How to Properly Link index.html, client.js, and server.js?

Linking index.html, client.js, and server.js

You've encountered errors while running your application, which stem from a misunderstanding in the file linking. Let's clarify the process:

Request from Browser:

When the user opens the page (index.html), the browser sends a request to the server for client.js.

Server's Response:

The server receives the request and executes the response() function within app.listen(8080):

• It reads index.html and sends its contents back to the browser.

Browser's Interpretation:

However, index.html starts with , indicating it's an HTML document. When the browser receives this response and tries to interpret it as JavaScript (as expected for client.js), it throws an error.

Solution:

The server should handle different requests differently:

• If the requested URL is client.js, the server should send that file back with a content-type of text/javascript.
• If the requested URL is index.html, the server should send it back with a content-type of text/html.

To avoid writing this logic yourself, consider using a framework like Express, which provides easy ways to handle and respond to various request types. The Express getting started guide includes a section on using the static module to serve up static files like client.js and index.html efficiently.
