Creating a project

This guide will walk you through the following:

  • Creating your first project
  • Running your project using the Wing Simulator
  • Deploying your project to AWS
Don't have Wing installed?

You can get Wing installed and your IDE setup following our installation instructions.

First let's create an empty directory for your project:

mkdir hello-wing
cd hello-wing

You can use the CLI to bootstrap a new project: Use the new command and then modify main.w to have the following:

wing new empty
bring cloud;

// define a queue, a bucket and a counter
let bucket = new cloud.Bucket();
let counter = new cloud.Counter(initial: 1);
let queue = new cloud.Queue();

// When a message is received in the queue it should be consumed
// by the following closure
queue.setConsumer(inflight (message: str) => {
  // Increment the distributed counter, the index variable will 
  // store the value prior to the increment
  let index = counter.inc();
  // Once two messages are pushed to the queue, e.g. "Wing" and "Queue".
  // Two files will be created:
  // - wing-1.txt with "Hello Wing"
  // - wing-2.txt with "Hello Queue"
  bucket.put("wing-{index}.txt", "Hello, {message}");
  log("file wing-{index}.txt created");
});

Here we defined a queue and a counter. Every time a message is added to the queue, a handler is triggered and creates a file named wing-{counter-index}.txt with the content "Hello, {message}!", and the counter is incremented by 1.

Now that we've written this program, let's run and test it using the Wing Console.
