  - I'm working on the breaking updates of the Reader interface. This is one of the necessary features for v1.0. It compiles and passes the tests, but it has a little anomaly in deno types output. I'm still trying to solve it.

Our robot SQ2 was displayed in G20 summit in Osaka. I didn't go to the venue, but many pictures appeared which showed SQ2 there. I liked the one which showed SQ2, our manager Sungjae Kim, and Taro Kono the Minister of Foreign Affairs.

ReactJS Tokyo is a meetup of react users in Tokyo.

React users gathered in Mercari's office in Roppongi on Wednesday and listened to the talks about React. My ex-colleague @taneba presented his experience about react-testing-library. I liked his technique to create the report of the test specs and share it to non-engineers. That process seemed promising.

🐢 Tokyo Node Gakuen is a Japanese local conference of Node.js users.

We had 34th Tokyo Node Gakuen in Gran Tokyo South Tower on Thursday. This time was a special conference for the reports from JSConf EU 2019. @yosuke-furukawa talked about the package managers. We had 3 major updates from package managers: Tink, Yarn v2, and Entropic. Tink and yarn seemed heading for the similar directions, but entropic seemed having a very different goal. They all proposes very different way of managing node.js programs. I can't say which is better, but anyway they all try to change the node ecosystem significantly. @dorayakikun talked about the Workers, which is the service for edge computing by CloudFlare. @leko talked about the history of Web API adoptions in node.js. @akito0107 presented his own tool marron-glace, which is a very typescript-friendly option parser. Talks were fantastic and the party was nice as well.

🦕🇯🇵 #deno_ja is a Japanese local meetup of Deno enthusiasts.

This time we gathered at the office of LoiLo Inc. We talked about the recent changes of Deno and each person worked on their own issues. @hashrock worked on his delectron, a tool like electron, but written in Deno. @locol23 created the bundle script by deno bundle and successfuly rendered the DOM using react, crazy work. In the meeting, we decided to join the TechBookFest 7 (22th Sep, 2019), and registered to it. I brought there the stickers I created the last week and they were so popular.

Now we have 3 kinds of deno stickers. #deno_ja #denoland pic.twitter.com/EFGVKevF6S
