This is the source code for the @goa/koa repository that actually compiles this source code. Please navigate there for the documentation.

Compiled Source Code In 2400 lines.

@goa/goa is the Koa web-sever compiled and optimised with Google Closure Compiler so that it has only 1 dependency (mime-db, for easy access to upgrades). The types are written as JSDoc and don't require installing typings. The aim of this project is to demonstrate how to modernise old-school NPM packages, including starting to use import/export statements without Babel, restoring to pure JSDoc without TypeScript, and compiling the code into a single executable using the compiler, and testing the code with Zoroaster testing framework which is twice as fast and weighs 500KB against 50MB compared with Jest (as used to be used in the original repository).

yarn add @goa/goa

Table Of Contents

Goa

Goa is the same application as Koa. It has the same interface for the app object, as well as context, request and response API.

SourceOutput
import Goa from '@goa/goa'

const app = new Goa()
app.use((ctx) => {
  ctx.body = 'hello world'
})
hello world

Types

The types detailed information can be found 📙 in Wiki. The Koa documentation can be found on its page.

Packages

Koa dependencies as packages had to be rewritten in ES6. Some of them were created as separate packages, and some were included in the source code (repository) in the modules directory.

Show included modules (updated to ES6 and annotated for Node.JS Compiler).
Dependency Type
cache-content-type module
content-disposition module
delegates module
ee-first module
error-inject module
escape-html module
fresh module
http-assert module

parseurl module

The external modules were created with tests also written to ensure their source and compiled versions work as expected.
