Editor's Notes
- Good morning everyone. I’m very glad to be here today. My name is Kazuhito Yokoi from Hitachi and I am one of contributors to Node-RED. Today, I would like to talk about Hitachi’s contributions to Node-RED project.
- First of all, I will explain why Hitachi contributes to Node-RED. We are using Node-RED in our IoT platform, “Lumada”. To add new features and improve quality of code, we joined the Node-RED community as a contributor. As you can see on JS Foundation blog, there is the announcement about it.
- Next, let me talk about how much Hitachi has contributed to the Node-RED project. We started our contributions last year. In just a year, we were able to add over one hundred commits and sixteen thousand lines of code. On the GitHub page, there are five contributors from Hitachi.
- From this slide, I will explain about Hitachi’s current and future contributions to the Node-RED project. The following are current contributions. The first is project feature. The new functionality in version zero point eighteen is to manage flows using version control. Nick developed the functionality with the help of Mr. Nakamura. The second is message sequence nodes. As shown on the palette in version zero point eighteen, you can use sort and batch nodes. To handle sequence of messages, Dr. Nishiyama added these nodes.
- Third is customizing a node’s icon. In version zero point eighteen, users can customize the node’s icons according to their needs. Mr. Nakanishi developed the function. Forth is internationalization of flow editor. If you change your browser language to Japanese, you can see Japanese messages on the flow editor. Currently Chinese language is also supported on the flow editor. Mr. Xiu and I translated English messages into Japanese and Chinese with the assistance of other contributors in Node-RED community. With this function, I hope that Japanese and Chinese users will increase.
- This slide shows the future contributions from Hitachi. The first is context backend plugin. To keep data when Node-RED instance restarts, Mr. Uchikawa is developing the function. The second is node generator. Using the tool, users can easily create original nodes from Swagger definition and JavaScript code in function node. Mr. Ide and I are developing a command line tool with other contributors. If you are interested in the tool, please refer to the URL, node-red-nodegen under the Node-RED project.
- And we published five thousand copies of Node-RED book in Japan. Today, I brought ten copies of Node-RED book as giveaways. Please approach me after my presentation if you want to get it.
- Finally I’d like to introduce how to join the Node-RED community. For discussion, there are the Slack and Google Groups in community. If you want to get updates about Node-RED, you can join the community through Node-RED website. Thank you for your listening. Have a nice day.
