Description

You can respond to requests with a file using the res.sendFile(path) method. You can put it inside the app.get('/', ...) route handler. Behind the scenes, this method will set the appropriate headers to instruct your browser on how to handle the file you want to send, according to its type. Then it will read and send the file. This method needs an absolute file path. We recommend you to use the Node global variable __dirname to calculate the path like this:

absolutePath = __dirname + relativePath/file.ext

Instructions

Send the /views/index.html file as a response to GET requests to the / path. If you view your live app, you should see a big HTML heading (and a form that we will use later…), with no style applied.

Note: You can edit the solution of the previous challenge or create a new one. If you create a new solution, keep in mind that Express evaluates routes from top to bottom, and executes the handler for the first match. You have to comment out the preceding solution, or the server will keep responding with a string.

Tests

tests:
  - text: Your app should serve the file views/index.html
    testString: 'getUserInput => $.get(getUserInput(''url'')).then(data => { assert.match(data, /<h1>.*<\/h1>/, ''Your app does not serve the expected HTML''); }, xhr => { throw new Error(xhr.responseText); })'
