Difference between Asyncdata vs Fetch

What is the exact difference between fetch and async data. The official documentation says the following:

asyncData
You may want to fetch data and render it on the server-side. Nuxt.js adds an asyncData method that lets you handle async operations before setting the component data.
asyncData is called every time before loading the component (only for page components). It can be called from the server-side or before navigating to the corresponding route. This method receives the context object as the first argument, you can use it to fetch some data and return the component data.
Fetch
The fetch method is used to fill the store before rendering the page, it's like the asyncData method except it doesn't set the component data. The fetch method, if set, is called every time before loading the component (only for page components). It can be called from the server-side or before navigating to the corresponding route.
The fetch method receives the context object as the first argument, we can use it to fetch some data and fill the store. To make the fetch method asynchronous, return a Promise, nuxt.js will wait for the promise to be resolved before rendering the component.

Fetch is been used to fill the store with data? But in asyncData is this also possible to commit trough a store? I don't understand why there are two methods for.

Both methods are running server-side on the initial load, after that when you navigate through the applicatie it runs client side.

Can someone explain me the advantage of use these methods above the other?

Thanks for help.

Let me re-iterate few points as a pretext to what i’m going to say

  • asyncData can set component level objects and access vuex store
  • fetch cannot set component level objects but has access to vuex store
  • Both asyncData & fetch will be triggered in server side during initial load
  • After initial load, asyncData and fetch will be triggered when the corresponding page routes are invoked

1) if your design is

  • asyncData can set component level objects and access vuex store
  • fetch cannot set component level objects but has access to vuex store
  • Both asyncData & fetch will be triggered in server side during initial load
  • After initial load, asyncData and fetch will be triggered when the corresponding page routes are invoked

then use fetch

2) if your design is

  • asyncData can set component level objects and access vuex store
  • fetch cannot set component level objects but has access to vuex store
  • Both asyncData & fetch will be triggered in server side during initial load
  • After initial load, asyncData and fetch will be triggered when the corresponding page routes are invoked

then use asyncData

Can someone explain me the advantage of use these methods above the other?
i don’t see any drawbacks in using asyncData or fetch

Choosing asyncData or fetch totally depends on your architecture

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

Lean vs Agile vs Waterfall | What is Lean | Difference between Waterfall and Agile

In this video you will learn the difference between waterfall and agile model, what is lean, lean vs agile vs waterfall differences in detail.

Why DevOps is important?

DevOps implementation is going through the roof with most of the largest software organizations around the world invested heavily in its implementation. The core values of devops is effectively based on the Agile Manifesto but with one slight change which moves the focus from creating a working software to one that is more interested in the end-to-end software service mechanism and delivery.

PWA vs Native App: Which Is Better Option In 2021?

Every year, the world is expanding with the launch of new smartphones and other gadgets available in the market. According to Statista, more than 50% of the population will be using smartphones by the end of 2021.

Hence, businesses worldwide have understood the importance of smartphones and are joining the mobile industry by launching native apps.

Apart from native apps, progressive web apps is another technology that is gaining a lot of attention among businesses. Moreover, various leading companies worldwide have openly accepted PWA and built progressive web apps.

Now, the question arises, how is PWA different from the native apps? Read More

CockroachDB vs (MySQL, PostgreSQL, MongoDB & Cassandra)

An introduction to CockroachDB

If you are an entrepreneur or an enterprise IT leader, then you need to plan the technology stack for your software development project. You need to choose the right database for your project. If you are developing a heavy-duty transaction processing system or a high-demand analytics system, you will likely use an RDBMS (Relational Database Management System). You can choose one from several popular RDBMSs.

However, do you want an assurance that your data in an RDBMS will survive even large-scale failures in application systems and servers? This narrows the choice. This is where CockroachDB becomes important. This relatively new RDBMS offers a high degree of survivability to your data. In this article, we review CockroachDB and its features. We assess its pros and cons. Subsequently, we review its use cases. Finally, we compare CockroachDB with some of the popular databases. Read on.
