the parser, see @backstage-community/plugin-todo-backend.

Below are some examples of formats that are supported by default:

// TODO: Ideally this would be working

// TODO(Rugvip): Not sure why this works, investigate

// @todo: This worked last Monday /Rugvip

// FIXME Nobody knows why this is here

Note that trailing comments are not supported, the following TODO would not be listed:

function reverse(str: string) {
  return str.reverse(); // TODO: optimize
}

The scanner also ignores all dot-files and directories, meaning TODOs inside of those will not be listed.
