Async function middleware

The async function middleware provides a custom programming model which allows a webtask to directly return results in an idiomatic way.

Usage

To use the async function middleware, you must create a webtask that exports an async function that returns a result:

module.exports = async function (context) {
  return { hello: context.query.name || 'Anonymous' };
}

1. Set the wt-node-dependencies metadata property to a stringified JSON of an object having @webtask/middleware-compiler and @webtask/async-function-middleware properties whose values are the latest version of the @webtask/middleware-compiler module and this module, respectively. For example:

   {
     "@webtask/middleware-compiler": "1.5.0",
     "@webtask/async-function-middleware": "1.0.0"
   }
   

2. Set the wt-compiler metadata property on your webtask to @webtask/middleware-compiler.

3. Set (or add to) the wt-middleware metadata property of your webtask to contain a comma-separated list containing @webtask/async-function-middleware.

4. Issue requests to your webtask
