From JQuery to Vue.js – Not Rocket Science

Time & Date

9:00, 10 June


Crowne Plaza Vilnius –
M. K. Čiurlionio str. 84, Vilnius, Lithuania



Changing applications from one technology to another can turn out to be rather very challenging depending on the type of tech stack. If you’ve ever migrated a large project then you can only imagine how daunting it could be, most especially moving from DOM manipulation stack to a Virtual DOM stack.

After becoming a Front End Engineering Team lead at BCaster I introduced an incremental migration shift from JQuery to VueJs. It sure did seem to be straightforward at first especially with proper test coverage, however 20% -25% into this migration we encountered a certain issues which meant re-evaluation of several architectural decisions that had been made in this regard.

  • Part 1: Introduction to Vue:

o    Adding Vue to your Legacy Code

o    Vue reactivity and Life Cycle

o    Migrating Legacy code one page at a time

  • Part 2: Moving to Vue Tools:

o    Moving To Vue CLI

o    Single File Components

o    NUXT for Server Side Rendering

  • Part 3: Using third party libraries:

o    Integrating third party libraries into the project

o    Setting up Global vs Page Specific libraries

o    Bonus – Using Tailwind with Vue/NUXT


 The goal of this workshop is to give a hands on step by step guide and approach for migrating legacy JS or JQuery application into a Vue JS app without needing to use the Vue CLI i.e simply using Node/Espress/Handlebars.

Target audience

The workshop is suitable for both beginners and intermediates alike. JavaScript enthusiasts who are excited about learning Vue and would prefer a step by step introduction to Vue JS will find this useful.
