How to use ProcessWire standalone (without DB connection)

[bernhard]

 The PW core comes with many great classes such as WireData, WireArray and so on. Sometimes I'm developing stuff without a running PW instance and I'd love to have the great PW api available there as well. I've mentioned that in the PW Roadmap 2021 thread and Ryan stated: https://processwire.com/talk/topic/24897-weekly-update-– 8-january-2021/?do=findComment&comment=209891

Examples of such classes that might be useful even without a DB connection could be:

With the exception of WireMail, all the classes you mentioned are intended to be available for standalone use. Though it's been a long time since I've used any of PW's classes in that way. This I think is likely an easily attainable thing to support though. Most of the mentioned classes just extend the Wire class, making it the only dependency (and Wire doesn't require a DB connection).

There's no reason why we need a running PW instance with a DB connection for such a code example. Of course I know that it's technically required in many places in the core, but maybe these places could be identified and removed in the future?! 

A DB connection would be needed for WireMail because it is a module type. Installed modules are known from the database modules table. A WireMail module also maintains its settings in the database. Now is is true that the base WireMail class can operate without a database, but WireMail is only useful because it is a module type. Take out the module aspect and WireMail is just an interface to PHP's mail(). 

 

That sounded interesting, so I've tried how that works and created a repo for quick and easy testing so that everybody can try what works and share their findings so that everybody can learn.

The ProcessWire core has many great classes such as WireData, WireArray, WireRandom etc.; Many of them can be used without a running PW installation!

This repo helps testing those features and hopefully will motivate others to share their findings (as PRs). It's as simple as creating a new file in the examples folder!

 

I'd appreciate any help regarding the examples throwing an error! PRs for other examples that you've tried very welcome!

Actually it's a lot easier!

// /path/to/pw/root/standalone.php
<?php namespace ProcessWire;
require "wire/core/ProcessWire.php";
$data = new WireData();
$data->foo = 'foo';
$data->bar = 'bar';
echo print_r($data->getArray());

// execute the script
cd /path/to/pw/root
php standalone.php

How great is that? ?

Would it be possible to use WireHttp as standalone?
