Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@futurert/rescript-koa) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

NPM npm

You should add "@futurert/rescript-koa" in bs-dependencies, just like this:

{
  "name": "rescript-project-template",
  "version": "0.0.1",
  "sources": {
    "dir" : "src",
    "subdirs" : true
  },
  "package-specs": {
    "module": "commonjs",
    "in-source": true
  },
  "bs-dependencies": [
    "@futurert/rescript-koa",
  ],
  "warnings": {
    "error" : "+101"
  }
}

Get First Koa App

Koa is great for its middleware design, we just can use sync function as app->use() function params, just like here:

open KoaJs.Koa
// init koa app
let app = koa(koaOptions())

// Just for instance.
// app.env = "development"

// you can use middleware like this
app->App.use(async (context, next) => {
  Js.log("1")
  context.body = "hello"
  await next();
  Js.log("2")
})

app->App.use(async (_, next) => {
  Js.log("3")
  await next()
  Js.log("4")
})

app->App.env("哈哈哈")

app->App.listen(~port = 3000, ~host= "127.0.0.1", ~callback= _ => Js.log("哈哈哈"))
// Js.log(app->App.env) 

// app.listen()
app->App.on("error", (err, ctx) => Js.log(err))
