    The @pollyjs/node-server package provides a standalone node server as well as an express integration to be able to support the REST Persister so recordings can be saved to and read from disk.


    Note that you must have node (and npm) installed.

    npm install @pollyjs/node-server -D

    If you want to install it with yarn:

    yarn add @pollyjs/node-server -D


    Check out the Node Server documentation for more details.


    This packages includes a fully working standalone node server that is pre-configured with the necessary APIs and middleware to support the REST Persister.

    The Server constructor accepts a configuration object that can be a combination of the below listed Server & API options. Once instantiated, you will have full access to the Express app via the app property.

    const { Server } = require('@pollyjs/node-server');
    const server = new Server({
      quiet: true,
      port: 4000,
      apiNamespace: '/polly'
    // Add custom business logic to the express server'/custom', () => {
      /* Add custom express logic */
    // Start listening and attach extra logic to the http server
    server.listen().on('error', () => {
      /* Add http server error logic */

    Express Integrations

    The @pollyjs/node-server package exports a registerExpressAPI method which takes in an Express app and a config to register the necessary routes to be used with the REST Persister.

    const { registerExpressAPI } = require('@pollyjs/node-server');
    registerExpressAPI(app, config);
