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 🙏

Greenkeeper badge

www dev server with livereload and file watching for developing Single Page Applications.

Features

  1. Serve static files
  2. File watching of the static files
  3. Livereload when watched files change
    • Starts its own livereload server
    • Automatically inject livereload into your application
  4. Https and Http2 support
  5. Auto generation of self signed certs
  6. Proxy settings with socket support
  7. Built on top of battle tested tools such as Express, chokidar, tiny-lr, and more.

Examples

Hello world

This setup will quickly walk you through starting up a server with ZERO configuration (all default settings). Serve up static assets, monitor them and when they change, livereload will refresh the browser where you are viewing your application.

install 3dub globally

$ npm install 3dub -g

create public folder

By default, 3dub serves up static assets from a directory called public relative where 3dub starts from. So let's go ahead and create one if one does not already exist. All your code goes in there.

$ mkdir public

start 3dub

$ 3dub

view in the browser

$ open http://localhost:3000

Custom port via configuration file

Adding a configuration for 3dub is a way to customize default settings. Generally, you will create configuration files wherever you expect to start 3dub from.

configure 3dub

Create a file called .3dub.js and configure the server port.

module.exports = {
  "port": 4545
};

start 3dub

$ 3dub

CLI examples

All options available for 3dub are for both the CLI and configuration files. Configuration files just makes some situations easier to work with as in the case of defining complex option object when defining middlewares.

start 3dub with custom port

$ 3dub --port 4545

3dub with root directory

$ 3dub --root dest

3dub with http2 and custom port

$ 3dub --mode http2 --port 8443

Configuration

3dub allows you to define a configuration in your project's directory. You can also specify a default configuration file in your HOME directory. If you specify both, the your local project's definition will be mixed in with the settings defined in HOME.

The default name of your configuration is .3dub.json for JSON and .3dub.js for JavaScript. You can alternatively create a .3dub directory with an index.js that contains your settings.

Options (Configuration file and CLI)

CLI only supports subarg notation when working complex object.

  • config (string) Configuration file name to load. By default it will load .3dub.json and .3dub.js files or .3dub directory with an index.js file in it. CLI only

  • log (boolean) flag to disable logging of noisy messages. Defaults to true.

  • port (number) port to for the server to listen on for incoming requests. Defaults to 3000.

  • root (string) path to serve files from. Defaults to public.

  • history (string | object) to configure the history middleware for managing your SPA. For details on the settings, please see here. Defaults to index.html.

  • livereload (number | object | boolean) When false, livereload is disabled. When its a number, then livereload client and server use that as the port number. When it is an object, settings are those used by tiny-lr. If you want to specify different settings for the livereload client and livereload server, then you can define a server and a client object with the corresponding options. Default value is the port number 35729.

  • watch (string[] | object | boolean) When false, file watching is disabled. When string or array of strings, you sepcify the files and directories to be monitored for changes; globs are supported. If options is an object, then they are forwarded to chokidar. watch is only enabled when livereload is enabled. Defaults to the root directory.

  • proxies (array<{source, target}>) Array of objects with a source property for the local url path and a target to the remote url path we are mapping to.

  • middlewares (array<string | object | array> | object) Option to define middlewares to be loaded. You can specify an array of middleware module names, you can also specify an object whose keys are the names of middleware modules and the values are the corresponding options for them. You can also specify middlewares using subarg notation, which is an array where the first item is the middleware module name and the second item are the options for it; e.g. ["middleware-module", options].

  • spdy (object) configure the http2 handler. Please take a look at the spdy module for details on the valid options.

  • mode (string) configure what protocol to run. E.g. http, https, or http2. For https and http2 mode, you must provide the pair cert and key or pfx and passphrase. If you do not provide either, a self signed certificate will be automatically generated for you.

  • cert (string) When using https, the cert option is for specifying the file path to the certificate file to be used by the server.

  • key (string) When using https, the key option is for specifying the file path to the private key file to be used by the server.

  • pfx (string) When using https, the pfx option is for specifying the file path for the pfx file to be used by the server.

  • passphrase (string) When using https, the passphrase option is required for opening the pfx file that will be used by the server.

Self signed certificates

When running 3dub in https or http2 mode, you have the option to specify your own certificate. If one isn't provided, then 3dub will create its own self signed certificate and will log a warning. A self signed certificate is automatically created to make it really easy to get a dev server up and running. And... The self signed cerficate is not written to disk.

Installation

Install via npm as a dev dependency, and configure an npm script to start the server. This is my preferred approach as it allows you to define the version of 3dub on a per project basis and also removes the need to install 3dub globally.

$ npm install 3dub --save-dev

Install globally so that you can start 3dub from anywhere via CLI.

$ npm install 3dub -g

Requirements

For http2 to work as expected, nodejs 4.8.0 and above is required. This is because ALPN was added in that version of node which is required by browsers like Chrome to properly negotiate the protocol.
