1. How to convert Pulumi Output to TypeScript Promise?


    In Pulumi, the Output type represents a value that will only be known at deployment time. You cannot directly convert an Output<T> to a Promise<T> but Pulumi does provide the apply function to interact with the value inside Output.

    However, if you have a scenario where you need to convert the output into a promise, you can use promise() method to achieve this. Here's an example of usage where bucket is a s3.Bucket object:

    import * as aws from "@pulumi/aws"; const bucket = new aws.s3.Bucket("my-bucket"); // Convert pulumi.Output to a Promise const bucketNamePromise = bucket.id.promise(); bucketNamePromise.then(bucketName => { console.log(`Bucket name is: ${bucketName}`); });

    In this code, bucket.id returns a pulumi.Output, which we can convert to a Promise with the .promise() method. The Promise will resolve with the value of the Output at the time the Promise is created.

    Keep in mind though, you should only convert Outputs to Promises if necessary as it defeats the goal of Pulumi's programming model which is designed to not know the values until deployment time. For example, you may tempt to use promise when you need to run a for loop on the Output value, but in Pulumi, you could achieve it by the use of Output.apply function.
