I made revision of API design course v4 from frontend masters. Code was written in node js with express js framework. Final app have server app listening on port 3001. Two unprotected routers to register(create new user) and sign in. All other routes defined within router with \api prefix. Router has protect middleware which ensures that user who is trying to communicate on /api/… routes holds valid token


Token is created for each user during registration. Jsonwebtoken library(JWT) provides means to combine user name, password and JWT_SECRET into unique token. Token is send in server response to signin POST request.


Course api is using postgresql database hosted via render.com. Each of cloud dbs have external URL string which can be used as DATABASE_URL environmental variable. Object relation model(ORM)- prisma is used to provide object oriented interface for relational SQL db. All data modeling is included within prisma.schema files. User may get access to current db records via studio interface – „npx prisma studio”.


Best regards

  fig 1.1 BehaviorSubject abstraction marble diagram       It is high time to write another part of angular basics revision. Last time i mentioned Subject object. It is also worth to describe other ‚special’ cases of Subject. The first is behavior subject. It is part of powerful tool for reactive programming called rxjs . When writing angular version of exchange app or mars-rover-photos app I was using behavior subject in following way. Start with declaring behavioral subject private field within your service. The following example ilustrates this step: private myDataSubject: BehaviorSubject<any> = new BehaviorSubject<any>( null );     it will declare new private field with myDataSubject name and BehaviorSubject type. The value within <> braces is called type parameter and is a part of TypeScript generic types. In this case it would describe the type of values emited by this subject. on the right side of the assignment statement we can see basic javas

Another subject from the set of 97 things that every programer should know is simplicity. The most important thing designing software is to provide client with the functionality tailored to their real needs. Managers dont care about tools applied to obtain requested outcome as long as it gets the job done quickly and satisfy the requieements. On the other hand developers mostly need challenge and constant growth. As a consequence nowadays applications tend to be over-engineered and stuffed with additional libraries, frameworks with tons of configuration. Today ive also watched a youtube video of primagean. It was a comment on article titled "Radical simplicity". It is a reason why id written previous paragraph. The article was about technical overhead that is tend to be introduced within the aplications recently. The one good thought was that nowadays applications are able to do more stuff. The main thought was to use the bare minimum and be careful about introducing new d

fig 1.1 angular application structure overview      Recently I have been re-writing one of my side projects using another js framework. Originaly written in react, after several days and long hours of scrolling and prompting it was re-shaped to Angular version . In this blog post I want to summarize the stuff I have learned about javascript frontend framework developed by Google . There are only class components. No function component nor hooks available in angular. Moreover it requires developer to use typescript straightaway without support for vanillla js which make it less available for beginners. Angular has no dedicated syntax such as jsx/tsx which enables to combine template, controller and styles within single file. It divides the responsibilities to separate view-template.html file and component.ts file which contains logic. It is a good moment to mention that re-renders of the ui uses diferent technique under the hood. Angular utilizes incremental DOM mechanism a
