Note: If you are working locally, make sure that you have node.js installed in your computer by typing in your terminal:

$ node -v

This project comes with the necessary files to start working immediately.

We recommend opening this very same repository using a provisioning tool like Codespaces (recommended) or Gitpod. Alternatively, you can clone it on your local computer using the git clone command.

This is the repository you need to open:

https://github.com/breatheco-de/exercise-conditional-profile-card.git

👉 Please follow these steps on how to start a coding project.

To see the result in the browser, you will need to start the project by running the following command in your terminal:

$ npm run start

💡 Important: Remember to save and upload your code to GitHub by creating a new repository, updating the remote (git remote set-url origin <your new url>), and uploading the code to your new repository using the add, commit and push commands from the git terminal.

As a web developer, you will be creating lots and lots of dynamic HTML using JavaScript based algorithms.

In this exercise, you have to create the HTML code needed to render a profile card based on a series of variables that could change in value during runtime. Here is an example of the profile card:

Inside the src/app.js file there is a render function that receives variables and contains the logic to create most of the website HTML code.

function render(variables = {}) {
  document.querySelector("#widget_content").innerHTML = `<div>Website code</div>`;
}

You can see the variables that are being generated by typing on the developer console:

console.log(window.variables);
/*
{
    includeCover: true, // if includeCover is true the algorithm should show the cover image
    background: "https://images.unsplash.com/photo-1511974035430-5de47d3b95da", // this is the image's url that will be used as a background for the profile cover
    avatarURL: "https://randomuser.me/api/portraits/women/42.jpg", // this is the url for the profile avatar
    socialMediaPosition: "left", // social media bar position (left or right)
    
    twitter: null, // social media usernames
    github: "alesanchezr",
    linkedin: null,
    instagram: null,

    name: null,
    lastName: null,
    role: null,
    country: null,
    city: null
}
*/

These instructions come with a video for better understanding: https://youtu.be/gaVm8eyCqlM

1. Read and understand the render function and the value of the variables variable that it receives.

2. Change the content of the render function to make it render the variables on the card.

You do not need to add any event listeners to the elements that are already built in the project. This is already being done by this part of the code:

document.querySelectorAll(".picker").forEach(function(elm) {
    elm.addEventListener("change", function(e) {
      // <- add a listener to every input
      const attribute = e.target.getAttribute("for"); // when any input changes, collect the value
      let values = {};
      values[attribute] =
        this.value == "" || this.value == "null"
          ? null
          : this.value == "true"
          ? true
          : this.value == "false"
          ? false
          : this.value;
      render(Object.assign(window.variables, values)); // render again the card with new values
    });
  });

So when the elements contents "change" they will already update the variable values for each element. All you need to do is to update the HTML content inside render function, as mentioned on instruction 1.

This is an example of a possible HTML output, you will have to replace the name, last name, etc. With the values that these variables may have.

<div class="widget">
  <div class="cover"><img src="https://the_url.com/for_the_background.png" /></div>
  <img src="https://the_url.com/for_the_image.png" class="photo" />
