- We can say that it’s a new type of JS library, offering a new approach to build/update a View.
- It creates a virtual DOM to track the changes when the application state is updated and uses the virtual DOM to update only those parts of a page which have been changed.
- In the upcoming article, I will explain more about virtual DOM using programming example along with the graphical view.

- After Apollo takes care of fetching and mapping props to query parameters, query component uses âfunction-as-a-childâ approach to expose a child-independent API with injected data.Comparing to the standard approach were you add a graphql wrapper to your higher-order components, query components have a set of advantages:Testability.
- Query Components abstracts out your data management layer so you can focus on business logic and change underlying implementation if needed.Once a Query Component is defined, it can be used as an any other component in your application:A nice side effect of decoupling higher-order components into Query Components is minimizing…
- If the data management layer grows, it wonât affect presenter components unless they have to reflect new data properties.Mutations with Query ComponentsMutations are not that straightforward as queries.
- For example:Therefore, you can use this component in a similar way:So the concept is the same: Query Component receives a bunch of props that are later on used as parameters for the mutation query.Testing Query Components like a ProÂ đHow to test Query Components?When it comes to testing, Apollo-based components have…
- In other words, we check if given data.x complies to the shape of the mock that was passed to the fake client during initialization.And the last, but not least: query component should call a children function with the data, pulled from Apollo.
A couple of months ago, we started to use Apollo Client (+React Native) at Werkspot. From the very beginning, Apollo overwhelmed us by the simplicity and flexibility it provides. It inspired us to…

- With components, it has started to make more sense to include styling inline within a component like so:source: www.styled-components.comWhy InlineÂ Styling?You may be thinking to yourself, isnât inline styling bad practice?
- In the case of components though, inline styling has many advantages over vanilla CSS styling.
- Acording to Radiumâs website (another tool for inline styling) the benefits of using inline styling with components are:Scoped styles without selectors (styles are on component itself)Avoids specificity conflicts (two style definitions for one element)Source order independence (doesnât rely on the order files are imported)Dead code elimination (no unused classes as in CSS)Highly expressive (easier to read JSX)Original using styled-componentsâ cool.
- extend“ syntax.Styling with styled-componentsResulting WebpageFinishing UpInline styling of components is a powerful option to consider when building out user interfaces with React.
- There is a lot more that styled-components is capable of and I recommend looking through there tutorials and guides to get a better understanding of how awesome inline styling of your components can be!
Traditional styling of websites relies on having an external stylesheet with CSS. This tradition has been challenged with the advent of React and component based UI design. With components, it has…

- Wouldn’t it be great to be able to go back and look at the exact state of the application at the time of the crash and even the actions that led up to the crash?
- You would have to spread these things all over your application to catch your store at different phases of change.
- When you are working on larger apps however, there are advantages to having a single definition point.
- Let’s see how that may look:You can see above that we have combined 3 middleware:Our new custom loggerRedux Thunk for handling asynch callsRouterMiddleware that captures and redirects actions to your historyYou can combine middleware and they have no need to know about the ‘ware that proceeds or follows them.
- The moment between the Action and the Reducer is a critical exchange and using middleware to cleanly log state can improve the overall quality of your app.
I have written previously about REDUX and some of its features, if you are interested in a more general introduction, please check out the post below. Implementing this FLUX-style architecture has…

- Using a single language on the client and server allows for many advantages in today’s world, but there are also some pitfalls that need to be considered.
- In this talk we will cover:
• What does server side render of JS look like
• How is it possible to use the same language and frameworks in client and server side code
• What benefits can be gained by using a common language and framework.
- The goodies it brings — abstract and concrete classes, types, interface, enums are hard to resist.As we started on the development of the app, I thought it would be a good idea to put our learnings here in a series as it not only will help us document our tasks but would also help other react-native learners and developers.In this series, we will document step-by-step each task that we work on during the development of this app, right from the initial project set-up to its final implementation and release to the app store.What app we are going to developThe app we would be developing would be a simple photo albums app, where user can create an album and add photos to its from his/her mobile.Tech-stack to be usedUI using react-native + TypescriptStorage — Azure DocumentDBREST API using node.js, Azure DocumentDB Node APIAuthentication — oAuth (Facebook and Google)Targeted platformsIn its first version, we are planning to target only Android platform simply because couple of us in the team don’t own a Mac Book and apple doesn’t allow to develop iOS apps from any other operating system.Github RepoOur LimitationsWe are all learners of react/react-native, also this being a side project that we all will work on in our spare time, we are anticipating the project to go on a bit slow pace.Functional Testing — we don’t have a QE Automation expert in our team yet, so for most of its part Functional testing would be manual3.
- Environment — for the UI app, we will use emulators on our local system to test our code.
- Being a mobile app, it would be released to Android Playstore and thus we don’t need to maintain any servers for the UI app4.
- So stay tuned, more stories to come soonInterested in joining us in this wonderful journey?we’ll be glad to have you in our team, pls email to us at firstname.lastname@example.org with a little bit about yourself
Couple of weeks back, I and some of my friends, started on a side/hobby project to learn reactJS. We decided on developing a mobile app with react-native just because the idea of developing a native…

- You have the limited developers team with their skills and limited time for work.
- People around want us to use the newest technologies available to us, right after they have been created.
- We leave off working on our projects not written with React / ES6 / Webpack (or name another new technology) just because it’s not cool that they were written not with it.
- New technology is not always a good thing.
- I don’t mean that we don’t have to move on and bring new technologies into the development of our products.
“If you are a front-end developer and you still don’t use React in your projects, you might be a bad front-end developer. You don’t use ES6 either, do you? Too bad for you then. Maybe Webpack? No…
