JavaScript APIs

Getting Started

1. Open your command line and navigate to your repos directory (if you do not have a repos folder, then you can use mkdir repos to create one)
2. Use this template repository to start a new project in your repos folder: git clone <repo_name>
3. cd repo_name to navigate into your new repo directory
4. Start Visual Studio Code and select 'Open Folder'. Then select repo_name to open the folder in the editor (or just type code . in your terminal inside the repo directory)
5. Follow the instructions on the README.md file to complete exercises
6. Open the index.html file to get started

Exercise 1

• Let's play around with API calls to Giphy

1. Open your index.html
2. Beneath the p tag, but before the img tag, add the following:
   • Label, input, and button
3. Feel free to label and style
4. Open your app.js
5. Add an event listener to the button that listens for a click event, and does the following:
   • Selects the img element and assigns it to a variable
   • Selects the input element, grabs the value from the element and assigns it to a variable
   • Then, write a fetch request to "https://api.giphy.com/v1/gifs/translate?api_key=YOURAPIKEY&s="
   • Add the stored input value from above to the end of the api call
   • Make sure that you enable CORS with {mode: "cors"}
   • Chain a .then that takes the response and converts the json to a regular object
   • Chain another .then that takes the result and assigns the image url of the response object to the image tag source
   • Add the .catch method that accepts a callback that console.log's the rejection (if any)
6. If you have added the event listener correctly, and correctly called the Giphy API, then you will be able:
   • Let the user input any keyword to the input box
   • Let the user press the button
   • And display a gif in the image tag depending on the API response for the keyword
