Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

DEV WEB SERVER

A simple web & API server for your development.

Definition

This project is a NodeJS application that permits to simply and quickly create a WEB local server. It can distribute any static or dynamic data and file. This will be useful to mock an API or serve your web site project.

Features

This application creates, by default, a web server on http://localhost:8080/ that targets the website root from the launching directory.

You can specify :

  • a domain,
  • a port,
  • a target directory for the* web site root*,
  • a response time delay,
  • an set of an API endpoints
  • an root url for routing API endpoints.
  • activate SPA mode.
  • activate CORS.
  • activate cache control.

Default webpage

The default webpage at the website root is index.html.

Favicon

The web server supports using favicon.ico. It has to be located at the site root.

Endpoint verbs

The web server supports all endpoint verbs.

SPA mode

The SPA mode permits to redirect all requests to your base file (default: index.html). This is useful for single page applications with no hashed-base routing system.

Content types

The requested file content types is resolved with mime-types. This tool looks up the content type from the requested file extension. If nothing matches, default content type is used : application/octet-stream.

Required environment

  • A release of NodeJS >= 5.0.0 must be installed on your system.

Installation

Install the package on your system like this:

npm install -g dev-web-server

Un-installation

Uninstall the package by typing the next command:

npm uninstall -g dev-web-server

Uses

Launch server

To launch the web server with default parameters:

dev-web-server

With this command, the application will create a web server :

  • on URL http://localhost:8080/
  • that will target website root to the launching directory
  • without any time delay
  • without API endpoints.

The CLI Parameters

| Parameter | Description | |------------ | ---------------- | | --help or HELP | Display help | | DOMAIN | To choose a domain (default : localhost) | | PORT | To choose a port (default : 8080) | | BASEDIR | relative or absolute path to the website root (default : launching directory) | | DELAY | Time delay in milliseconds before each server response (default : 0 ms) | | ENDPOINTS | relative or absolute path to the file that contains API endpoints (see definition below) | | ENDPONTSROOT | Root URL for routing API endpoints (default : /api) | | SPA | Activate SPA mode (default : false) | | CORS | active CORS headers in responses | | CACHE | active cache control headers in responses |

Examples

dev-web-server DOMAIN 0.0.0.0 PORT 1234 BASEDIR ..\rep\httpdocs DELAY 2000 ENDPOINTS ..\rep\server\my-endpoints.js ENDPONTSROOT /my-api

This command will launch a web server :

  • accessible at url http://mon-domain.fr:1234/
  • that will target website root to the directory ..\rep\httpdocs\
  • with a time delay of 2000ms before each response
  • with API endpoints defined in the file at path ..\rep\server\my-endpoints.js accessible at the root URL /my-api.

The JSON Configuration File

We can use a JSON configuration file at the launching directory : dev-web-server.json. Any argument in the command line will override the corresponding one in this file.

The JSON configuration file has to contain the following properties:

| Property | Type | Description | default value | | --- | --- | --- | --- | | domain | string | Domain name of the server | localhost | | port | numeric | Port number of the server | 8080 | | baseDir | string | relative or absolute path to the website root | launching directory | | delay | numeric | Time delay in milliseconds before each server response | 0 | | endPointsFilePath | string | relative or absolute path to the file that contains API endpoints (see definition below) | null | | endPointsRoot | string | Root URL for routing API endpoints | /api | | isSPA | boolean | Activate SPA mode | false | | withCORS | boolean | Activate CORS headers in responses | false | | withCache | boolean | Activate cache control headers in responses | false |

example :

{
  "domain": "0.0.0.0",
  "port": 13002,
  "baseDir": "./dist/test-pages",
  "delay": 0,
  "endPointsFilePath": "./api-proxy/api.js",
  "withCORS": true
}

Definition of the API endpoints file

The API endpoints can be defined in a NodeJS script file. It has to export a JavaScript hash object. Each one of its properties is endpoint declaration: the key is the URL part string before the endpoints root url (default: /api) and the value is a function to execute.

Endpoint function

The endpoint function permits to define the response. It takes in arguments:

| Argument | Type | Description | | --- | --- | --- | | req | Request | NodeJS request object | | res | Response | NodeJS response object | | params | Object | Hash object parameters of the request (taken from body or the query string) | | sendSuccess | Function | Callback function to call to send a successful response | | sendError | Function | Callback function to call to send a failed response |

Successful callback

The sendSuccess callback allows to send a successful response. It contains the result object of the request. It takes in arguments:

| Argument | Type | Description | | --- | --- | --- | | req | Request | NodeJS request object | | res | Response | NodeJS response object | | result | Object | Result object of the request | | jsonpCallback | 'string' | [optional] JSONP callback function name to activate JSONP response |

Failed callback

The sendError callback allows to send a failed response. It contains the error result object of the request. It takes in arguments:

| Arguments | Types | Description | | --- | --- | --- | | req | Request | NodeJS request object | | res | Response | NodeJS response object | | httpCode | Numeric | HTTP code of the response | | message | string | Error text message | | result | Object | Result object of the request | | jsonpCallback | 'string' | [optional] JSONP callback function name to activate JSONP response |

Example :

var Repository = {
  count:0
};

module.exports = {
  '/example': function (req, res, params, sendSuccess, sendError) {

    // Response result is: '{"test":"coucou","count":1}'.
    // HTTP code is 200
    sendSuccess(req, res, {
      test: 'coucou',
      count: Repository.count++
    });

  },

  '/exampleJSONP': function (req, res, params, sendSuccess, sendError) {

    // Response result is: myCallback({"test":"coucou","count":1}).
    // HTTP code is 200
    sendSuccess(req, res, {
      test: 'coucou',
      count: Repository.count++
    }, params.myCallbackName);

  },

  '/exampleError': function (req, res, params, sendSuccess, sendError) {

    // Response result is: '{"code":401,"message":"An error occurred during doing something"}'.
    // HTTP code is 401
    sendError(req, res, 401, 'An error occurred during doing something');

  }
};
