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 Environment Manager

codecov

Command line tools and shortcuts to help make your development life easier.

Dev Environment Manager executes your most utilized commands and takes the guesswork out of remembering long strings of commonly used development commands.



We can define where our commands are executed (locally or inside our Docker containers). For example, if we'd like all of our Composer (PHP) scripts to be executed inside a specific Docker container, we add this configuration inside dev-env-config.yml:

environments:
  docker-compose:
    commands:
      composer:
        container: '<container_name>'
        type: 'exec'

Now, we can simply run:

dev composer install

Behind the scenes, Dev Environment Manager runs:

docker-compose exec <container_name> composer install

🎉

Day-to-day and custom developer commands can be easily defined via the commands directory.

Installation

npm install -g @aftdev/dev-env-manager

This installs dev globally.

dev --help

Note/TODO: dev may already be in use by your system or another npm package. In this case, there would be a naming collision in the case of dev.

Future versions of Dev Environment Manager may change dev to something else and without notice.

Default commands

Run these commands from the root of your project.

init

dev init

Generates the dev-env-config.yml configuration file. Add your configurations and customizations inside this file.

setup

dev setup

Sets up the project environment(s). Useful for getting started quickly inside a freshly cloned project.

By default, this command will execute:

  • docker compose build && docker compose up -d (if a docker-compose.yml exists inside the project)
  • composer install (if a composer.json exists inside the project)
  • npm install (if a package.json exists inside the project)

Note: Your project will most likely require a different setup mechanism, you can easily override this command if needed. See custom commands section.

start and stop

dev [start|stop]
# or
dev [up|down]

Starts or stops all the environments that belong to the "start" group.

On default installations, this is basically a shortcut for docker-compose [up|down]

connect

Uses the "targets" defined by all the environments that belong the "connect" group.
Docker containers are an example of target. Select a target in order to open an SSH connection to it.

$ dev connect
> Select a target to connect to:
- app1
- app2
- app3
- mysql
- redis

# Or, SSH directly to a specific container
$ dev connect app1

# SSH as root
$ dev connect app1 --root

Scripts auto-discovery

Sometimes typing dev composer <script-name> can be repetitive.
Dev Environment Manager will auto-discover scripts from your package managers for you.

For example, using Composer and composer.json:

{
  ...
  "scripts": {
    "test": "phpunit",
    "other-script": "do something else"
  },
  ...
}

Using npm and package.json:

{
  ...
  "scripts": {
    "build": "yarn build",
    "test": "mocha",
  ...
}

Now we can run:

dev other-script # will execute `dev composer other-script`
dev build # will execute `dev yarn build`

Enable auto discovery by adding the following in your dev-env-config.yml file:

# @file ./dev-env-config.yml
package_managers:
  node:
    autodiscover: true
  composer:
    autodiscover: true
    priority: 200

Note: If the same script exists in both files, like test in the example, a prompt will be displayed asking you to pick which manager to use.

❯ dev test
? Select which package manager to use: (Use arrow keys)
  Composer
  Npm

You can change the order of that list by using the priority configuration for each manager.

Important: Commands registered at the application level (such as via Commander) will always take precedence over scripts commands. For example, if you created a custom build command Dev Environment Manager will always run the custom command and not yarn build.

Custom commands

Each project can set its own custom commands:

  1. Set the command folder path(s) in the dev-env-config.yml file
  2. Add command files (js, mjs, cjs) to the commands directory

Project commands will always take precedence over application default commands.

# @file ./dev-env-config.yml
commands_dirs: ./commands
# or array notation
commands_dirs:
  - ./commands
  - ./another_folder
# or object notation (this makes it easier to override)
commands_dirs:
  default: ./commands
  other: ./another_folder
// @file ./commands/my-command.js
export default ({ cli }) => {
  cli
    .command('your-command-name')
    .description('This is my really cool command')
    .action(() => {
      console.log('HELLO')
    })
}
// @file ./commands/my-command.ts
import type { DevCommandInitializer } from '@aftdev/dev-env-manager'

const commandsInitializer: DevCommandInitializer = ({ cli }) => {
  cli
    .command('your-command-name')
    .description('This is my really cool command')
    .action(() => {
      console.log('HELLO from TS')
    })
}

export default commandsInitializer

Note: When using typescript you need to build your command files into a different directory and use that directory in your dev-env-config.yml file.

Services that can be used by your custom commands

  • cli: an instance of commander. The documentation on how to add commands can be found here
  • environmentManager: manager to fetch all your envs from
  • composer: execute composer scripts
  • node: execute npm, yarn or pnpm commands (depending on the configuration)
  • outputFormatter: helpers to style output
  • commandExecuter: execute commands
  • enquirer: create cli prompts with enquirer

The services above are automatically injected into your command initializer functions. Using typescript will help you with type hinting.

Environments

We currently only support docker-compose environments.
You can configure it or create new ones by editing the environments section of the dev-env-config.yml file.

# @file ./dev-env-config.yml
environments:
  local: {}
  docker-compose:
    groups:
      setup: true
      connect: true
      start: true
    options:
      config_files: ['docker-compose.yml']

Groups

Every environments belong to groups, those groups are used when executing the following commands: setup, connect, start, stop

# @file ./dev-env-config.yml
environments:
  docker-compose:
    groups:
      setup: true
      connect: true
      start: true

Commands

You can define where your application commands will be executed by adding them to the commands section of the environment.

# @file ./dev-env-config.yml
environments:
  docker-compose:
    commands:
      composer:
        container: '<php-container>'
        type: 'exec'
      composer-custom:
        command: 'php composer.phar' # allow customization of the command.
        container: '<php-container>'
        type: 'run'
      php:
        container: '<php-container>'
      mysql:
        container: '<mysql-container>'

This will allow you to run those commands:

$ dev composer install # docker-compose exec <php-container> composer install
$ dev composer-custom install # docker-compose run <php-container> php composer.phar install
$ dev php -v # docker-compose exec <php-container> php -v
$ dev mysql -V # docker-compose exec <mysql-container> mysql -V

Environment Manager

All environments should be fetched via the environmentManager service that is automatically injected in your custom command files

// @file ./commands/my-command.ts
import type { DevCommandInitializer } from '@aftdev/dev-env-manager'

const commandsInitializer: DevCommandInitializer = ({
  cli,
  environmentManager,
}) => {
  cli.command('using-env').action(() => {
    // Fetch docker-compose environment and execute status command.
    environmentManager.get('docker-compose').execute(['status'])

    // Start all envs that belong to the start group.
    environmentManager.groupedBy({ start: true }).forEach((env) => env.start())
  })
}

export default commandsInitializer

Supported Environments

Docker-compose

# @file ./dev-env-config.yml
environments:
  env_name:
    type: docker-compose
    # Command options
    commands:
      command_name:
        container: '<container name>'
        type: exec/run
        root: true/false
    # Supported Options
    options:
      # What configuration files to use.
      config_files:
        - docker-compose-customA.yml
        - docker-compose-customB.yml

Vagrant

# @file ./dev-env-config.yml
environments:
  env_name:
    type: vagrant
    # Command options
    commands:
      command_name:
        machine: '<machine name>'

Custom Environments

You can create your own environments by extending the EnvironmentManager.

First step is to add your environment configuration to your dev-env-config.yml file.

# @file ./dev-env-config.yml
environments:
  my-fancy-env:
    type: <customEnvType>
    groups:
      setup: true
      start: true
    options:
      a: option a
      b: option b

The second step is to tell the environmentManager how to build your environment.
To do so, in one of your custom command file, use the extend function.

// @file ./commands/custom-env.ts
import type { DevCommandInitializer } from '@aftdev/dev-env-manager'

const environmentInit: DevCommandInitializer = ({ environmentManager }) => {
  // Define a "factory" for the custom type.
  environmentManager.extend('<customEnvType>', (envOptions, container) => {
    // envOptions = {a: option a, b: option b}
    return {
      isEnabled: () => true,
      setup: () => {},
      connect: () => {},
      start() => {},
      stop() => {},
      execute(command = [], options = {}) {}
    }
  })
}

export default environmentInit

The method accepts a closure, which should return the environment object or class that respond to functions defined in the AbstractEnvironment.js abstract.
The closure receives the environment options and the container instance.

Note: Consider creating a pull request, if you think your custom environment could be used by others.

Configuration

Configuration values are set inside the dev-env-config.yml file.

# Where to find the project's custom commands (.js/.cjs/.mjs)?
# use array notation or object notation for easy overriding data.
commands_dirs: {}
# Environments
environments:
  # Default environment where all "executable bins" are executed by default
  local: {}
  # Docker compose environment (only enabled if config file is found)
  docker-compose:
    # Which groups this environment belongs to
    # This is used by the environment default commands in order to figure out
    # what env to automatically setup, start, connect to.
    groups:
      setup: true
      connect: true
      start: true
    options:
      config_files: 'docker-compose.yml'
# Package manager configuration
package_managers:
  node:
    # Which Node package manager to use (Npm / Yarn / Pnpm)
    manager: 'npm',
    # Auto discover scripts from these package manager files
    auto_discover: true,
    # Priority in case of script name collision with other managers
    priority: 1
  composer:
    auto_discover: true
    priority: 1
