How to interact with REST APIs from JavaScript

How to run the Flask app

We've provided you with a sample REST API in the form of a Flask app.

To run it, you'll need Python 3 and Pipenv installed. Then, do:

cd backend
pipenv install
pipenv run flask run

What does the app do?

The app stores movies. It has two endpoints, POST / and GET /movies.

Adding movies

To add a new movie, send either form or JSON data containing title and year to the POST / endpoint.

See the examples vanilla-post-form.html, vanilla-post-json.html, and fetch-post.html.

Retrieving movies

To get the movies currently stored, send a request to GET /movies.

See the examples vanilla-get.html and fetch-get.html.

How to run the examples

Once the Flask app is running, just open the appropriate example file in your browser.

For example, on Windows, navigate to file:///C:/Users/bob/vanilla-get.html (or whatever path your file is in).
