CODE App Assessment

This assessment is designed to assess your skills. For this assessment you do not need to deploy anything. Everything can be developed and tested offline (only for NPM package you need a connection). You should also not need an actual connection with a Shopify store.

Create a shipping label for a return

In most cases we can provide shipping labels from existing carriers. But in some cases you want to create a shipping label which is a simple PDF file that is used as shipping label. The customer then pays for the shipment at the postal office.

Your assignment is to create a PDF label based on a return address that is supplied as argument. In the assets folder there is an sample-label.pdf attached. The endresult should look like that PDF. Furthermore a code-logo.png is attached which can be used in your implementation.

We have setup a simple Express environment that you can use to build your implementation. It can be found in the functions folder. Please implement your solution in the src/shipping-label folder so it will be accessible via the route /get-label.

Your implementation should be testable via this route:

POST https://localhost:3000/get-label

Payload:

{
    "return_address": {
        "company": "CODE Internet Applications",
        "address": "Frederik Matthesstraat 30",
        "zip_code": "2613 ZZ",
        "city": "Delft",
        "country": "The Netherlands"
    },
    "order": "CODE-1339",
    "name": "Test User",
    "language": "en"
}

Requirements

Please do not spend more than 2 hours on this assessment (if it is not finished, please add comments to the code to explain what you would have done if you had more time).

• Build the solution in Typescript
• You may use AI to generate code, but you should understand the code you write
  • Building it without AI has our preference as it better assesses your skills
• Feel free to use any package you want to generate the PDF
• Make an HTTPS endpoint in Express that provides the PDF as output
• Please think about comments in your code (JSDoc)
• Think about a logical way to structurize your code
• Bonus points if you write additional tests for your implementation (please do not use AI to write the tests)
• Bonus points if you make the label multilingual

Please download the code-assessment.zip file and work from there (please do not create a fork of this repository). You may setup a new repository if you want to (it also shows your commits).

Installation and development

• Use npm i or equivalent to install all the package
• Run npm run start to start the server
• You should see Hello world! when you open your browser with the URL https://localhost:3000
