QUESTION Using module.exports.dependencies in a flow

[tws101]

QUESTION What is the command to install a dependency when processing it from a flow plugin?

I am new to writing flows and I have noticed that the command

module.exports.dependencies = ['@cospired/i18n-iso-languages'];

does not install @cospired/i18n-iso-languages which I get an error when initializing with var languages = require("@cospired/i18n-iso-languages");

A classic plugin will install this with this command module.exports.dependencies = ['@cospired/i18n-iso-languages'];

but a flow is not doing so

This was hard to detect as on tdarr reboots a flow using this would fail BUT once a classic plugin that called this it installs and the flow starts working....

can the above bolded question be answered so I can fix the code in my flow

Below are two use case examples that will fail after a reboot with only flows running

Example code block

const languages = require('@cospired/i18n-iso-languages');
const result2 = (languages.getAlpha2Code(nativeLang, 'en'));
const result3 = (languages.alpha2ToAlpha3B(result2));

Second example code block

const languages = require('/app/Tdarr_Node/assets/app/plugins/node_modules/@cospired/i18n-iso-languages');
const result2 = (languages.getAlpha2Code(nativeLang, 'en'));
const result3 = (languages.alpha2ToAlpha3B(result2));

I have managed this work around

If anyone knows the proper method to do this please let me know

Yes that's one way to do it although you shouldn't need to specify the full path when requiring the dependency. This should work const languages = require('@cospired/i18n-iso-languages'); as NodeJS automatically traverses up the directory tree until it finds a node_modules folder with @cospired/i18n-iso-languages in.

In terms of installing dependencies in flow plugins, I didn't implement the previous way as from what I can remember the npm module (https://www.npmjs.com/package/npm) dropped support for installing other dependencies from within js files so args.installClassicPluginDeps uses an older version which should be fine for now.
