12 Tips and Tricks to Improve Your Vue Projects

When starting with a new framework it might be hard to get to know all the things about it. Vue.js is an amazing framework that is powerful and easy to learn. Today I want to share with you a few tips and tricks that can be useful for your Vue projects.

1. $createElement

It is not documented in Vue documentation, but each Vue instance has access to $createElement method, which can create and return virtual nodes. You could, for example, use it if you would like to prepare Markup in your methods and then pass it to ‘v-html’ directive. You also have access to this method in functional components, which receive it as the first parameter in the render function.

2. Watch/Immediate

Imagine you have a news application and you have a component to display an article. This component could fetch an article for a route like “”. Usually, you would initialize an API call in “created” life-cycle hook to fetch article details.

You also have next and previous article functionality, which will let users go to other articles. When a user changes an article, nothing would happen, so that’s why we need a watcher to fetch data for a new article.

However, in this case we are calling ‘fetchArticle’ method in both “created” hook and watcher. Fortunately, we can change that by using ‘immediate’ property for the watcher.

This will result in the handler being invoked immediately when the component is created. Be aware, though, that immediate watcher handlers will be run just after anything in the ‘created’ hook. So, if for any reason you need to fetch data before something else happens in the created hook, then you will need to have it twice and resign from the ‘immediate’ prop.

3. Reusing Component for the Same Route

In some instances, you might have a few different routes that are using the same component. However, by default if you change between those routes, the component will not be re-rendered. This is a normal thing as Vue is reusing the already existing component for performance reasons. However, if you want the component to be re-created, you can provide “:key” prop to the “” component.

4. $on(‘hook:’)

This is another nicety which I think is still is not documented yet. Often if you are using a third-party plugin or need to add a custom event listener, you first define it in created or mounted hook and then remove it in “beforeDestroy” hook. It is a very important to clear out event listeners, so your code doesn’t cause memory leaks. Sometimes plugins might have a ‘destroy’ method.

With use of $on(‘hook:) you can avoid a definition of another life-cycle hook.

5. Custom v-model

By default, v-model is the syntactic sugar feature over “@input” event listener and “:value” prop. Did you know that you can actually specify what event and value prop should be used? You can easily do that by specifying ‘model’ property in your Vue component.

6. Prop Validation

Most of the time you might be fine with validating your props by providing String, Object, etc. However, props can also be validated with use of custom validators. For instance, if you expect to get a string that should match any string from a list of string, then you can do something like that:

7. Delimiters

Vue is using double curly brackets “{{ }}” for expressions in HTML files and templates. Unfortunately, it can collide with other engines — for example if you are using Jinja templates, which also do use double curly braces. Fortunately, Vue offers a way to change delimiters used in your templates, so you could use double brackets “[[ ]]” instead.

8. Functional Components

This is not really a tip, but something you should be using in your projects. Usually, if you have a component that is only accepting props, rendering markup and not using anything from Vue instance like life-cycle hooks, computed properties, methods, or data model, then you can provide the “functional” option and set it to true to indicate that this component should not have Vue instance. You can also do it by providing ‘functional’ prop on the template.

The benefit of functional components is they are much cheaper to re-render than stateful components. However, be careful when you wrap stateful components with functional components, as functional components are always re-rendered and will cause stateful components to be re-rendered as well.

9. JSX

Something for React lovers. Since release of Vue CLI 3, JSX is supported by default in Vue, and if your project is on an earlier version of Vue CLI, then you can use babel-plugin-transform-vue-jsx plugin. I often use it, especially in functional components since writing pure render functions can be quite tedious.

10. Snippets

Snippets can be a real time saver as you can write code quickly. For instance, in Visual Studio Code with these two snippets configured, I can create base code for stateful and functional components by typing “vtemp” or “vfcomp”.

11. Vetur

Not sure about other code editors, but if you are using Visual Studio Code, then you should certainly check out Vetur plugin. It provides quite useful features out of the box, like syntax-highlighting, linting and error checking, formatting, emmet, etc.

12. Automatic Registration of Base Components

Most of the time there are components in a project which are used over and over and importing them in almost every component is quite tedious. Therefore, as they are used almost everywhere, they could be imported and registered just once, globally. You can think of them as ‘Base’ components of your application. This script can register all base components automatically.

Next, import this method in your main.js files and initialize it.

Top Android Projects with Source Code

Android Projects with Source Code – Your entry pass into the world of Android

Hello Everyone, welcome to this article, which is going to be really important to all those who’re in dilemma for their projects and the project submissions. This article is also going to help you if you’re an enthusiast looking forward to explore and enhance your Android skills. The reason is that we’re here to provide you the best ideas of Android Project with source code that you can choose as per your choice.

These project ideas are simple suggestions to help you deal with the difficulty of choosing the correct projects. In this article, we’ll see the project ideas from beginners level and later we’ll move on to intermediate to advance.

top android projects with source code

Android Projects with Source Code

Before working on real-time projects, it is recommended to create a sample hello world project in android studio and get a flavor of project creation as well as execution: Create your first android project

Android Projects for beginners

1. Calculator

build a simple calculator app in android studio source code

Android Project: A calculator will be an easy application if you have just learned Android and coding for Java. This Application will simply take the input values and the operation to be performed from the users. After taking the input it’ll return the results to them on the screen. This is a really easy application and doesn’t need use of any particular package.

To make a calculator you’d need Android IDE, Kotlin/Java for coding, and for layout of your application, you’d need XML or JSON. For this, coding would be the same as that in any language, but in the form of an application. Not to forget creating a calculator initially will increase your logical thinking.

Once the user installs the calculator, they’re ready to use it even without the internet. They’ll enter the values, and the application will show them the value after performing the given operations on the entered operands.

Source Code: Simple Calculator Project

2. A Reminder App

Android Project: This is a good project for beginners. A Reminder App can help you set reminders for different events that you have throughout the day. It’ll help you stay updated with all your tasks for the day. It can be useful for all those who are not so good at organizing their plans and forget easily. This would be a simple application just whose task would be just to remind you of something at a particular time.

To make a Reminder App you need to code in Kotlin/Java and design the layout using XML or JSON. For the functionality of the app, you’d need to make use of AlarmManager Class and Notifications in Android.

In this, the user would be able to set reminders and time in the application. Users can schedule reminders that would remind them to drink water again and again throughout the day. Or to remind them of their medications.

3. Quiz Application

Android Project: Another beginner’s level project Idea can be a Quiz Application in android. Here you can provide the users with Quiz on various general knowledge topics. These practices will ensure that you’re able to set the layouts properly and slowly increase your pace of learning the Android application development. In this you’ll learn to use various Layout components at the same time understanding them better.

To make a quiz application you’ll need to code in Java and set layouts using xml or java whichever you prefer. You can also use JSON for the layouts whichever preferable.

In the app, questions would be asked and answers would be shown as multiple choices. The user selects the answer and gets shown on the screen if the answers are correct. In the end the final marks would be shown to the users.

4. Simple Tic-Tac-Toe

android project tic tac toe game app

Android Project: Tic-Tac-Toe is a nice game, I guess most of you all are well aware of it. This will be a game for two players. In this android game, users would be putting X and O in the given 9 parts of a box one by one. The first player to arrange X or O in an adjacent line of three wins.

To build this game, you’d need Java and XML for Android Studio. And simply apply the logic on that. This game will have a set of three matches. So, it’ll also have a scoreboard. This scoreboard will show the final result at the end of one complete set.

Upon entering the game they’ll enter their names. And that’s when the game begins. They’ll touch one of the empty boxes present there and get their turn one by one. At the end of the game, there would be a winner declared.

Source Code: Tic Tac Toe Game Project

5. Stopwatch

Android Project: A stopwatch is another simple android project idea that will work the same as a normal handheld timepiece that measures the time elapsed between its activation and deactivation. This application will have three buttons that are: start, stop, and hold.

This application would need to use Java and XML. For this application, we need to set the timer properly as it is initially set to milliseconds, and that should be converted to minutes and then hours properly. The users can use this application and all they’d need to do is, start the stopwatch and then stop it when they are done. They can also pause the timer and continue it again when they like.

6. To Do App

Android Project: This is another very simple project idea for you as a beginner. This application as the name suggests will be a To-Do list holding app. It’ll store the users schedules and their upcoming meetings or events. In this application, users will be enabled to write their important notes as well. To make it safe, provide a login page before the user can access it.

So, this app will have a login page, sign-up page, logout system, and the area to write their tasks, events, or important notes. You can build it in android studio using Java and XML at ease. Using XML you can build the user interface as user-friendly as you can. And to store the users’ data, you can use SQLite enabling the users to even delete the data permanently.

Now for users, they will sign up and get access to the write section. Here the users can note down the things and store them permanently. Users can also alter the data or delete them. Finally, they can logout and also, login again and again whenever they like.

7. Roman to decimal converter

Android Project: This app is aimed at the conversion of Roman numbers to their significant decimal number. It’ll help to check the meaning of the roman numbers. Moreover, it will be easy to develop and will help you get your hands on coding and Android.

You need to use Android Studio, Java for coding and XML for interface. The application will take input from the users and convert them to decimal. Once it converts the Roman no. into decimal, it will show the results on the screen.

The users are supposed to just enter the Roman Number and they’ll get the decimal values on the screen. This can be a good android project for final year students.

8. Virtual Dice Roller

Android Project: Well, coming to this part that is Virtual Dice or a random no. generator. It is another simple but interesting app for computer science students. The only task that it would need to do would be to generate a number randomly. This can help people who’re often confused between two or more things.

Using a simple random number generator you can actually create something as good as this. All you’d need to do is get you hands-on OnClick listeners. And a good layout would be cherry on the cake.

The user’s task would be to set the range of the numbers and then click on the roll button. And the app will show them a randomly generated number. Isn’t it interesting ? Try soon!

9. A Scientific Calculator App

Android Project: This application is very important for you as a beginner as it will let you use your logical thinking and improve your programming skills. This is a scientific calculator that will help the users to do various calculations at ease.

To make this application you’d need to use Android Studio. Here you’d need to use arithmetic logics for the calculations. The user would need to give input to the application that will be in terms of numbers. After that, the user will give the operator as an input. Then the Application will calculate and generate the result on the user screen.

10. SMS App

Android Project: An SMS app is another easy but effective idea. It will let you send the SMS to various no. just in the same way as you use the default messaging application in your phone. This project will help you with better understanding of SMSManager in Android.

For this application, you would need to implement Java class SMSManager in Android. For the Layout you can use XML or JSON. Implementing SMSManager into the app is an easy task, so you would love this.

The user would be provided with the facility to text to whichever number they wish also, they’d be able to choose the numbers from the contact list. Another thing would be the Textbox, where they’ll enter their message. Once the message is entered they can happily click on the send button.

8 Popular Websites That Use The Vue.JS Framework

In this article, we are going to list out the most popular websites using Vue JS as their frontend framework.

Vue JS is one of those elite progressive JavaScript frameworks that has huge demand in the web development industry. Many popular websites are developed using Vue in their frontend development because of its imperative features.

This framework was created by Evan You and still it is maintained by his private team members. Vue is of course an open-source framework which is based on MVVM concept (Model-view view-Model) and used extensively in building sublime user-interfaces and also considered a prime choice for developing single-page heavy applications.

Released in February 2014, Vue JS has gained 64,828 stars on Github, making it very popular in recent times.

Evan used Angular JS on many operations while working for Google and integrated many features in Vue to cover the flaws of Angular.

“I figured, what if I could just extract the part that I really liked about Angular and build something really lightweight." - Evan You

10 Writing steps to create a good project brief - Mobile app development

Developing a mobile application can often be more challenging than it seems at first glance. Whether you’re a developer, UI designer, project lead or CEO of a mobile-based startup, writing good project briefs prior to development is pivotal. According to Tech Jury, 87% of smartphone users spend time exclusively on mobile apps, with 18-24-year-olds spending 66% of total digital time on mobile apps. Of that, 89% of the time is spent on just 18 apps depending on individual users’ preferences, making proper app planning crucial for success.

Today’s audiences know what they want and don’t want in their mobile apps, encouraging teams to carefully write their project plans before they approach development. But how do you properly write a mobile app development brief without sacrificing your vision and staying within the initial budget? Why should you do so in the first place? Let’s discuss that and more in greater detail.

Why a Good Mobile App Project Brief Matters?


It’s worth discussing the significance of mobile app project briefs before we tackle the writing process itself. In practice, a project brief is used as a reference tool for developers to remain focused on the client’s deliverables. Approaching the development process without written and approved documentation can lead to drastic, last-minute changes, misunderstanding, as well as a loss of resources and brand reputation.

For example, developing a mobile app that filters restaurants based on food type, such as Happy Cow, means that developers should stay focused on it. Knowing that such and such features, UI elements, and API are necessary will help team members collaborate better in order to meet certain expectations. Whether you develop an app under your brand’s banner or outsource coding and design services to would-be clients, briefs can provide you with several benefits:

  • Clarity on what your mobile app project “is” and “isn’t” early in development
  • Point of reference for developers, project leads, and clients throughout the cycle
  • Smart allocation of available time and resources based on objective development criteria
  • Streamlined project data storage for further app updates and iterations

Writing Steps to Create a Good Mobile App Project Brief


1. Establish the “You” Behind the App

Depending on how “open” your project is to the public, you will want to write a detailed section about who the developers are. Elements such as company name, address, project lead, project title, as well as contact information, should be included in this introductory segment. Regardless of whether you build an in-house app or outsource developers to a client, this section is used for easy document storage and access.
