Dependencies are wiped on each step of project creation with cordova-lib and NPM 7

Bug Report

Problem

What is expected to happen?

For a cordova project created through cordova-lib node api, with npm@7, we expect the npm packages required by each cordova step/command to be stored and cumulated in /node_modules/ like what's done using npm@6 or with cordova-cli itself with npm@6 and npm@7.

What does actually happen?

Project creation has correct /node_modules/ and runs fine for

• cordova-lib with npm@6 only 😢
• cordova-cli with npm@6 and npm@7 👍

In those 3 cases, the order to add plugins and platform does not matter: plugins first and platform after them, or the opposite, platform first and then plugins.

😢 Using cordova-lib with npm@7 results in incomplete /node_modules/ and so possibly failing project creation (like when a plugin after_prepare hook script called during cordova platform add does not find one of its own dependencies).

Information

Again only since Npm 7, each step is fetching its packages correctly inside /node_modules/ but it is also like wiping its content first. Each call to await cordova.plugin('add', pluginName); or await cordova.platform('add', platformName); will result in its content to have only new deps for current specific plugin or platform.

• add first plugin: its deps are in /node_modules/
• add second plugin: its deps are in /node_modules/ but not those of first plugin (should be, like with cli and npm 6)
• add platform: its deps are in /node_modules/ but not those of the two plugins (should be, like with cli and npm 6)
  • each plugin is now installed for this platform, also calling the after_prepare hook script if present
  • ERROR here if script logically uses one of its own dependencies

Command or Code

(simplified version of my code ; I am working on a basic and easily reusable project to share here soon)

await cordova.plugin('add', 'cordova-plugin-device');
await cordova.plugin('add', 'cordova-plugin-androidx-adapter');
await cordova.platform('add', 'android');

will give such failure

.. // "cordova-plugin-device" added first and ok
.. // "cordova-plugin-androidx-adapter" added second and ok
...
.. // starting _plaftom add_ for "android"
Installing "cordova-plugin-androidx-adapter" for android

Could you please check if passing the option save: true solves your issue?

await cordova.plugin('add', 'cordova-plugin-device', { save: true });
await cordova.plugin('add', 'cordova-plugin-androidx-adapter', { save: true });
await cordova.platform('add', 'android', { save: true });

@raphinesse adding the option save: true solves the issue !! 🎉

When using npm 6 I don't see any difference between with and without this option (mostly for dependencies fetched and stored), while using npm 7 it seems needed to add it 👍

Indeed this option seems to be set to true using cli without options, and mostly none of --nosave or --save : cli.js#L447
