preact-cli-plugin-async

Preact CLI plugin that adds optimized support for async/await via fast-async.

Note: this is now just a copy of preact-cli-plugin-fast-async by @plusCubed.

Why do I want this?

ormally, transpiling async/await produces a large amount of code and depends on a runtime like regenerator-runtime. While that is optimal from a compatibility standpoint, it's not so great for bundle size. Using fast-async, this plugin transforms your async functions into Promises just like you would write by hand!

It transforms this:

async () => await (await fetch('/')).text()

... to something that roughly looks like this:

function () {
    return Promise.resolve().then(function() {
        return fetch("/")
    }).then(function(e) {
        return e.text()
    })
}

Pretty great, right?

Installation

npm i -D preact-cli-plugin-async

... then include it in your project by creating a preact.config.js:

import asyncPlugin from 'preact-cli-plugin-async';
 
export default (config) => {
    asyncPlugin(config);
}
