    React for Slack Apps

    Build interactive Slack apps without webhooks or JSON headache. If you know React, you know how to make a Slack app.

    Quick start

    1. Create your message with React:

      import randomImage from "../utils";
      export function RandomImage({ useState }: PheliaMessageProps) {
        const [imageUrl, setImageUrl] = useState("imageUrl", randomImage());
        return (
          <Message text="Choose a dog">
              title="an adorable :dog:"
              alt="a very adorable doggy dog"
            <Divider />
                onClick={() => setImageUrl(randomImage())}
                New doggy
    2. Register your component

      const client = new Phelia(process.env.SLACK_TOKEN);
        client.messageHandler(process.env.SLACK_SIGNING_SECRET, [RandomImage])
      client.postMessage(RandomImage, "@max");
    3. Interact with your message:

    How this works

    Phelia transforms React components into Slack messages by use of a custom React reconciler. Components (with their internal state and props) are serialized into a custom storage. When a user interacts with a posted message Phelia retrieves the component, re-hydrates it's state and props, and performs any actions which may result in a new state.


    Each component is a mapping of a specific object type for a slack block. There are 3 categories of components, each with special rules for how that component can be used with other components.

    1. Surface Components (Message, Home, Modal) - Root components that contains Block Components
    2. Block Components (Actions, Context, Divider, Image, Input, Section) - Direct descendants of a Surface Component. Contains Block Components
    3. Block Element Components (Text, CheckBoxes, TextField, etc) - Direct descendants of a Block Components.
