2. HTML supported.
3. 4.0 is much faster than 3.0. - benchmark
4. Devtools has been deprecated.

#New loader

The new loader has been introduced in zely. (Read blog)

Enable experimental.useSerpack to use new loader.

import { defineConfig } from 'zely';
 
export default defineConfig({
  experimental: {
    useSerpack: true,
  },
});

#HTML

No more ctx.html like this:

export default [ALL((ctx) => ctx.html('<h1>Hello World!</h1>'))];

Just enable experimental.useHTML,

import { defineConfig } from 'zely';
 
export default defineConfig({
  experimental: {
    useHTML: true,
  },
});

and write .html file.

<h1>Hello World!</h1>
