HTTP Server

You can create HTTP servers using the cloud.Api standard library.

This example shows an example of using an API with a GET and PUT endpoint that interacts with a bucket.

main.w

bring cloud;
bring http;

let noteBucket = new cloud.Bucket();

let api = new cloud.Api();

api.get("/note", inflight (request) => {
  let noteName = request.query.get("name"); 
  let note = noteBucket.get(noteName);

  return {
    status: 200,
    body: note
  };
});

api.put("/note/:name", inflight (request) => {
  let note = request.body;
  let noteName = request.vars.get("name");

  if (note == "") {
    return {
      status: 400,
      body: "note is required"
    };
  }

  noteBucket.put(noteName, note ?? "");
  // handler implicitly returns `status: 200` by default
});

// Consumer functions (not required for the app to work, but useful for testing)
new cloud.Function(inflight (event: Json?) => {
  if let event = event {
    let parts = event.asStr().split(":");
    let name = parts.at(0);
    let note = parts.at(1);

    let response = http.put("{api.url}/note/{name}", {
      body: "{note}"
    });
    return response.body;
  }

  return "event is required `NAME:NOTE`";
}) as "Consumer-PUT";

new cloud.Function(inflight (event: Json?) => {
  if let event = event {
    return http.get("{api.url}/note?name={event}").body;
  }

  return "event is required `NAME`";
}) as "Consumer-GET";
