Vega-lite: Provide non-minified distribution

[al6x]

The current way VegaLite distributed is by including minified version only

<script src="https://cdn.jsdelivr.net/npm/[email protected]"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]"></script>

If error thrown (like example below), it's very hard to figure out what's went wrong

ERROR TypeError: Cannot read property 'length' of undefined

    at Array.reduce (<anonymous>)

Jsdelivr also has unminified bundles at https://www.jsdelivr.com/package/npm/vega-lite?path=build.

@domoritz Can you please formulate your answer in terms of a <script> code line?
In addition, would this be a useful point to add to the vega-lite docs? (e.g in a debugging vega-lite section)

[domoritz]

Sure. I’ll do that when I get back to my computer.

For example, you can load non-minified Vega-Lite with:

<script src="https://cdn.jsdelivr.net/npm/[email protected]/build/vega-lite.js"></script>

I'll add a debugging guide in a follow-up pull request.

Guide is in https://github.com/vega/vega-lite/pull/5725
