ng build and serve defaults to AOT

[tmansson]

OS?

Linux (Ubuntu 16.10)

Versions.

ng version
angular-cli: 1.0.0-beta.22
node: 6.9.1
os: linux x64

Repro steps.

Run ng build, ng build --aot and even ng build -aot. They all produce the same files in the dist folder.

Mention any other details that might be useful.

I noticed this because the update to beta.22 broke my absolute paths in ng build and ng serve, this has before been an issue only when running in AOT-mode.

Also, the build times are now 20 to 30 s. From 2 - 3 s before.

And due to #2496 I am unable to run my application as the workaround fails when using AOT.
I'm sure this will be fixed shortly but right now it seems not to be just a default value issue. I tried --aot=false but it made no difference

[rosslavery]

Can confirm. My app is not AoT ready yet, and I can no longer run ng serve.

Running ng serve --aot=false and ng serve --aot false seems to have no effect either.

Edit: Had to downgrade for now. No matter what configs I hacked around with, couldn't get AoT to turn off.

I have also observed that many of our applications don't yet work on AOT, and am surprised to see AOT as the default before is more robust. (Making AOT default eventually is of course a wonderful idea, really looking forward to it.)

[rosslavery]

I get the feeling it wasn't meant to be enabled by default, especially since the flag seems to be having no impact on whether AoT is used or not.

Hoping for a hotfix either way, as I'd like the speed improvements of beta 22 without the brokenness of AoT :D

[clydin]

It should be using the AoT plugin but skipping the code generation step (no ngfactory generation). So any issues with the plugin's typescript compilation are now present in either mode.

Using experimental builds is at your own risks. We're aware of some performance reasons, that's why beta 22 is not released entirely and still tagged experimental.

[tmansson]

The changelog has no indication that this was an experimental release.

The issue here does not regard performance, but rather that it prevents usage unless the application supports AOT.

For myself, I'll continue using this release. But I'd rather this issue not be closed, since it needs to be fixed. If it's been fixed, I'll also like to know about it.

I've deleted comments on this issue that were in violation of Angular's Code of Conduct and banned the user in question.

@bialad we were in the process of releasing the Beta.22 when we discovered an issue that needed investigation, so we kept the Beta.22 in the experimental tag. The official Beta.22-1 has been released.
