* make `jit` mode the default when no mode is specified
* unify JIT and AOT codepaths
* ensure `Object.entries` on undefined doesn't break
It could be that sometimes you don't have values in your config (e.g.: `presets: []`), this in turn will break some plugins where we assume we have a value.
* drop AOT specific tests
These tests are all covered by JIT mode already and were AOT specific.
* simplify tests, and add a few
Some of the tests were written for AOT specifically, some were missing. We also updated the way we write those tests, essentially making Tailwind a blackbox, by testing against the final output.
Now that JIT mode is the default, this is super fast because we only generate what is used, instead of partially testing in a 3MB file or building it all, then purging.
* add some todo's to make sure we warn in a few cases
* make `darkMode: 'media'`, the default
This also includes moving dark mode tests to its own dedicated file.
* remove PostCSS 7 compat mode
* update CLI to be JIT-first
* fix integration tests
This is not a _real_ fix, but it does solve the broken test for now.
* warn when using @responsive or @variants
* remove the JIT preview warning
* remove AOT-only code paths
* remove all `mode: 'jit'` blocks
Also remove `variants: {}` since they are not useful in `JIT` mode
anymore.
* drop unused dependencies
* rename `purge` to `content`
* remove static CDN builds
* mark `--purge` as deprecated in the CLI
This will still work, but a warning will be printed and it won't show up
in the `--help` output.
* cleanup nesting plugin
We don't have to duplicate it anymore since there is no PostCSS 7
version anymore.
* make sure integration tests run in band
* cleanup folder structure
* make sure nesting folder is available
* simplify resolving of purge/content information
