My first post

I will write something about the programming what I learn or try in English.

Because I have learned TypeScript, Angular, etc, I will  write about them first.

All of the posts are just for myself. But I hope they also will be useful for someone :)


If you want, you can write  some comments in English, Japanese, or Chinese.

[Angular][ASP.NET Core] Upload chunked files

Intro I wanted to send files to Web application (made by ASP.NET Core). If the file size had been small, I didn't need do any special things. But when I tried to send a large file, the error was occurred by ASP.NET Core's limitation. Though I could change the settings, but I didn't want to do that, because I hadn't known the file sizes what would been actually using. So I splitted the data into chunks first, and sent them. After receiving all chunks, I merged them into one file. There might be some libraries or APIs (ex. Stream API) what did them automatically, but I couldn't find them. What I did [ASP.NET Core] Make CORS enabled [Angular] Split a large file into chunks [Angular][ASP.NET Core] Send and receive data as form data [ASP.NET Core] Merge chunks into one file [ASP.NET Core] Make CORS enabled Because the client side application(Angular) and the server side application(ASP.NET Core) had been separated, I had to make CORS(Cross-Origin Requests)

[Nest.js] Use WebSocket with ws

Intro Until last time , I had used node-web-rtc to try WebRTC. But because the example was a little complicated for I understood the core functions of using WebRTC.

I couldn't find examples. So I don't choose at least this time. What shall I choose? According MDN, WebRTC doesn't specify strictly what technology is used on server application for connecting two devices. Signaling and video calling - Web APIs | MDN But in many examples include MDN's one use WebSocket. samples-server/s/webrtc-from-chat at master · mdn/samples-server · GitHub So I try WebSocket in the Nest.js project. Use WebSocket in a Nest.js project Nest.js has a function for using We
