How do I parse a string array as an object in the stack?

In this guide, we will demonstrate how to parse a string array as an object within a Pulumi stack using TypeScript. This can be useful when you need to convert an array of strings into a more structured object format for further processing or configuration within your Pulumi program.

We will start by defining a string array and then parse it into an object. Finally, we will export the parsed object to verify the transformation.

import * as pulumi from "@pulumi/pulumi";

// Define a string array
const stringArray = ["name:John", "age:30", "city:New York"];

// Function to parse the string array into an object
function parseStringArrayToObject(array: string[]): { [key: string]: string } {
    const result: { [key: string]: string } = {};
    array.forEach(item => {
        const [key, value] = item.split(":");
        result[key] = value;
    });
    return result;
}

// Parse the string array
const parsedObject = parseStringArrayToObject(stringArray);

// Export the parsed object
export const parsedResult = pulumi.output(parsedObject);

Key Points:

• We defined a string array with key-value pairs separated by a colon.
• We created a function parseStringArrayToObject that takes a string array and converts it into an object.
• We used the split method to separate the keys and values and stored them in an object.
• Finally, we exported the parsed object using pulumi.output to make it available in the stack outputs.

Summary:

In this guide, we demonstrated how to parse a string array into an object within a Pulumi stack using TypeScript. This approach helps in transforming simple string arrays into structured objects for better management and utilization in your Pulumi programs.
