  • Once both teams have a agreement, the respective teams can go off and start their work.Fake EndpointsIn order for the UI to start progression while the backend is still in works, you need some way to mock the response from the data.
  • This requires the front-end users to run the backend while its very unstable, lead time for the back-end developers to build this out and they maintain it making it difficult to get different data for your testingFrontend API functions dont actually call any backend but just hardcode the data in….
  • When you run your application in dev mode, instead of calling out the the API endpoint, the In Memory DB will intercept it instead and return this data for us.You can see a end-to-end demo of this here: do we improve quality withmocking?If we look at the in memory db…
  • This is a essential tool in any programmers toolbar.Putting it alltogetherHaving the ability to quickly make fake services returning random data gives us maximum efficiency to develop quality code quickly.
  • We no longer have to lag behind backend teams, wait for fake endpoints or hardcode data in our services with tools and methods like these.

  • Version Stamping your App with the AngularCLIWhen building applications, you typically need some way to show the build version somewhere in your app.
  • Lets write a script that will get the Git hash and the version from the package.json.
  • This looks something like this:Lets hook this script up to run on postinstall of our application.
  • So navigate to your package.json and add this line to the scripts:{ scripts: { postinstall: node version.js }}Now anytime we run npm i our app version will get updated for us.This script will create a file in our environments folder called version.ts.
  • Now we have our versions showing up in our app.

  • We would instead import the operators like this: – – and then to use the operator we would need to use the new method to run any operators that we want on the observable, like this: – – Instead of chaining observables together, now we just call the method on…
  • To apply multiple operators, you can just add additional operators to the method: – – You can also use this new method with the commonly used operator by importing the operator like this: – – and then using it as follows: – – But, for now at least, if you…
