Use npm in webpack, not checked in bower packages

[sndrs]

What does this change?

• directs webpack to npm, rather than bower

What is the value of this and can you measure success?

• will mean require/bower can go as one, when the time is right. there's no need to use bower

Does this affect other platforms - Amp, Apps, etc?

no

👍 Amazing

[sndrs]

hit a blocker:

currently we serve videojs@5.4.6 and videojs-ima@0.3.0 (both checked in), but videojs-ima@0.3.0 specifies a dependency of videojs@~5.3. webpack therefore is bundling both, adding 200k to the bundle... trying to work out how to handle it

[sndrs]

raised an issue googleads/videojs-ima#333

[sndrs]

tempted to downgrade our version till ima updates - seems like it might be a while, and we're running (potentially) incompatible versions as it is.

we'll mainly miss out on videojs/video.js#2638.

any feelings either way @SiAdcock @akash1810?

@sndrs 👍 but could we do this in a test to be sure there isn't a detrimental loss of video consumption as a result?

[sndrs]

how long would we have to run it for? according to #11821, it was only to bring it inline with contribs anyway?

[akash1810]

Ah, I wasn't aware of that! In that case, I'm all for downgrading.
