@gcanossa/gas-http-api

Google Apps Script http api microframework, inspired by expressJs.

Installation

In order to isntall the package in your project just execute the command:

npm i -D @gcanossa/gas-http-api

Usage

The library expose an appBuilder function which allows you to create and configure an http response handler for the special function events doGet and doPost of the Google Apps Script environment.

You can create and configure an app function and use it to handle both special events.

const app = appBuilder(builder => {
  builder
    .use((req, res)=>{
      console.log(req.contextPath)
    })
    .get('/api/:name', (req, res) => {
      respond(res).text(`Hello ${req.pathParams!.name}`);
    })
    .all('/view/:name', (req, res) => {
      respond(res).view('index.e2e', {name: req.pathParams!.name});
    })
});

function doGet(e: GoogleAppsScript.Events.DoGet){
  return app(e);
}

function doPost(e: GoogleAppsScript.Events.DoPost){
  return app(e);
}

It is possible to insert special segments in the mapping url pattern in the form of :name which will be matched against the real request setting the keys of the params member of the request object.

To build the response an helper is available wich allows and simplifies the production of text, downloadable content, json and templated html views.

interface HttpResponseHelper {
  ok():void;
  view(path:string, params:ViewParams):void;
  json(content:any):void;
  text(content:string):void;
  download(content:string, filename: string):void;
  error(error:string):void;
}
