Server Data

A feature has been added to execute functions that take a long time to compute or degrade performance only on the first request and then send stored cache data.

import { GET } from '@zely-js/core';
import { setTimeout } from 'timers/promises';
 
async function greeting() {
  await setTimeout(1000);
  return 'Hello, Doe!';
}
 
export default [
  GET(async (ctx) => {
    const { data } = await $store(greeting);
    ctx.send(data);
  }),
];

After the first request, the $greeting function will no longer be executed.

let { data: r } = yield $store(
  $greeting,
  [],
  'pages\\index.ts-586' // unique id
);
e.send(r);

#Dependencies

To handle dynamically changing dependencies, such as parameters (req.params), you can register dependencies with the store.

$store(fn, [someDep]);

Data is separated and stored based on the registered dependency value.

#TTL

The store's default TTL (Time To Live) is 6 minutes. To modify the TTL, enter the following code:

$cache.ttl = 1000 * 60 * 10; // cache ttl: 10m

The $cache instance is declared globally. You don't need to import it.

#Try this feature

This feature works based on serpack.
To use this feature, enable the --serpack flag.
