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 🙏

Modules descriptions

Pm2

Production process manager for Node.JS applications with a built-in load balancer for NestJS-mod (Generator ecosystem.config.json for https://www.npmjs.com/package/pm2)

Use in NestJS-mod

An example you can see the full example here https://github.com/nestjs-mod/nestjs-mod-contrib/tree/master/apps/example-terminus.

import { PACKAGE_JSON_FILE, ProjectUtils, bootstrapNestApplication } from '@nestjs-mod/common';
import { ECOSYSTEM_CONFIG_FILE, Pm2 } from '@nestjs-mod/pm2';
import { join } from 'path';

const rootFolder = join(__dirname, '..', '..', '..');
const appFolder = join(rootFolder, 'apps', 'example-terminus');

bootstrapNestApplication({
  globalEnvironmentsOptions: { debug: true },
  globalConfigurationOptions: { debug: true },
  modules: {
    system: [
      ProjectUtils.forRoot({
        staticConfiguration: {
          applicationPackageJsonFile: join(appFolder, PACKAGE_JSON_FILE),
          packageJsonFile: join(rootFolder, PACKAGE_JSON_FILE),
          envFile: join(rootFolder, '.env'),
        },
      }),
    ],
    infrastructure: [
      Pm2.forRoot({
        configuration: {
          ecosystemConfigFile: join(rootFolder, ECOSYSTEM_CONFIG_FILE),
          applicationScriptFile: join('dist/apps/example-terminus/main.js'),
        },
      }),
    ],
  },
});

After connecting the module to the application and npm run build and starting generation of documentation through npm run docs:infrastructure, you will have new files and scripts to run.

New scripts mostly package.json

{
  "scripts": {
    "_____pm2 prod infra_____": "_____pm2 prod infra_____",
    "pm2:start": "./node_modules/.bin/pm2 start ./ecosystem.config.json",
    "pm2:stop": "./node_modules/.bin/pm2 delete all"
  },
  "scriptsComments": {
    "pm2:start": ["Launch all applications in PM2 mode"],
    "pm2:stop": ["Stop all applications in PM2 mode"]
  }
}

Config file for start all built applications ecosystem.config.json

{
  "apps": [
    { "name": "terminus", "script": "node ./dist/apps/example-terminus/main.js", "node_args": "-r dotenv/config" }
  ]
}

Configuration

| Key | Description | Constraints | Default | Value | | ------ | ----------- | ----------- | ------- | ----- | |ecosystemConfigFile|Configuration file for PM2|isNotEmpty (ecosystemConfigFile should not be empty)|-|-| |applicationScriptFile|Application script file name for run|isNotEmpty (applicationScriptFile should not be empty)|-|-| |autorestart|Enable or disable auto restart after process failure.|optional|-|-| |name| An arbitrary name that can be used to interact with (e.g. restart) the process later in other commands. Defaults to the script name without its extension (eg “testScript” for “testScript.js”)|optional|-|-| |script|The path of the script to run|optional|-|-| |args|A string or array of strings composed of arguments to pass to the script.|optional|-|-| |interpreter_args|A string or array of strings composed of arguments to call the interpreter process with. Eg “–harmony” or [”–harmony”,”–debug”]. Only applies if interpreter is something other than “none”.|optional|-|-| |cwd|The working directory to start the process with.|optional|-|-| |output|The path to a file to append stdout output to. Can be the same file as error.|optional|-|-| |error|The path to a file to append stderr output to. Can be the same file as output.|optional|-|-| |log_date_format|The display format for log timestamps (eg “YYYY-MM-DD HH:mm Z”). The format is a moment display format.|optional|-|-| |pid|The path to a file to write the pid of the started process. The file will be overwritten. Note that the file is not used in any way by pm2 and so the user is free to manipulate or remove that file at any time. The file will be deleted when the process is stopped or the daemon killed.|optional|-|-| |min_uptime|The minimum uptime of the script before it’s considered successfully started.|optional|-|-| |max_restarts|The maximum number of times in a row a script will be restarted if it exits in less than min_uptime.|optional|-|-| |max_memory_restart|If sets and script’s memory usage goes about the configured number, pm2 restarts the script. Uses human-friendly suffixes: ‘K’ for kilobytes, ‘M’ for megabytes, ‘G’ for gigabytes’, etc. Eg “150M”.|optional|-|-| |node_args|Arguments to pass to the interpreter|optional|-r dotenv/config|-| |time|Prefix logs with time|optional|-|-| |wait_ready|This will make PM2 listen for that event. In your application you will need to add process.send('ready'); when you want your application to be considered as ready.|optional|-|-| |kill_timeout|The number of milliseconds to wait after a stop or restart command issues a SIGINT signal to kill the script forceably with a SIGKILL signal.|optional|-|-| |restart_delay|Number of millseconds to wait before restarting a script that has exited.|optional|-|-| |interpreter|The interpreter for your script (eg “python”, “ruby”, “bash”, etc). The value “none” will execute the ‘script’ as a binary executable.|optional|-|-| |exec_mode|If sets to ‘cluster’, will enable clustering (running multiple instances of the script).|optional|-|-| |instances|How many instances of script to create. Only relevant in exec_mode ‘cluster’.|optional|-|-| |merge_logs|If true, merges the log files for all instances of script into one stderr log and one stdout log. Only applies in ‘cluster’ mode. For example, if you have 4 instances of ‘test.js’ started via pm2, normally you would have 4 stdout log files and 4 stderr log files, but with this option set to true you would only have one stdout file and one stderr file.|optional|-|-| |watch| If set to true, the application will be restarted on change of the script file.|optional|-|-| |force|By default, pm2 will only start a script if that script isn’t already running (a script is a path to an application, not the name of an application already running). If force is set to true, pm2 will start a new instance of that script.|optional|-|-| |ignore_watch|-|optional|-|-| |cron|-|optional|-|-| |execute_command|-|optional|-|-| |write|-|optional|-|-| |source_map_support|-|optional|-|-| |disable_source_map_support|-|optional|-|-| |env|The environment variables to pass on to the process.|optional|-|-|
