ecmcors v0.1.3

ecmcors

Easily configure multiple CORS.

Install

npm install ecmcors
# or
yarn add ecmcors

Usage

Set CORS_ALLOW_LIST environment variable.

# If you have multiple origin, you can specify them by separating them with a comma.
CORS_ALLOW_LIST=http://example.com,http://example.net

# If you want to test on a localhost.
CORS_ALLOW_LIST=http://localhost:3000

If you do not set the environment variables, all origins are not allowed.

Example(express)

const express = require('express');
const ecmcors = require('ecmcors');

const app = express();

// Only authorized origin will be allowed to pass.
app.get('/', ecmcors, (req, res) => {
  res.status(200);
});

const PORT = process.env.PORT || 3000;
app.listen(PORT, () => console.log(`listening on ${PORT}`));
