Node JS Create a Restful API for beginners JavaScript jQuery

Learn how to build a restful API from scratch using Node and Express, handle get, post, put, and delete requests, and connect a front end with Ajax and jQuery.

Learn to access and use the terminal on Mac or Windows, install node and the package manager, verify the installation with node --version, and prepare a directory for upcoming lessons.

Learn to install and update npm globally, manage permissions with sudo, and initialize a Node.js project by creating directories and running npm init.

Create a node project and set up the main entry point with index.js, run node to see console output, and introduce basic variables, logging, and modules for future lessons.

Explore how to create and import modules in node, export values with module.exports, and require them to build a modular node project.

Set up a localhost http server in Node using the http module, listen on port 3000, respond with hello world, and inspect request and response headers.

Learn to read a JSON file in Node.js using the fs module, parse the data into a JavaScript object, and output the first and last names to the console.

Install a file-watcher tool to auto-restart the server as you save changes, and set up express for cleaner routing and a hello world on port 3000.

Learn to set up and use Postman to test Express routes, sending GET, POST, PUT, and DELETE requests to build and debug a restful API.

Install and configure body-parser middleware for express to parse incoming form data and json, run before routes, and access the parsed content via req.body in route handlers.

Learn how middleware runs before routes, using next to continue processing, access request body, and log messages to validate user credentials in a rest api.

Build a login check simulation with an Express API, using a data object for admin, validating user and password via a post to login, and returning success or fail.

Set up a public folder and static index page using Express static, and define basic user routes (get, post, get by id, put, delete) for a REST API.

Add frontend JavaScript and jQuery to wire up a clickable button, collect username and password, and prepare sending data to the back end for a simulated database.

Send front end user and password data to a Node.js back-end via post to /users, serialize the form, assign an incremental id, and update a simulated database with JSON output.

Set up express routes to output all user information and demonstrate retrieving a single user by id from a simulated data object.

Learn to implement delete and put operations in a Node.js restful API by locating items by id, deleting with splice, and updating via request body in an in-memory data store.

Output all user information from the data object using a jQuery get request and render it on the page as an unordered list.

This lecture demonstrates connecting front-end routes to a Node JS API, enabling delete and update actions via AJAX, using event delegation for dynamic user items and data attributes for IDs.

Learn how to implement a put workflow to edit list items, populate input fields from the selected item, and update data via ajax put with proper form submission.

Generate unique ids by using date and Math.floor in the data object, then update routes to work with your database, build this REST API, and improve the front end.

Refactor a Node.js rest api by creating a helper directory, exporting data from a module, and moving core functions to the helper to clean up index.js.

Enhance the user list interface with styling, inline inputs, and save, view, and delete actions via ajax, while hiding ids and keeping routes intact.

Set up a SQLite database for your node app with npm, create a test database and users table, and perform insert, delete, update, and select.

Bring the database into the front end by wiring routes to perform select, insert, update, and delete operations on the users table, with results rendered in index.js.

Develop a Node.js and Express rest api with get, post, put, and delete routes, sqlite persistence, and a jQuery-based front end tested via Postman.
