Twocatz frontend

Week 4 Step 6 ⬤⬤⬤⬤⬤⬤◯ | 🕐 Estimated completion: 5-20 minutes

One Cat isn't enough ~ Meow

Now that we've got a frontend that can only return one picture, let's take it to the next level and return FOUR pictures at the same time. To do this, let's edit our old twoCatz function.

✅ Task:

• [ ] Make sure you're on the twocatz-frontend branch
• [ ] Edit your twoCATZ HTTP Trigger from Week 1 so it takes in 4 parameters (name1, name2, name3, name4) and returns four pictures in base64 with the parameters.
• [ ] Remove the "random name" feature in your Azure Function
• [ ] Commit twocatz/index.js and test your result with Postman

❗Requirements

• Make sure you encode the pictures in base64
• Make sure your parameters are named correctly!
• The Function URL should still be in your TWOCATZ_ENDPOINT secret since you are editing the same function

🚧 Test your Work

Open up Postman again since we are testing an API.

⚠️ Make a GET request with the four name parameters. Do you get a JSON object containing name1, name2, name3, and name4 attributes encoded in base64?

:bulb: Having trouble? Look back to old branches - these skills were all used before!

Ultimate CAT INVASION! ~

Demo: 🐱

It's now time to connect everything together! (catzapp/index.html, catzapp/script.js, and your Azure function)

✅ Task:

• [ ] Make sure you're on the twocatz-frontend branch
• [ ] Create 4 input boxes to accept 4 names, each with an id of name1, name2, name3, and name4 respectively
• [ ] Modify catzapp/script.js so that it calls your Azure Function with the 4 names as parameters
• [ ] Create 4 img tags, each with an id of name1, name2, name3, and name4 respectively
• [ ] Display the outputs of the Azure Function as images in the tags
• [ ] Commit your updated changes to catzapp/index.html and catzapp/script.js

:bulb: If your test doesn't pass the first time, it might be because your Azure Function is slow to respond. Simply re-run the job like this.

🚧 Test your Work

Open up your LiveServer plugin and start your local server. To test your web app:

⚠️ When you enter FOUR NAMES into each of the text boxes, do FOUR CAT PICTURES show up below?

How can Base64 turn into a Cat?

Now that you should've received strings of base64 from your Azure function call, you need some way to display them for the users.

:question: How can I display base64?

:one: Retrieve the base64 values from your API :two: Append `data:image/png;base64,` in front of the base64 data :three: Like you've done previously, modify the `src` attribute of the image tags and set it equal to the string you created in :two: Read more [here](https://www.w3docs.com/snippets/html/how-to-display-base64-images-in-html.html)

• I would add more info about css and maybe not use jquery and just use vanilla js since when you mix jquery's selectors and the vanilla js's document.getElementById, it gets a little confusing
