angular-university / rxjs-course Goto Github PK

For some time GitHub checks the file package-lock.json to detect vulnerabilities - this course as it exists today results with the following diagnose (as a consequence of running npm install:

found 39 vulnerabilities (27 low, 3 moderate, 9 high) in 24102 scanned packages
  run `npm audit fix` to fix 25 of them.
  14 vulnerabilities require semver-major dependency updates.

I am proposing to update the file `package.json' to be:

{
  "name": "rxjs-course",
  "version": "0.0.0",
  "license": "MIT",
  "scripts": {
    "ng": "ng",

    "ts-node": "~3.2.0",
    "tslint": "~5.7.0",
    "typescript": "3.1.3"
  }
}

After running the npm install with this package.json, run the following:

npm update fsevents --depth 6
 npm update request --depth 3
 npm update fill-range --depth 7

This results with clean build - 0 vulnerabilities

When trying to import a function or whatever from the util.ts file located under src/app/common/util.ts. Normally this should work, but it doesnt :(. The auto completition works for other things (angular or rxjs), but when I try to import a global interface or function, I can't import it. The only way is by adding the import and writing the path by hand.

The home.component.ts file

The utils.ts file

I did a git clone from the repository, so didn't change all the tsconfig files.

I thought that my typescript wasn't updated, so I installed the latest version, but that wasn't the solution.

Thank you for your help.

Since the latest commit moving the project to Angular 9, ng serve that is executed by the start script in package.json has been failing. I am working from the 1-operators branch. The error is coming from CourseComponent. The lessons$ and course$ observables are missing in the controller but are referenced in the view.

In course-dialog component, save() function is missing in component code. This can be solved either by

1. Adding empty implementation of save() function in component code or
2. Removing save function binding of click event in template.

I am trying to run this app in visual studio code but I am getting "this site cannot be reached" when using port 9000,

Config:
Windows 10 Enterprise, build 19044.1645

Angular CLI: 13.0.4
Node: 16.14.2
Package Manager: npm 6.14.5
OS: win32 x64

Angular: 13.0.3
... animations, cdk, common, compiler, compiler-cli, core, forms
... language-service, material, material-moment-adapter
... platform-browser, platform-browser-dynamic, router

@angular-devkit/architect (0.1300.4)
@angular-devkit/build-angular (13.0.4)
@angular-devkit/core (13.0.4)
@angular-devkit/schematics (13.0.4)
@angular/cli (13.0.4)
@schematics/angular (13.0.4)
rxjs (6.5.4)
typescript (4.4.4)

When I find all the instances of port 9000 and change it to 4200, the application runs but I cannot hit the courses api. I get a 404 error. Also, when I run it under port 9000 using "npm start", the command line shows:

** Angular Live Development Server is listening on localhost:4200, open your browser on http://localhost:4200/ **

Any help is appreciated.

In master branch and 1-operators branch.

Unfortunately, a new version of node and angular make it hard to run server and client. in order to work just change the package.json file and you will be good to go.
line code 7 and 8 inside package.json
"start": "ng serve --proxy-config ./proxy.json", "server": "ts-node -P ./server/server.tsconfig.json ./server/server.ts",
for server -> npm run server
for client -> npm start
