    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.

    Yasunori Iwatsuki 2018.04.03

    LINE Japan's office relocated in April, 2017 to JR Shinjuku Miraina Tower to accommodate its growing number of staff. At the time of relocation, the IT support department introduced a number of new systems into the company. One of those is the LINE Floor Map system which I am going to share with you in this post.

    Background story

    Before we moved to Shinjuku, we used to manage our floor map with Microsoft Excel. Here is a part of the excel file. (We've erased names off from the screenshot.)

  • Easy code-splitting with grow-loader
    sunderls 2018.01.24

    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? As we shared on our previous post, LINE MANGA: Smooth page transition with Page Stack, LINE MANGA is built with web technologies. 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 the grow-loader, LINE's open source project for code-splitting.
