  • V8 Hidden class
    Masami Yonehara 2018.06.27

    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.

  • Presenting on RedisConf18
    Jongyeol Choi 2018.06.18

    As a member of the Storage team for LINE Messenger Server, I develop modules related to Redis.

    Hello, I am Jongyeol Choi, a member of the Redis team at LINE. LINE's services use various storage systems based on their needs. Our messaging service uses various open source storage systems such as Redis, HBase, and Kafka. As a member of the Redis team, I participated the RedisConf18 conference in San Francisco in U.S.A, on April 26th, as a speaker. The topic of my session was, "Redis at LINE, 25 billion messages per day". I'd like to take this opportunity to share the presentation preparation process, the conference itself and the responses I got for my session.

    What is LIFF?

    LIFF is one of our latest products out for LINE Messaging API users. So, what is LIFF? LIFF stands for the LINE Front-end Framework, a web app platform that runs inside the LINE app. LIFF apps running on the LINE app can obtain LINE user ID or tokens needed to use the LIFF API. With the information obtained, LIFF apps can provide features using user information, such as sending messages on behalf of the user.
