Description

This PR pulls the Chat JavaScript SDK API reference docs from TypeDoc into MDX.

I have split the content into the following:

  • ChatClient
  • Authentication
  • Connection
  • Rooms
  • Room
  • Room reactions
  • Message
  • Messages
  • Message reactions
  • Presence
  • Occupancy
  • Typing
  • ErrorInfo

I did look at separating out logging into its own section too, but welcome to feedback on that and anything else.

All content has been taken from the existing TypeDocs, plus there are some code examples added in relevant places. I also pulled the relevant authentication pieces in from Pub/Sub to save linking out to that.

Note: I've not added meta_description or meta_keywords yet until the general format is approved.

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Explain this complex logic.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai explain this code block.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and explain its main purpose.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Support

Need help? Create a ticket on our support page for assistance with any issues or questions.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

  • @coderabbitai summary to regenerate the summary of the PR.
  • @coderabbitai generate docstrings to generate docstrings for this PR.

Like this - keeps error types separate from everything else as its a generic concept.

I would call out explicitly that the type comes from the ably package and not @ably/chat - as that's an often missed thing.

Definitely worth a try/catch example here to show import + usage

Perhaps worth mentioning in "subscribe / unsubscribe - style interfaces"?


## StatusSubscription

An interface that represents a subscription to status change events. It also provides a method of cleaning up subscriptions that are no longer needed.

"change events, that follow the on/off pattern"? Or something to give context?

I think this sort of snippet is an opportunity to show more detail, e.g. - go and call historyBeforeSubscribe again, etc.

Do we want the API refs to have more contextual bits like this? Looking at examples like React, it feels like a good shout for more complicated cases

Should we call out the JWT format here?
