A simple cache system for a single user request, built on the same concepts of data loader.

Install

1npm i @npmteam2024/nesciunt-tempore-occaecati

Usage

1const { Factory } = require('.')
2const factory = new Factory()
3
4factory.add('fetchSomething', {
5  // cache by default, set to false to just do batching
6  cache: true
7}, async (queries, context) => {
8  console.log(queries)
9  // [ 42, 24 ]
10
11  console.log(context)
12  // { some: 'data' }
13
14  return queries.map((k) => {
15    return { k }
16  })
17})
18
19async function run () {
20  const context = {
21    some: 'data'
22  }
23  const cache = factory.create(context)
24
25  const p1 = cache.fetchSomething(42)
26  const p2 = cache.fetchSomething(24)
27
28  const res = await Promise.all([p1, p2])
29
30  console.log(res)
31  // [
32  //   { k: 42 },
33  //   { k: 24 }
34  // ]
35}
36
37run().catch(console.log)

If the query parameter is an object, its cache key will be generated using safe-stable-stringify.
