For a long time, some frontend Javascript frameworks have helped you with one or two styles of Apps, but Quasar is an amazing new VueJS framework that allows you to build Single Page Apps (SPA), Server-side Rendered Apps (SSR), Progressive Web Apps (PWA), Mobile Apps (Android and IOS) through Cordova as well as Multi-platform Desktop Apps using Electron. With the Quasar CLI, you can quickly start a project, and have a single code base that can output multiple formats, as needed. Come to this session and find out how. Presented at Into the Box 2019

3. Fact: Most of us work on existing apps or legacy
apps
● Very few people get to work on Greenfield Apps
● We have to maintain the apps we have given to us
● We might have yui, moo tools prototype jquery & a few
more in real legacy app

4. Fact: We can’t jump on the bandwagon of the latest
and greatest javascript framework as they get
released weekly
● There are lots of Javascript plugins, libraries and frameworks
out there
● It felt like there was one released a week for a while
● It has calmed down, but still lots of options, can feel
overwhelming
● There are libraries, Frameworks and ways of life, not all will
work with your app

5. Q: What are some of the new javascript
frameworks?

6. Q: How does VueJS fit into the javascript
landscape?
THERE CAN BE ONLY ONE

7. Q: How does VueJS fit into the javascript
landscape?
Just kidding

8. Q: How does VueJS fit into the javascript
landscape?
Comparison ( Vue biased possibly )
https://vuejs.org/v2/guide/comparison.html
● VueJS - 115k stars on github - https://github.com/vuejs/vue
● React - 112k stars on github - https://github.com/facebook/react
● AngularJS (1) - 59k stars on github - https://github.com/angular/angular.js
● Angular (2,3,4,5,6) - 39k stars on github - https://github.com/angular/angular
● Ember - 20k stars on github - https://github.com/emberjs/ember.js/
● Knockout, Polymer, Riot

9. Q: How does VueJS fit into the javascript
landscape?
Big Players share the same big wins
● Virtual Dom for better UI performance
○ Only update changes not everything
● Reactive and composable components
○ You change the data, the Framework changes the UI

10. Q: How does VueJS fit into the javascript
landscape?
Why VueJS?
● Stable Progressive framework, with sponsors and solid community backing.
● Easy to learn and understand ( CFML Dev friendly concepts )
● Simple and Flexible - Does not require a build system
● Awesome Documentation!!!
● Lightweight ( 20-30kb )
● Great for simple components or full complex applications
● Official support for State Management ( Vuex ) and Routing ( Vue Router )
● Great Dev Tools and CLI tools and IDE Tools / Plugins

11. Q: Why do we want to add VueJS into our existing
apps?
● Easy to get started
● Easy to learn
● Easy to get value
● Easy to integrate

● Easy to find documentation

12. Q: Why do we want to add VueJS into our existing
apps?
Extremely Flexible
Most frameworks make you use their build system, their templates, and jump
through so many hoops.
● You can just include the library/core and use it where you need it
<script src="https://cdn.jsdelivr.net/npm/vue@2.5.17/dist/vue.js"></script>
● Angular 1 was like that
● Angular 2,3,4,5 etc and React is not really like that
○ All or nothing approach essentially

13. Q: Why do we want to add VueJS into our existing
apps?
Component Based ( if you want to )
● Abstract away the logic and display code
● Compose your Applications with smaller pieces
● Easier reuse and code sharing
● Lots of great components available
https://github.com/vuejs/awesome-vue

14. Q: Why do we want to add VueJS into our existing
apps?
If you want to, you can:
● Build a full Single Page App ( SPA ) App
○ Including Server Side Rendering for additional speed and SEO benefits
● Build and Release Desktop apps
○ Windows and Mac with Electron
● Build and Release Mobile Apps
○ IOS and Android with Cordova
○ Vue Native ( similar to React Native )

15. Q: How can we use some of the new technology in
our existing apps?
● Better form elements
● Better UI/UX in general
● Form Validation - more flexible than CFInput
● Data tables - Search, Pagination Sorting, Computing powered by ColdFusion
APIs
● SPA, Desktop and Mobile apps powered by ColdFusion APIs

30. Demo: jQuery vs VueJS DOM Manipulation
Pesticide Labels selection list for CSTC Safety
This company is a safety training company. When they do Pesticide trainings, they
need to select the pesticides the company works with. This little tool helps them
select which pesticides they need in their documentation. As this list has grown,
the responsiveness has dropped, dramatically.
We’re going to test hiding 3500 table rows and then showing them again in jQuery
vs VueJS.

Note: I use this in Quasar Framework

37. Demo: Datatable
Pros:
Lots of options out there
Cons:
Most of them require CSS to make them look good, so you might have to get a
CSS compatible with your existing styles.

40. The next step in VueJS Apps

41. What is Quasar?
Quasar (pronounced /ˈkweɪ.zɑɹ/) is an MIT licensed open-source Vue.js based
framework, which allows you as a web developer to quickly create responsive++
websites/apps in many flavours:
● SPAs (Single Page App)
● SSR (Server-side Rendered App) (+ optional PWA client takeover)
● PWAs (Progressive Web App)
● Mobile Apps (Android, iOS, …) through Apache Cordova
● Multi-platform Desktop Apps (using Electron)

42. What is Quasar?
● Quasar’s motto is: write code once and simultaneously deploy it as a
website, a Mobile App and/or an Electron App. Yes, one codebase for all of
them, helping you develop an app in record time by using a state of the art
CLI and backed by best-practice, blazing fast Quasar web components.
● When using Quasar, you won’t need additional heavy libraries like Hammerjs,
Momentjs or Bootstrap. It’s got those needs covered internally, and all with a
small footprint!

43. Why Quasar?
Because of the simplicity and power offered to you out of the box. Quasar, with its
CLI, is packed full of features, all built to make your developer life easier.
Next we’ll show you a list, this is a non-exhaustive list of Quasar’s great aspects
and features.

44. Why Quasar?
All Platforms in One Go
One authoritative source of code for all platforms, simultaneously: responsive
desktop/mobile websites (SPA, SSR + SPA client takeover, SSR + PWA client
takeover), PWAs (Progressive Web Apps), mobile apps (that look native) and
multi-platform desktop apps (through Electron).

45. Why Quasar?
The largest sets of Top-Class, fast and responsive web components
There’s a component for almost every web development need within Quasar.
Each of Quasar’s components is carefully crafted to offer you the best possible
experience for your users. Quasar is designed with performance &
responsiveness in mind – so the overhead of using Quasar is barely noticeable.
This attention to performance and good design is something that gives us special
pride.

46. Why Quasar?
Best Practices - Quasar was also built to encourage developers to follow web
development best practices. To do this, Quasar is packed full of great features out
of the box.
● HTML/CSS/JS minification
● Cache busting
● Tree shaking
● Sourcemapping
● Code-splitting with lazy loading
● ES6 transpiling
● Linting code
● Accessibility features
Quasar takes care of all these web develoment best practices and more - with no
configuration needed.

47. Why Quasar?
Progressively migrate your existing project
Quasar offers a UMD (Unified Module Definition) version, which means
developers can add a CSS and JS HTML tag into their existing project and they’re
ready to use it. No build step is required.

48. Why Quasar?
Unparalleled developer experience through Quasar CLI
When using Quasar’s CLI, developers benefit from:
State preserving hot module reload (HMR) - when making changes to app source code, no matter if it’s a
website, PWA, a Mobile App (directly on a phone or on an emulator) or an Electron app. Developers
simply change their code, save the changes and then watch it get updated on the fly, without the need of
any page refresh.
State preserving compilation error overlay
Lint-on-save with ESLint – if developers like linting their code
ES6 code transpiling
Sourcemaps
Changing build options doesn’t require a manual reload of the dev server
And many more leading-edge developer tools and techniques

49. Why Quasar?
Get up to speed fast
The top-class project intitialization feature of the CLI makes getting started very
easy for you, as a developer. You can get your idea to reality in record time. In
other words, Quasar does the heavy lifting for you, so you are free to focus on
your features and not on boilerplate.

50. Why Quasar?
Awesome ever-growing community
When developers encounter a problem they can’t solve, they can visit the Quasar
forum or our Discord chat server. The community is there to help you. You can
also get updates on new versions and features by following us on Twitter. You can
also get special service as a Patreon and help make sure Quasar stays relevant
for you in the future too!

51. Why Quasar?
A wide range of platform support
Google Chrome, Firefox, IE11/Edge, Safari, Opera, iOS, Android, Windows
Phone, Blackberry, MacOS, Linux, Windows.
Quasar Language Packs
Quasar comes equipped with over 40 language packs out of the box. On top of
that, if your language pack is missing, it takes just 5 minutes to add it.

52. Why Quasar?
Great documentation
And finally, it’s worth mentioning the significant amount of time taken to write
great, bloat-free, focused and complete documentation, so that developers can
quickly pick up Quasar. We put special effort into our documentation to be sure
there is no confusion.
Get started in under a minute
Having said this, let’s get started! You’ll be running a website or app in under a
minute.

53. Underlying technologies
Vue, Babel, Webpack, Cordova, Electron.
Except for Vue, which takes half a day to pick up and will
change you forever, there is no requirement for you to know
the other technologies. They are all integrated and configured
in Quasar for you.
