Build a Stock Market Web App With Node and Javascript

Set up a static public folder, create an index page with a bootstrap template, and configure express to serve static files on port five thousand, including an about page.

Set up nodemon to automatically restart your server on file changes, install with npm install -D, add a dev script in package.json, and run npm run dev for development only.

Learn how to pass variables from the back end to the front end using handlebars to render dynamic stock market data from a third-party API.

Integrate a Bootstrap navbar into the stock market web app and convert static pages to Handlebars templates for a consistent navigation across pages.

Register for the free API, obtain your keys, and learn to access basic stock market data such as price, 52-week high/low, and market cap with a Node and JavaScript setup.

Connect to the API, fetch data, and return the body from an API function to display results on the page, while handling asynchronous timing to prevent undefined outputs.

Define and use a callback function to pause an api call until it finishes, then return the result and display the data on the web page.

Loop through a json object from an api with handlebars to print each key and value on screen, including company name and symbol.
