Using the current version of angular.dart.tutorial, Using the Chapter_04
With "pub serve", the main.dart.js is a 42337 lines file and the example is working fine.
With "pub build", the main.dart.js is a 22539 lines file and the example is NOT working when I'm serving it through an http web server.
I have the filling that it's something about the transformers.
My concern here is that, I'm working on a Angular Dart application which is working fine using "pub serve", but when I deploy it through a web application server it's not working.
This web application server will provide services NOT written in Dart on which my client side written in Dart with Angular.dart rely on.
pub serve uses --mode=debug by default, pub build (from console) uses --mode=release as default.
I haven't tried pub serve --mode=release but I assume it results in the same output als pub build.
I tried --mode=release with pub serve but it seems not to have any effect.
Release mode does tree-shaking and minification.

I'm trying to follow other people who had a similar issue like this one
Electron-Builder include external folder I wish i could be more specific on what my problem is, the reason is that i dont know whats wrong.
I am making a react app which has a server with an sqlite db and im trying to use electron.js to make it into an installable/executable
here is my dummy repo https://github.com/Juan321654/electron_react_with_build_installer_sqlite_db the master branch was just how to make electron work with react, the server branch is the one that i need help with
you can clone and just do npm i, npm run start to launch executable. npm run build to build
the code works fine in development mode and even after i make the build project with electron i can launch the executable and it works fine and it reads the data from the database, but as soon as i take the dist folder out of the project to send to someone or install the software, it stops working and it loads the app, but it does not read the data from the server/db, I am not sure if its missing node modules or the server folder, or maybe if im missing some kind of command in my scripts in the package.json?
With the expiration of Dartium that happened just a few days ago, I felt compelled to migrate from dart 1.24.3 to Dart2, even though it is still in dev.
I have although hit a few walls doing so, one of them being related to the architecture of my apps.
I run a nodeJs server, which also acts as a webserver with client side dart.
The problem that I experience with the new dart SDK is that in order for the .dart files to be read in Chrome, they must be served using webdev serve or build_runner serve.
Obviously, these 2 commands act as the file server, which is not what I want since I'm using a nodeJS server.
By using build_runner watch I think I am enabling the build and watch of the .dart files into .dart.js inside of the following directory :
.dart_tool/build/generated//lib
I am also able to serve them from my nodeJS server. What remains is the package directory, I can't seem to find where pub serves gets the following package files:
/packages/$sdk/dev_compiler/amd/require.js
/packages/$sdk/dev_compiler/amd/dart_sdk.js
Does anyone know what build_runner serve does to include them?
Thank you,
There are 2 options for using a different server during development.
Run build_runner serve on a different port and proxy the requests to it from your other server. This has the benefit of delaying requests while a build is ongoing so you don't get an inconsistent set of assets.
Run build_runner watch --output web:build and use the created build/ directory to serve files from. This will include a build/packages directory that has these files in it.
These files are served from the lib directory of the dart sdk itself.
Note that there is another option, which is to use the -o option from build_runner. This will create a merged directory with source and generated files, which you can serve directly without relying on any internal file layout.
I'm using pub serve to run my page. I noticed that there are tools like lite-server for npm, that make sure that after file contents are changed, the web page is automatically refreshed.
Anyone got something like that working for dart using pub serve? I thought maybe some grinder script with the watcher package could make that work?
Pub should handle monitoring and autodeployment of changes itself when run in debug or release mode.
You can verify this works correctly by issuing from your project root
pub serve
then make a change to a html or dart file and verify that the project is automatically rebuilt.
If this is not working, you might try experimenting with the --force-poll option when running pub serve. Per documentation:
--[no-]force-poll Force the use of a polling filesystem watcher.
We are currently working on getting better code coverage for one of our JS libraries. I have the The Intern up and running, and can run tests in the browser. However, our libraries create DOM elements in some of their functions, making it so we can't run JUnit from the terminal because Node.js doesn't allow for DOM construction in tests. Is there a way we can get JUnit code coverage on the html and console output we get when we run The Intern in the browser?
I found the answer. From this link: https://theintern.github.io/intern/#local-selenium
Using ChromeDriver (Chrome-only)
If you’re just looking to have a local environment for developing functional tests, a stand-alone ChromeDriver installation works great.
1. Download the latest version of ChromeDriver
2. Set tunnel to 'NullTunnel'
3. Run chromedriver --port=4444 --url-base=wd/hub
4. Set your environments capabilities to [ { browserName: 'chrome' } ]
5. Run the test runner
Once you have that setup and running, you can run
node_modules/intern/bin/intern-runner.js config=tests/intern reporters=JUnit filename=junit.xml
This will allow the tests to run in a chrome instance, and then output the results to a report that can then be upload somewhere.
I just installed Dart Editor on Ubuntu 14.04, opened the Sunflower demo, right clicked on sunflower.html, chose Run in Dartium, and was faced with "Could not start pub serve or connect to pub." So I went to Google and found the following reasons why this happens:
"Run in Dartium" doesn't invoke "pub serve" correctly for Dart files that aren't in web/ or test/ (But the Sunflower demo files are all in web/)
https://code.google.com/p/dart/issues/detail?id=18990
Project files must be inside "C:\Users[username]\dart" instead of "C:\progs\Dart\projects" (Doesn't help; I'm not on Windows, but would demos that come with Dart Editor be in the wrong place?)
https://code.google.com/p/dart/issues/detail?id=19659
Same problem in recent release shows up on Mac OSX, bug fix promised in that next release (Doesn't help; I'm not on Mac OSX and that next release already came)
https://code.google.com/p/dart/issues/detail?id=19143
Another service is listening on port 8080 (Nope, I checked the ports and also made sure nothing with dart pub serve was already running, plus rebooted a couple of times)
dart error - could not start pub serve or connect to pub
So I found more information that gave me the idea to try pub serve from the command line. So I went to the directory where the sunflower project was placed by the Dart Editor (where the pubspec.yaml is found) and in the command line I typed:
sudo /opt/dart/dart-sdk/bin/pub serve
Which resulted in:
You don't have a lockfile, so we need to generate that:
Resolving dependencies... (1.1s)
Downloading browser 0.9.1...
Got dependencies!
Loading source assets...
Serving sunflower web on http:// localhost:8080
Build completed successfully
Great, I thought, so I opened Chrome and visited http:// localhost:8080 and saw this:
404 Not Found
Could not find asset web in package sunflower.
And in my command line console I saw this:
[web] GET / → Could not find asset sunflower|web.
[web] GET /favicon.ico → Could not find asset sunflower|web/favicon.ico.
I am about to get more aggressive with my Google search and investigation, but I thought I would have this question out here just in case I cannot find the answer. Even though I encounter many obstacles before running my first Dart demo, which makes for a poor introduction (I know, Dart is new), I keep liking what people say about it and I am compelled to get this working. Please help me like Dart. :)
Much appreciated!
I came across similar error and this solved it for me:
1) Move all html/css/dart files to /web directory.
2) Than create a pubspec.yaml with your projects dependences (usually it's "browser" only).
You may try like this, [run]-->[Manage Launches], then unmarked "Use pub serve to serve the application", good luck!
