问题 I've been following this tutorial on how to deploy a NodeJS app to Azure: https://www.youtube.com/watch?v=RWdxkhajCg0&fbclid=IwAR10Q6x8PbqLDAZZzzMX9Nvp_jEGiN_Ts4V8XLJbzF6xreq6_MB_vsbIqx8 Firstly, I did everything exactly the same way as the author showed and it all worked.

问题 this.state.videoBlob is a blob object. I used URL.createObjectURL to generate a blob URL, and passed it to fs.createReadStream, like below: fs.createReadStream(URL.createObjectURL(this.state.videoBlob)) This blob url looks like: blobURL: blob:http://localhost:3000/dabe5cdd-00cc-408a-9f3d-b0ba5f2b10b3 But I got an error saying: TypeError: fs.createReadStream is not a function The problem won't exist if I passed some online video URL. So how can I read blob from fs.createReadStream ? Thanks!
