The Scalar Echo Server is an Express server, which replies with the request data. Works well with the Scalar API Client.
npm install @scalar/echo-serverCreate a new Node.js project and run the following code to run your own instance:
import { createEchoServer } from '@scalar/echo-server'
const { listen } = createEchoServer()
listen(5052, () => {
console.log(`🔁 Echo Server listening on http://localhost:5052`)
})No matter which route you hit, the response contains all the request data and looks like that:
{

"host": "localhost:5052",
