⚡ Write a generateInvoice() Function using Kotlin

[PineappleIOnic]

💭 Introduction

Appwrite Functions allow you to extend and customize your Appwrite server functionality by executing your custom code 🤩 You can learn more in our official Appwrite Functions docs.

The backbone of Appwrite Functions is Open Runtimes, an environment for serverless cloud computing. Since all Open Runtime functions are valid Appwrite functions, we are looking for contributors to extend the Open Runtimes Examples repository.

Your task is to implement generateInvoice() function using Kotlin. Please make sure to look at existing function examples and use them as a template for your function. This will help you keep the proper structure as well as provide information on how to test the function.

⚡ Function Details

Generate a PDF invoice. Please avoid using 3rd party services, but feel free to use a library. The payload must provide all invoice details, and a PDF in base64 format should be returned. Regarding customer and issuer, please support \n as a symbol for breaking lines. Invoices usually have 4-5 lines of information for both which include for instance name, address, and phone number.

Example function payload:

{"currency":"EUR","items":[{"name":"Web development","price":15}],"issuer":"Some\nIssuer","customer":"Some\nCustomer","vat":21}

Successful function response:

{"success":true,"invoice":"iVBORw0KGgoAAAANSUhEUgAAAaQAAALiCAY...QoH9hbkTPQAAAABJRU5ErkJggg=="}

Error function response:

{"success":false,"message":"Please provide a currency."}

🎯 Requirements

• Experience with Appwrite.
• Experience with Kotlin.
• Knowledge to implement generateInvoice function.
• Experience with Docker.

✅ Task Summary

• Ask to be assigned to the issue.
• Implement function generateInvoice() in Kotlin/ folder.
• Manually execute the newly implemented function to ensure it works.
• Submit a pull request in open-runtimes/examples and include screenshots of successful execution.
