feat(build): create transparent builds

[tripodsan]

fixes #1197

• removed parcel dependency
• faster builds
• require source files intuitively

---

a simple html.htl with a html.pre.js is now transformed into:

.hlx/
└── build/
    └── src/
        ├── html.info.json
        ├── html.js
        ├── html.script.js
        └── html.script.js.map

with a generated:

html.js

...
const { pipe } = require('@adobe/helix-pipeline/src/defaults/html.pipe.js');
const { pre, before, after, replace } = require('../../../src/html.pre.js');
const script = require('./html.script.js');
...

the html.htl was transformed into html.script.js.

---

in case of a pure script, like xml.js with a custom xml.pipe.js:

.hlx/
└── build/
    └── src/
        ├── xml.info.json
        └── xml.js

with a generated:

xml.js

...
const { pipe } = require('../../../src/xml.pipe.js');
const { pre, before, after, replace } = require('@adobe/helix-pipeline/src/defaults/xml.pre.js');
const script = require('./../../../src/xml.js');
...

LGTM. The ../.. is currently a bit tricky for wskdebug because it mounts the .hlx/build folder into the docker container, where ../ doesn’t work, but maybe an option can be added to handle this (base dir vs. entry point file).

yes please, i'd rather not copy the source files to the build folder again....

I assume all the existing tests validate that the build works as before.

yes...some of the tests were modified and the JSX test is skipped. Also, since we don't use parcel anymore, building no longer validates the sources.

What would be needed to keep JSX support?

What would be needed to keep JSX support?

Some sort of JSX processor... but I would (re)add it, once someone asks about it :-)

[trieloff]

The JSX processing is done by babel, which is still in the dependency tree:

helix-cli/package-lock.json

Line 340 in b70d9c7

"@babel/core": {

I cleaned up the dependencies :-) but I'll see what can be done :-)

[tripodsan]

@trieloff I added JSX support again.... no more breaking change :-)
