Add PWA

• I followed the contributing guidelines: https://github.com/github/explore/blob/master/CONTRIBUTING.md

I am:

• Suggesting edits to an existing Topic page
• Curating a new Topic page

EDITING AN EXISTING TOPIC PAGE*

I'm suggesting these edits to an existing topic:

• Image (and my file is *.png, square, dimensions 288x288)
• Content (and my changes are in index.md)

Please explain why these changes are necessary:

CURATING A NEW TOPIC PAGE

• I've formatted my changes as a new folder directory, named for the topic as it appears in the URL on GitHub (e.g. https://github.com/topics/[NAME])
• My folder contains a *.png image (if applicable) and index.md
• All required fields in my index.md conform to the Style Guide and API docs: https://github.com/github/explore/tree/master/docs

Please explain why you think this Topic page should be curated:

PWAs are rapidly being added to many SPA frameworks out of the box or with starter kits.

• Angular
• Stencil
• React
• Vue

Thanks so much for your contribution! Without people like you submitting PRs we couldn't run this project. You rock, @abraham!

I'm with @kenchris. Maybe it would be better to remove the created_by field.

[kenchris]

It would be nice to educate people better though

[MikeMcQuaid]

@kenchris Will happily accept PRs to update the created_by field.

[kenchris]

@MikeMcQuaid Is the best way to just remove the created_by or could we refer to a link, like say wikipedia instead?

I think @kenchris raises a very valid point.

I have created a PR for this (#173) and explained my reasoning in (great) detail.

And let me also thank @abraham for taking the time to create this topic. 🎉

Awesome @TalAter!
