webdev's Issues

'webdev serve' on Fedora 28 ProcessException: No such file or directory

Hey. I've been using dart on my Windows 10 machine and had this issue with webdev serve: other person's Stack Overflow Question.
The proposed solution worked for that.

Now I've just built dart on my Fedora 28 machine by somewhat following: this guide

I added this to my path: export PATH="$PATH":"$HOME/.pub-cache/bin" and successfully ran pub global activate webdev

But when I call webdev serve, I get this error message:

$ webdev serve
Unhandled exception:

I think the problem in Command: /home/myUserName/development/dart/dart-sdk/sdk/out/bin/pub deps is that it should say /home/myUserName/development/dart/dart-sdk/sdk/sdk/bin/pub deps.
I do have it this way in my Path for dart as so: export PATH=/home/myUserName/development/dart/dart-sdk/sdk/sdk/bin:$PATH.

I looked through the webdev code to see where I could change this, but couldn't find it.

By the way, the solution in that stack overflow question works for this problem, too.

`build_web_compilers` version – 0.4.0 – is not within the allowed constraint – ^0.3.6

I can't run Angular example apps from within IntelliJ EAP. An attempt results in:

/opt/brew/opt/dart/libexec/bin/pub global run webdev serve web:51764
webdev could not run for this project.
The `build_web_compilers` version – 0.4.0 – is not within the allowed constraint – ^0.3.6.
Dart Dev Server terminated

My app is using 0.4.0. Where is the 0.3.6 constraint coming from, webdev?

Document `entrypointExtensionMarker`

Assuming this is "coordinated" with output from build_web_compilers.

Same with reference to .bootstrap.js in #119

Will make future maintenance easier.

webdev/webdev/lib/src/serve/middlewares/reload_middleware.dart

Line 20 in 2f17ab4

const entrypointExtensionMarker = '/* ENTRYPOINT_EXTENTION_MARKER */';

Support pub global activate webdev

Desired workflow:

1. $ pub global activate webdev
2. Add dev_dependency on webdev
3. In your package directory run $ webdev <command>

Use the same Dart SDK as the one used to invoke the command...

See dart-lang/build#1205 (comment)
https://github.com/dart-lang/pub/blob/master/lib/src/sdk.dart#L13-L26

`build_results_handler_test`s are flaky on Windows

It's likely due to the fact that pumping the event queue isn't enough to ensure that the messages are passed through. Increasing the amount of times we pump could reduce flakiness. Otherwise we can rework the tests entirely.

Add support for `preview-dart-2`

We want to enable preview-dart-2 as soon as we can, even when it is still only a flag for dart2js.

This should both run build_runner on the --preview-dart-2 vm, as well as run DDC and Dart2Js with the --preview-dart-2 flags set.

Open question: do we introduce this as a flag? And when do we make it the default?

Be able to run webdev test on travis

Right now, travis has support for directly running pub run test with extra flags as part of your travis.yml config.
Once we have the ability to run tests directly via webdev, we should add this support to travis.

Just adding the issue here for tracking.

Add analytics

Enable stateless cold reload - reload the entire page on code change

I think this maps to --live-reload in pbr serve – but @jakemac53 would know better

`webdev build` should fail if there are `rest` args

So users aren't confused if they pass in something else crazy...

Latest version of sdk, compilation failed

sdk
dart_2.0.0-dev.64.1-1_amd64.deb
https://github.com/dart-lang/angular/tree/master/examples/hello_world
webdev serve

Enable `serve2` integration tests on Windows

See #101

Please add --delete-conflicting-outputs

It's so annoying that webdev always asks me

Found 1 declared outputs which already exist on disk. This is likely because the`.dart_tool/build` folder was deleted, or you are submitting generated files to your source repository.
Delete these files?
1 - Delete
2 - Cancel build
3 - List conflicts

Ensure up-to-date dependencies

Blocking angulardart/angular#1095.

It's incredibly easy to use an out-of-date set of build_runner, build_web_compilers, and build_test - which, coupled with dart-lang/pub#912, means that users frequently use out of date development dependencies, and when they try and upgrade, hit deadlocks or incomprehensible error messages, i.e (as an example only):

Resolving dependencies...
Package angular_components has no versions that match >=0.9.0-alpha+8 <0.10.0 derived from:
- merck_crm_mashup depends on version ^0.9.0-alpha+8
Process finished with exit code 1

An alternative would be support for peer_dependencies in pub: dart-lang/pub#1837.

Do not live reload if build fails

Live reload works great, but once the build fails it won't work even if you fix the build.

Once solution would be not to reload if the build failed or serve a static page if the build failed that would still keep the connection between the build system and the browser.

webdev crashes on macOS

I tried to use webdev for new dart project but it fails when I run webdev serve or webdev build .
It fails on macOS but it works on my Fedora 28 linux box. I try to run this on this project https://github.com/charafau/json2builtvalue

Dart version:
Dart VM version: 2.0.0-dev.65.0 (Tue Jun 26 14:17:21 2018 +0200) on "macos_x64" (but was the same on 64)

Add support for build_runner's "watch" mode

When working with separate front- and back-end development environments, it would be helpful to support a "watch" feature like build_runner used to that would watch the source for changes and re-compile when a source file is updated, but did not serve the app itself.

For example, I use Go App Engine and thus use their development server for back-end work. build_runner used to let me have the auto-rebuild features with an --output path that would dump the compiled front-end into the appropriate GAE dev_appserver directory. webdev has the watch/rebuild built into the "serve" command but no way to disable actually serving the app.

`serve` command default release mode isn't clear from the help text

> webdev serve --help
Run a local web development server and a file system watcher that re-builds on changes.

Usage: webdev serve [arguments] [<directory>[:<port>]]...
-h, --help                        Print this usage information.
-r, --[no-]release                Build with release mode defaults for builders.
-o, --output                      A directory to write the result of a build to. Or a mapping from a top-level directory in the package to the directory to write a filtered build output to. For example "web:deploy".
...

The -r help text should at least say what the default is (as is done for build).

"webdev build" ate my global CSS files

I have a utility package of Angular components which I use in my apps (think Material components library).
This package comes with global css stylesheet which I used to include in index.html of an app in development like this:

<link rel="stylesheet" href="packages/fnx_ui/css/fnx_ui.css">

It worked with "pub build" but doesn't work with "webdev build". It works with "webdev serve" though.

None of my css files from my package did make it to the final build. Other files from the package (fonts) are there, but not the css files.

Fly as 2.0.0-dev in pubspec and update changelog

webdev/webdev/pubspec.yaml

Lines 1 to 3 in 44d4284

	name: webdev
	version: 1.0.1
	author: Dart Team <[email protected]>

To keep us honest 😄

Meta: AngularDart Conference MVP

In short: pub global activate webdev and then webdev <command>.

• Create a new angular project.
• Serve and debug your project with dartdevc.
• Generate and run test(s).

Nice to have(s):

• Replace the hand-written build.dart's for angular repo (and friends)

Stretch (blocked on build_runner):

• Build your project with Dart2JS.

Enable stateless hot reload - reload changed modules and re-run 'main'

This seems broken w/ latest --hot-reload in build_runner CC @jakemac53 @vsmenon

Fresh out of the box project not serving

So I just discovered this nice package and the possibility to develop angular apps using dart.
I ran the tutorial from https://webdev.dartlang.org/guides/get-started step by step. Funny thing is that it worked one time but most of the time it doesnt finish building when I hit play in phpstorm.
the there is no error message its just repeating this all the time:

Dart VM version: 2.1.0 (Tue Nov 13 18:22:02 2018 +0100) on "windows_x64"
latest phpstorm version: 2018.2.5
and all plugins up to date.

it's really making me sad that I cannot seem to use it.
If you need any further information please let me know.

Hope this helps you to improve or tell me what I'm doing wrong.

After some more digging I found this problem when I run the project:

What can I do to resolve this?

Thanks.

Add support to auto-restart `serve` if the underlying `build_runner serve` stops

Slow loading chrome after refresh

I have issue here, i guess... created starter angular dart, then i compile it. everything is good for now. I go to chrome, to localhost:8080 it take 1second to boot up the starter app. I go to networks and see a lot of files, ddc.js which explain the 1sec time to boot up.
But after refresh page, its still 1 sec. The resources are not cached :( i tried on others browsers like firefox and opera.

With starter angular todo list, the boot up time is about 10seconds!

Using webdev @ 2a7fdca

Bump build_runner to ^0.9.0

build_runner is now at v0.9.0, but webdev checks for ^0.8.2 at:

webdev/webdev/lib/src/pubspec.dart

Line 104 in 0720714

checkPackage('build_runner', new VersionConstraint.parse('^0.8.2'));

I'm not quite sure if any other changes are needed to be honest.

dart source not served when using https

In order to test with https, I use nginx to proxy from https://localhost:3000 -> http://localhost:8080.
If I test using http://localhost:8080, I can see main.dart in chrome's source tab.
If I test using https://localhost:3000, I only see main.dart.js !
The code server is serving up js but not the dart sources ?!

Add a --version flag

build should default to --fail-on-severe

At least for webdev build, we should include the flag --fail-on-severe by default.

Not sure it we want this for serve or not? @jakemac53 ?

If I install protobuf globally with pub global activate protobuf then it stops with this error but goes to the next package it can't find. I've tried to manually install 3 packages but gave up because it could be hundreds of packages.

Sometimes webdev serve auto-rebuild broke the build files

It sometimes happens when I save a file with error and immediately edit to correct it and save it again. And after that it will never rebuild successfully whatever you edit the code unless I remove the .dart_tool and run webdev serve again.

I can reproduce this bug easily.

webdev says the following things.

`webdev build` should output by default

Discussed in an internal thread. For users of builders that are only going to source it isn't always necessary to use --output, but web users generally want to build a deployable directory.

Question is whether we want to wait for the new build_runner and by default add --output web:build

Should also allow --output NONE to get no output and not forward to build_runner.

What is the webdev equivalent of -D option?

I recently upgraded from pub to webdev and noticed that there is no way to set a Dart environment variable (the ones you get using new String.fromEnvironment("x")) when running webdev build or webdev serve. What is the recommended alternative?

webdev build results in "Crash when formatting: [AsciiControlCharacter]"

Environment

Dart VM version: 2.0.0-dev.64.1 (Thu Jun 21 08:47:55 2018 +0200) on "macos_x64"

Steps to reproduce

1. Clone https://github.com/dart-lang/site-webdev
2. cd examples/acx/lottery/1-base
3. pub upgrade
4. pub run build_runner build --delete-conflicting-outputs --output build, and it builds fine
5. webdev build

Expected result

The webdev build should succeed as well. Instead we get:

> webdev build

missing dependency warning gives invalid yaml

Either put the version range in quotes – or use ^ syntax.

webdev could not run for this project.
You must have a dependency on `build_runner` in `pubspec.yaml`.
# pubspec.yaml
dev_dependencies:
  build_runner: >=1.2.2 <2.0.0
You must have a dependency on `build_web_compilers` in `pubspec.yaml`.
# pubspec.yaml
dev_dependencies:
  build_web_compilers: >=1.1.0 <2.0.0

Define option not reachable

On Dart 1.x, when compiling to JS, it was possible to add parameters at compilation time (for instance for version, backend configuration...).

$ pub build --define version=1337

Now, on Dart 2, with webdev build, no option is available to do so.

Add support for --config

For both build and serve

--live-reload doesn't work on macos

It seems that editing the code while

webdev serve --live-reload

is running doesn't refresh anything on macOS.

What I did:

pub global activate stagehand
pub global activate webdev

stagehand web-angular
pub get
webdev serve --live-reload

Then tried to edit both todo_list_component.dart and todo_list_component.html.
A build has been triggered, but nothing happens until I refresh the page.

tried both with dart 2.0.0 and 2.1.0-dev.2.0

---

alternatively, the build step after an editing can take 7+ seconds for a simple label edit.

Merge serve2 -> serve

We only need one command

Any way to configure api proxy?

Created a simple web project with stagehand, how would I configure some of my requests to some other services?

build -r option is a no-op

Apparently the default for build is --release, which makes the shorthand -r a no-op (and actually, made me believe that the default was still debug until @kevmoo corrected me on that). Consider dropping the -r shorthand.

Slow serve and file watching. Memory issues on Safari

The webdev build and webdev serve commands are running slow.

Hello world can take up to 20 seconds on a MacBook. File watch updates can take 5-10 seconds.

Situation with Chrome for updates is better, but Safari is constantly warning This webpage is using significant memory

Log

How can I help debug?

Webdev should check for the latest version and notify before running

Before webdev runs, it should do a request to https://pub.dartlang.org/api/packages/webdev and see if a newer version is available. If there is a newer version it should instruct users to upgrade.

How to use different "build.yaml" files?

Support for --config flag is not planned: see #14

But, from my point of view, it is required : my projects rely on the sass_builder package. This package has an outputStyle option that let you choose between expanded and compressed output.

Using pub run build_runner --config=<debug|release>, I can have expanded output in serve mode, and compressed output in build mode.

How can I reproduce this behavior using the webdev CLI?

Serve on Windows spawns many terminals

Root cause of issue outlined here: #110

I believe one solution is to update the persistent workers in package:build_modules to also start from the snapshot instead of the .bat files.

Create vm service models

It looks like this is going to require a custom builder, probably partying on a yaml file.

Going through the types I am thinking a format like the following:

Config

key	value	default
classes	Map<String, Class>
enums	Map<String, List<String>>

Class

key	value	default
extends	String
fields	Map<String, Field>

Field

key	value	default
type	String
optional	boolean	false
