QUESTION
I've read similar question ng serve not working in Docker container but I don't understand why do I have to specify a host 0.0.0.0 to run ng serve. For comparison, I ran a simple script with express.js in the same container on the same port and in this case the website was served at localhost:8080 without defining 0.0.0.0 host.
As I understand both servers (ng serve and express.js) are working the same way. Both runs inside container but only express can be accessed in browser and I'm confused why ng serve isn't.
Steps to reproduce:
- Run LTS Node.js container with name
angular-testfrom CLI and publish port 8080:4200
docker container run --name angular-test -it -v ${PWD}:/app/ -p 8080:4200 node:lts /bin/bash - connect to container's terminal
docker container attach angular-test - go to angular project and run
ng serve - go to browser
localhost:8080but returns "The connection was reset The connection to the server was reset while the page was loading. ...` - stop
ng serve - run
node test-expressto start express.js server on the same port4200 - go to browser
localhost:8080and website is loaded without any issue, textExpress.js works!is visible
ANSWER
Answered 2021-Apr-29 at 11:39Express.js utilizes the NodeJs`s method
server.listen([port[, host[, backlog]]][, callback]) see documentation
If host is omitted, the server will accept connections on the unspecified IPv6 address (::) when IPv6 is available, or the unspecified IPv4 address (0.0.0.0) otherwise.
If host isn't specified, Node.js sets unspecified IP address :: or 0.0.0.0 as default. If you want to know what host is being defaulted, call server.address() inside app.listen() where server is an object returned by http.Server which extends net.Server.
QUESTION
I am trying to learn about how to take a Test Driven Development approach when writing Angular apps; I have been following an Introduction to Angular Test Driven Development tutorial.
I am failing at the first hurdle, before I've written any tests.
When I run karma start from the tutorial/ directory I get the error:
Karma v 6.3.2 - connected; test: karma_error An error was thrown in afterAll Uncaught ReferenceError: angular is not defined ReferenceError: angular is not defined at http://localhost:9876/base/app/app.js
How do I get Angular to load?
My current understanding is that angular should load automatically because of the files: [] line in karma.conf.js and app.js should have access to it. At the moment my app.js is creating a basic controller and nothing else and as far I can tell my code matches the code in the tutorial for this stage. The tutorial has a Git Hub repository.
Based on the tutorial, my directory structure is as follows:
...ANSWER
Answered 2021-Apr-12 at 09:07The tutorial suggests you give paths of your application in the wrong order when running karma init.
As app/app.js depends on node_modules/angular/angular.js, the latter should be declared first. To fix the problem, update karma.conf.js to declare:

QUESTION
I am mocking services without TestBed and using Fake Classes.
Is it good practice to use a Mock with : any data type below?
If not I receive following errors, missing items/parameters.
I could use spyOn, but it requires TestBed, and I am trying to avoid getting rid of all executable-run time error, 'with injectable import not found' with testBed.

...ANSWER
Answered 2020-Dec-21 at 19:12You can use any, the only problem it brings - the loose of type safety, therefore if the signature of modifyLkDocumentDiscardReasonPost has been changed, for example it doesn't return promise anymore - then there's no typescript error.
If you want to mock classes and avoid losing the type safety you might consider usage of ng-mocks, it allows to create mock shapes and in the same time keeps type safety, so if someone changed the type - typescript would let know developers about that in mocks too.

I wrote a unit test for material check box. I used [(ngModule)] to bind check-box to the model. the first test case is ok, clicking on the checkbox will update the model however when I change the model in the next unit test, It does not happen. In other words, when I set enabled to true, the checked state does not change to true! How can I pass the last unit test? The code is uploaded to github

Answered 2020-Sep-22 at 13:08You most likely need a new reference to the DOM/HTML. checkbox refers to the old DOM before the fixture.detectChanges().

ANSWER
Answered 2020-Sep-14 at 22:09Since you're mapping over Docker's networking you can't just bind to the loopback interface, but to the main one, so you need to bind to 0.0.0.0 not localhost or 127.0.0.1.
That will permit "external" connections, as your main machine and the Docker virtual machine's "localhost" are two different things.
This should be as simple as using the --host flag:
QUESTION
I am using angular with ag-grid as per documentation.
I am facing 2 problems :
1. I wrote the actual code in my vscode but i am not able to successfully reproduce it in stackblitz.
2. My grid contains 10 columns each of width 200 , when i do a ng test --code-coverage on vscode , the tests run on chrome browser and i immediately expand it to full screen. All my tests pass. But when i resize my chrome to about 30% of screen or less and rerun my tests, it shows an error that some of the columns are not defined that is it shows length of the header array to be less than 10. And the test fails.
What i am trying to say is that when i reduce the window size it is like first 5 columns are defined and the rest are not.
Is there any reason for this to happen?
Also please help me in setting up the stackblitz for the same.
NOTE : I may not be able to show it as stackblitz is not properly working, however there is a console.log statement in the second test which is what i am referring to.
...ANSWER
Answered 2020-Aug-29 at 20:03If what you are testing is whether all of the columns actually appear in the DOM, then the problem is that by default, the grid virtualizes both rows and columns. That is, it only creates DOM nodes for rows and columns that are visible.
So, if your window is small enough that some of the columns are not visible in the grid's viewport, then those columns will not exist in the DOM. When you size the window larger to expose the previously missing columns (or scroll to reveal them), the DOM nodes are created at that time.
The quick fix is to turn column virtualization off (at least for the test).
