The document provides an agenda for building a HTTP web API with Node.js and MongoDB. It introduces Node.js and Express for building network applications, and MongoDB and Mongoose for data persistence. It then demonstrates how to set up an Express project, install dependencies including Express and Mongoose, and connect to a MongoDB database to build and save documents.

- 21. building the web api
- 22. new express project create a folder for the app mkdir workout-tracker create a package.json file { with these contents "name": "workout-tracker", "description": "workout tracker app", "version": "0.0.1", "private": true, "dependencies": { "express": "3.x" } } install dependencies and $ npm install install express
- 23. $ npm ls [email protected] /private/tmp !"# [email protected] $"" [email protected] $"# [email protected] % $"" [email protected] % $"" [email protected] % $"" [email protected] % $"" [email protected] % !""
