http-config-cache

Caches JSON configs. Meant for long running processes with configs that update more often than environment variables would.

Installation

npm install http-config-cache

Usage

Really simple. Simply include the module and pass it a URL to some JSON. It will then return a promise that returns the config as an object.

Basic:

const configCache = require('http-config-cache');
const configUrl = 'https://raw.githubusercontent.com/Restocks/http-config-cache/master/static/test.json';
 
configCache(configUrl).then((data) => {
  console.log(data);
}).catch((err) => {
  console.log(err);
});

While specifying a cache expiry:

By default all objects expire every 10 minutes before they're fetched again. You can change that by passing a time variable to the function. time is a number in milliseconds.

// 5 second expiry
configCache(configUrl, 5000).then((data) => {
  console.log(data);
}).catch((err) => {
  console.log(err);
});

While forcing a network request

There's also another option to force a network request and ignore the cache entirely. Here's an example of doing that while respecting the standard cache interval.

configCache(configUrl, null, true).then((data) => {
  console.log(data);
}).catch((err) => {
  console.log(err);
});

Development scripts

We follow the airbnb JS style guide. Tests will fail if you don't. While developing locally, be sure to run npm run lint to lint your code to this standard.

npm run test also runs the tests for the repo.
