Organizing Code with Import/Export Lab

Learning Goals

  • Use the default and named import/export syntax to access variables across multiple files

Instructions

In this lab, we'll work on organizing our code into separate files with the import/export syntax. We'll continue working on the portfolio example from the previous lab, this time working on separating out our code into different modules using the import/export syntax.

Begin with npm install. Then, run npm start to run your code in the browser. Follow the error messages to fix the broken imports!

Your goal is to fix the errors, and get our app to match this example:

demo

When you're done, run npm test to check if all tests pass.

Deliverables

Components

There are four components in this application, all located in the components folder. Use the default export syntax to export the <About>, <Home>, and <NavBar> components, and import them all in the <App> component.

Data

In the src/data/user.js file, there are three variables that have information about the owner of the portfolio site. Export all three variables using the named export syntax.

After you've exported them, import them in the following files:

  • Import the username and city variables in the src/components/Home.js file
  • Import the image variable in the src/components/About.js file

When importing, make sure to use the relative path from the file you're currently in, to the file you're trying to import from. For example, if you are in the src/components/About.js file and want to import from the src/data/user.js file, the relative path is ../data/user (go up one directory, into the data folder, and into the user file).
