johnpapa ng-demos: variety of angular demos

Translations of this Angular style guide are maintained by the community and can be found here. Note that the names list and detail are arbitrary descriptive names for these components. There is no rule that says you have to use those. It could be HeroDetailComponent, HeroEditorComponent, or anything that is decriptive and consistent in our app. Many of my styles have been from the many pair programming sessions Ward Bell and I have had.

When manipulating the DOM directly, use a directive. If alternative ways can be used such as using CSS to set styles or the animation services, Angular templating, ngShow or ngHide, then use those instead. For example, if the directive simply hides and shows, use ngHide/ngShow. When calling a data service that returns a promise such as $http, return a promise in your calling function too.

All of the app’s code goes in a root folder named app. Each controller, service, module, view is in its own file. All 3rd party vendor scripts are stored in another root folder and not in the app folder. I didn’t write them and I don’t want them cluttering my app . $http is a service injection, not a module. You register modules dependencies in app.core (angular-animate, angular-sanitize…), and inject services, factories…

My most excellent friend Ward has helped influence the ultimate evolution of these guides. Demonstrates how to distribute an app across several modules, including handling the routing, testing, gulp automation and more. One component per file promotes easier unit testing and mocking. I think you should read all of them and make up your mind what approach is better for your project.

I personally prefer Gulp as I feel it is easier to read and write, but both are excellent. Client-side routing is important for creating a navigation flow between views and composing views that are made of many smaller templates and directives. Note that yasnippet categorizes snippets by major mode, https://topbitcoinnews.org/ and there are several Emacs major modes for editing Javascript code. The snippets are in js2-mode, and the other directories contain only a dotfile to reference them there. Use consistent names for all directives using camelCase. Use a short prefix to describe the area that the directives belong .

  • When creating a directive that makes sense as a stand-alone element, allow restrict E and optionally restrict A .
  • When using a module, avoid using a variable and instead use chaining with the getter syntax.
  • In other words, start small but keep in mind on where the app is heading down the road.

Use function declarations to hide implementation details. Keep your accessible members of the factory up top. Point those to function declarations that appears later in the file. I find that the Angular community is an incredible group who are passionate about sharing experiences. As such, Angular expert Todd Motto and I have collaborated on many styles and conventions.

John Papa’s Angular Style Guide Y165 Recommendation… what to inject in app.core module?

Right where you need them, in your case, dataservice. Use $inject to manually identify your route resolver dependencies for Angular components. Style Guides require experience building applications with the tools. Programming Tips Nobody has the equivalent massive experience with Angular 2, and thus the Angular 2 Style Guide is a work in progress. Place components that define the overall layout of the application in a folder named layout.

I’ve had input that has impacted this from Ward Bell, Dan Wahlin, Igor Minar, Jules Kremer, and others from the Angular team and Angular GDEs. Larger app running a fictitious event named «CodeCamper». All client side javascript using Angular for routing, animation, and basic CSS theming. Needs to review the security of your connection before proceeding. If you go to AngularJs’s site you end up creating a «Hello World» example with a non ideal file architecture. I generally start with 300ms and adjust until appropriate.

If you are looking for an opinionated style guide for syntax, conventions, and structuring Angular applications, then step right in. These styles are based on development experience with Angular, presentations, Pluralsight training courses and working in teams. I get asked a lot for style guides, how to get started once you learn the AngularJS basics, and what I recommend. This guide helps point in that direction using my guidelines. It’s is not important to follow someone else’s guidelines as much as it is to understand why people choose what they do.

You will gain so much more from talking to people online or in person, than from reading a guide that may or may not be up to date. I’m looking for any reading material or videos I can watch to get me pointed in the right direction. I feel learning React won’t be too bad, but I want to learn in a manner that is consistent to what is expected in the real world. I’ve done a few obvious google searches, but would like to hear feedback from some experience React developers.

You can learn more here at about how to contribute. Otherwise you will just spend days reading and thinking about guides without doing actual work. Unless you do use it you won’t see the best way to implement something by yourself moreover reasons behind the best practices.

I am careful to only release conventions that I feel are vetted and have worked based upon experience. So the underlying problem with releasing an entire style guide right now is that there is not a lot of experience to lean on for many things. But there is enough traction now where we can safely say the foundations can be agreed upon and published. So when I do make the style guide publicly available, it will contain those foundations.

Angular Style Guide by John Papa

// Add user-identifying info so service gets the right credit limit for this user. Place bindable members at the top of the controller, alphabetized, and not spread through the controller code. Use named functions instead of passing an anonymous function in as a callback. When using a module, avoid using a variable and instead use chaining with the getter syntax.

Feel free to grab it, clone it, or fork it. Instructions on running it are in its readme. The Angular style guide by John Papa is considered the definite resource for Angular developers. John’s guide is based on his own personal experiences working in team environments, making presentations and building training courses about Angular. Open an issue first to discuss potential changes/additions.

These are style guides there are no cold hard arguments for one in particular. They overlap on a lot of things that make sense, the rest is preference. Consistency is what’s important – pick one, or make your own, and stick to it.

Create small modules that encapsulate one responsibility. Use a decorator, at config time using the $provide service, on the $exceptionHandler service to perform custom actions when exceptions occur. When the above code is run through ng-annotate it will produce the following output with the $inject annotation and become minification-safe. Factories are singletons and return an object that contains the members of the service. Wrap Angular components in an Immediately Invoked Function Expression .

Any code that needs to run when an application starts should be declared in a factory, exposed via a function, and injected into the run block. Create folders named for the feature they represent. When a folder grows to contain more than 7 files, start to consider creating a folder for them.
