Ballerina First Connector

Welcome to the Ballerina First Connector project! This README will guide you through the basics of Ballerina and how to create a connector to interact with external services.

Learning Outcomes

1. Understanding Ballerina Basics:

   • Imports: I learned how to import necessary modules in Ballerina, such as ballerina/http for HTTP client functionality and ballerina/io for input/output operations.
   • Main Function: I understood the structure of a Ballerina program, including the main function which serves as the entry point.

2. HTTP Client Usage:

   • Creating an HTTP Client: learned how to create an HTTP client using http:Client to interact with external services.
   • Making HTTP Requests: understood how to make HTTP GET requests using the get method of the http:Client object.
   • Handling Responses: learned how to handle HTTP responses, including checking for errors and extracting the payload.

3. Error Handling:

   • Using check: learned how to use the check keyword to handle errors in Ballerina. This ensures that any errors encountered during the execution of a statement are propagated up the call stack.

4. Working with JSON:

   • Extracting JSON Payloads: understood how to extract JSON payloads from HTTP responses using the getJsonPayload method.
   • Printing JSON Data: learned how to print JSON data to the console using the io:println function.

5. Project Structure and Configuration:

   • Ballerina Project Structure: gained knowledge about the typical structure of a Ballerina project, including the use of configuration files like Ballerina.toml.
   • Gradle Integration: learned how to integrate Gradle with a Ballerina project for building and managing dependencies.

6. Sanitization Practices:

   • Input and Output Sanitization: understood the importance of sanitizing inputs and outputs to ensure data integrity and security.

7. Running Ballerina Programs:

   • Using the bal Command: learned how to compile and run Ballerina programs using the bal command.

By working through this project,I have gained a comprehensive understanding of how to create, configure, and run a Ballerina connector to interact with external services.
