GitHub Release npm version Build Status Coverage Status code style: prettier

Fastify plugin to disable client-side caching

Overview

Inspired by nocache, the fastify-disablecache plugin sets the following response headers and values to disable client-side caching:

Cache-Control: no-store, max-age=0, must-revalidate
Expires: 0
Pragma: no-cache
Surrogate-Control: no-store

This plugin was created out of a need for an easy way to disable client-side caching for data received from backend APIs. This ensures data is always current when called by applications.

Why these headers?

Installation

Install using npm:

npm i fastify-disablecache

For Fastify v3.x support, use fastify-disablecache@2.0.8.

Example usage

const Fastify = require("fastify");
const disableCache = require("fastify-disablecache");

const server = Fastify();
server.register(disableCache);

server.get("/", (req, res) => {
	res.send("ok");
});

await server.listen({ port: 3000 });
