Hi, I'm Shibasaka Hiroyuki, a front-end engineer at LINE Kyoto development office. Do you listen to music on your computer while working or studying? Not only is LINE MUSIC available as a smartphone app, it's also available as a web application. The web app that we've developed, uses Vue.js as its JS framework. LINE Music (web app) Previously, this web app had used Vue 2, but in June 2022, we newly released a version upgraded to Vue 3. In parallel with function development for this web app, my

TL;DR:The baseline for web development in 2022 is: low-spec Android devices in terms of performance, Safari from two years before in terms of Web Standards, and 4G in terms of networks. The web in general is not answering those needs properly, especially in terms of performance where factors such as an over-dependence on JavaScript are hindering our sites' performance. Hello there! I'm Alan Dávalos, a front-end engineer at LINE. You might have thought this article's titl

I am a frontend engineer at LINE. I've moved from Fukuoka to Tokyo in 2016.
As a frontend engineer, I feel I still need to know more about the structure of JavaScript and web browsers, in order to provide quality UX to our users. Thankfully, we are given an access to peak through JavaScript's thoughts, thanks to Google and Mozilla for making their engine code available to public, along with nicely prepared documentation. The availability of various means for tracing and profiling code surely helps too. I'd like to take this opportunity to take you through hidden class,

Hi, I'm @sunderls from LINE MANGA team where I mostly write JavaScript. Did you know that you can read free Manga directly from LINE1)? Has anyone tried it?

Because it runs in within the LINE app, we have put in a great effort to create a smooth user experience, and as one of the means to accomplish our goal, we have chosen code-splitting. Today, I'd like to introduce
