Summary

This PR adds the logger instance to the app for logging outside of function listeners, as this comment suggests:
slack-samples/bolt-js-starter-template#84 (review) 👾 ✨

Preview

Updated app code can use the app.logger functions once the App is constructed:

const app = new App({
  signingSecret: process.env.SLACK_SIGNING_SECRET,
  token: process.env.SLACK_BOT_TOKEN,
});

(async () => {
  await app.start(process.env.PORT);
  app.logger.info('⚡️ Bolt app started');
})();

Before changes

Using console.log instead of app.logger.info prints the following:

$ node app.js
⚡️ Bolt app started

After changes

$ node app.js
[INFO]  bolt-app ⚡️ Bolt app started

Notes

  • Updates to the example apps are left unchanged in this PR but are planned for a follow up 🙏
  • This is marked as typescript specific since before changes javascript apps could still use app.logger! The change from this PR removes errors if app.logger is used when running tsc 🧱

Thanks for working on this! Looks good to me, but you may want to wait for others' feedback for one or two business days. Also, this PR includes document changes too, so we should release a new version including the change as early as possible once it's merged.

Here's the update for tsc! 🎉

docs/content/reference.md
| `respond` | `action`, `shortcut`, `view`, `command` | Function that responds to an incoming event **if** it contains a `response_url`. `respond` returns a promise that resolves with the results of responding using the `response_url`. For shortcuts, `respond` will **only** work for message shortcuts (not global shortcuts). For views, `respond` will **only** work when using `response_url_enabled: true` for [conversations list](https://api.slack.com/reference/block-kit/block-elements#conversation_select) and [channels list](https://api.slack.com/reference/block-kit/block-elements#channel_select) select menus in input blocks in modals. |
| `context` | All listeners | Event context. This object contains data about the event and the app, such as the `botId`. Middleware can add additional context before the event is passed to listeners. |
| `body` | All listeners | Object that contains the entire body of the request (superset of `payload`). Some accessory data is only available outside of the payload (such as `trigger_id` and `authorizations`). |
| `logger` | All listeners | The application logger with all of [the logging functions](/concepts/logging) for output. |

Looks good to me as well 💯 seem like this was originally set to private and never revisited

This behavior also aligns with the bolt python behavior

@seratch @WilliamBergamin Thank y'all both for reviewing! I'm tagging @lukegalbraithrussell here for awareness on updates to docs, and will plan on merging this right before the next release is tagged - good catch with the docs differences that'd appear with an earlier merge! 📚 ✨

@seratch @WilliamBergamin @lukegalbraithrussell thank y'all all for the reviews! I'm glad that we find another match between js and py with these changes 🐍

We're set to release this in the next version with #2371 and testing continues to pass as expected so I think now's a good time to merge! 🚢 💨 I'll begin the updates to included examples for another PR 🔍
