Installation

npm i cjr

How to use

const cjr = require('cjr');

cjr.fetch('http://echo.jsontest.com/user/JappaBR')
    .then(res => console.log(res))
    .catch(console.error);

    // { user: 'JappaBR' }

In the next requests, the server will not be requested, it will return the value stored in json.

// Request response time comparison
const cjr = require('./main.js');
const options = { isCached: true };

async function run(counter) {
    console.time(counter);
    const res = await cjr.fetch('http://echo.jsontest.com/user/JappaBR', options);
    console.timeEnd(counter);
    console.log(res);
};

(async() => {
    for(let i=0; i<3; i++) await run(i)
})();

// 0: 424ms
// { cached: false, data: { user: 'JappaBR' } }
// 1: 0.82ms
// { cached: true, data: { user: 'JappaBR' } }
// 2: 0.79ms
// { cached: true, data: { user: 'JappaBR' } }

Options

isCached(boolean) [false] - If true, will return along with the response whether the value from cache or not.
timeout(number) [30] - The timeout (in seconds) to ignore cache and fetch again.
dir`` - The channel id where you write messages to.
