    例: Bolt + jsx-slack const { App } = require('@slack/bolt')

    const { jsxslack } = require('@speee-js/jsx-slack') const app = new App({ /* ...set tokens... */ }) app.message('hi', ({ message, say }) => { say({ blocks: jsxslack` <Blocks> <Section> Hello, <a href=${'@' + message.user} />! </Section> </Blocks> ` }) }) 17 17

    JSX transpiler 使⽤時 (Babel, TypeScript など) /** @jsx JSXSlack.h */

    import { App } from '@slack/bolt' import JSXSlack, { Blocks, Section } from '@speee-js/jsx-slack' app.message('hi', ({ message, say }) => { say({ blocks: JSXSlack( <Blocks> <Section> Hello, <a href={'@' + message.user} />! </Section> </Blocks> ) }) }) 18 18
