[WIP] Replace bower dependencies with npm packages

[raphamorim]

Ref: #93

[raphamorim]

Hey @leobalter @gnarf @mgol

I'm having a lot of problems to implement this PR.
One of these is: the lack of support for npm custom packages based on url or git` repos.
So implementations like:

"devDependencies": {
    "jquery-1.5.0": "http://code.jquery.com/jquery-1.5.js",

...doesn't work.

"devDependencies": {
    "jquery-1.5.0": "git+https://github.com/jquery/jquery#1.5.0",

...doesn't work too :/

BTW: I'm using 3.5.3 as npm version.

I think one viable solution is to create a preinstall script to download all jquery-versions and place in node_modules or other place.

What do you think?

[leobalter]

maybe you should copy these files from http://code.jquery.com

[mgol]

Since we keep those files in the repository anyway, I think a good solution would be to create a task that would get a jQuery version (VERSION below) as a parameter and would:

1. Check if https://unpkg.com/jquery@VERSION/dist/jquery.js exists; if not, print an error message & finish. Otherwise, go to the next step.
2. Create an external/jquery-VERSION directory.
3. Download https://unpkg.com/jquery@VERSION/dist/jquery.js & https://unpkg.com/jquery@3.1.1/LICENSE.txt & save both to external/jquery-VERSION/.

Once such a task exist, we could invoke it when we need a new version to be added. If we felt really ambitious we could even check for all versions newer than the newest ones on https://unpkg.com and download all the missing major/minor updates in their latest patch version, removing older patch releases (so e.g. 3.0.0 & 3.1.1 are fine but 3.1.0 should be removed).

We could then remove the whole Bower setup & the bowercopy task.

I'll proceed with @mgol solution (creating a node script to do it) 👍

[raphamorim]

@mgol I've checked and unpkg doesn't have all jQuery versions.

jquery-color use for test the following jquery versions: 1.5.2, 1.6.4, 1.7.2, 1.8.3, 1.9.1, 1.10.2, 1.11.3, 1.12.4, 2.0.3, 2.1.4, 2.2.4, 3.0.0 and 3.1.1.

The Unpkg only have versions above of 1.11.3

[mgol]

unpkg is a CDN sharing npm packages and jQuery has been published to npm only since 1.11/2.1.

The old versions are already there, though, the script will download future versions which will all be on npm so this shouldn't be a problem.

[mgol]

@raphamorim will you have time to finish the PR?

[raphamorim]

Yeah, sorry for delaying it. I'll see it til next friday :)

@leobalter, @mgol.
I was wondering if this PR is worth continuing. It would be valid to continue if we had followed the path using NPM or bower, but they are not yet ripe for it.

But in the end, we'll exchange a download script for another download script.

@raphamorim

It would be valid to continue if we had followed the path using NPM or bower, but they are not yet ripe for it.

I'd remove yet from this statement as npm doesn't plan to add this feature.

I think this PR would be worth to finish to get rid of the deprecated bower, though that's true that we'll have to maintain the download script ourselves then.

What do you think?

[raphamorim]

Yeah, make sense to me.
Also: I'm closing this PR in favor of it.

[mgol]

Also: I'm closing this PR in favor of it.

In favor of what?

[raphamorim]

Sorry, I expressed myself badly haha
In favor of:

though that's true that we'll have to maintain the download script ourselves then.
