bassics v0.3.0

bassics

bassics is a typesafe reactive frontend microframework for building highly performant client apps with familiar patterns like central, unidirectional state management, actions + reducers, html templates, and routing using esmodules and ready to work directly in the browser without a bundler if desired.

Well, it will be. It's not ready for use yet. Hopefully version 0.1.0 will be published soon.

Example dreamcode

Does not work, this is just my dreamcode for what I want to write.

import { App, html, Send, Update, Template } from 'bassics'

interface State {
  count: number;
}

const initialState: State = { count: 0 }

const app = new App(initialState, { renderOnUpdate: true })

cosnt template: Template = (state: State, send: Send) => html`
  <p>Count is ${state.count}</p>
`

app.mount(document.body, template)

setInterval(() => {
  app.send(increment)
}, 3000)

async function increment (state: State, _send: Send, update: Update): void {
  console.debug('incrementing count soon…')

  // actions can be async, cannot mutate state
  await wait(250)

  // This update call is typesafe and will only compile if the arguments are correct
  state = update(updateCount, state.count + 1)

  console.debug('incremented to ${state.count}')
}

function updateCount (state: State, count: number): State {
  // reducers (or updaters) are always synchronous
  state.count = count
  return state
}

function wait (amount) {
  return new Promise(resolve => {
    setTimeout(() => {
      resolve()
    }, amount)
  })
}

TODO

• Extract from existing project
• Stop passing the store around
• Document example app
• Include render action
• SSR
• Local dev setup?
• Routing?
