Use SVG images to minimize file/download size, maintain image sharpness, react to changes in screen size and devices. I have not been a fan of SVGs in the past. Editing them requires specialized knowledge (yes, Inkscape is specialised for me), editing them online has been flaky, and availability of SVGs for stock images have not been good.

I had to create a mobile app for one of the data driven applications that I recently developed. Cordova has proven to be an excellent choice to reuse my existing code and make life easier for everyone. Nature of the web app - Enable users to create and track specialised electronic devices Track customers who buy these specialised devices and deploy them at their site Track usage of deployed devices Track issues and manage resolution process Enable users to create charts out of device usage The app is hybrid of technologies but the web app was mainly developed using Javascript in the backend.

Date validation is not common for input fields since dates are ‘picked’ from a date picker rather than typed in. But it has its uses - for e.g. if you are enabling dates in a list view with copy/paste ability, or validating dates sent by a third party system. Let us look at a couple of ways in which you can validate dates.

There are two ways to conditionally show or hide UI elements in Vue - v-show and v-if. Learn which option to use where. v-show Use v-show to show an element on the UI based on given condition. The element is present in the DOM, but will have class set to display: none.

Vue supports two-way binding through the excellent v-model directive, and one-way binding using a :value= syntax. Both have their uses within a Vue component. There are good enough reasons to use one over the other. First, let’s look at an example of two-way binding - 1 2 3 4 5 6 7 8 9 10 11 <template> <input v-model="message" /> </template> <script> export default { data() { return { message: "hello" }; }, }; </script> v-model is a short form of v-bind.

There are three main ways to store variables and/or react to variable changes in Vue components. data computed Watch for changes in watcher So, how to decide when to use what? (that is 3-in-1 question, I outwit myself) Although these sections look similar, they serve different functions. Evaluate the variables against the following considerations when you are in doubt.

Vue provides one excellent way and three other alternative ways of getting your components to work together to form one beautiful, seamless application. Let us look at them one by one :) 1. Vuex Yesterday we talked about Vuex and how we (try to) manage vuex variables and local variables in a Vue component.

Vuex is quite a powerful way of storing variables and sharing them across components, but where do you draw the line? Which variables do you store locally and which of them are shifted to Vuex store? This is the advise I often come across - Get your variables in store; keep component clean and consider future reuse Don’t overdo Vuex.

Vue allows us to build out infinite blocks of components that can work together or build on top of another to provide UIs of increasing sophistication. You may have a page or view that loads dozens of components including fields, tabs, charts and so on, and the loading of such components is automatically taken care by Vue.

Search in Vuetify data tables is just beautiful. Define a data table and a search is readily available for you. What else can a human ask for? In fact, data tables were the single biggest reason for me to choose Vuetify about an year back. My long term association with data-driven application means that I am ever-so-dependent on the data table functionality.

Let us see how we can easily accumulate requests when user types in a search (or auto-complete) fields and collate them in one go. When implementing the ‘instant search’ fields in Vue, the cycle of events is pretty standard - User keys in characters System keeps getting those characters and sending them to the server for processing System reacts to changes from server and displays search results The same cycle repeats for fields include auto-complete that take user action and return stuff from server.

Vue filters provide an excellent way to format data on the UI. Define Vue filters using a filter: block in single file components, or use global filters. Consider the following use cases - Purchase date is stored in yyyy-mm-dd in DB, but you have to display dd-mm-yyyy format Cost data needs to be displayed in currency of user’s locale Apply separators in bill number for better readability These and many more are easily accomplished in Vue filters.

You find forms everywhere in a data-driven application. Forms, as a rule, need some validation on the client-side to nudge users to fill in data in line with what we want. These validation are easy to implement in Vue. Consider an example that includes Vuetify for styling the UI -
