How to set a limit on the uploaded file (different limits for different routes)?

Question

Node.js

Sobsna, the question is in the title, I use the express-fileupload, body-parser packages.
I tried to set it like this, in general for all routes:

• app.use(bodyParser.json({limit: 2 * 1024 * 1024, extended: true}));
  
• app.use(fileUpload({limits: { fileSize: 2 * 1024 * 1024 }}));
  

Doesn't work, large files still upload.

Answer 1

body-parser does not control file uploads (multipart), so the restriction will affect only data
express-fileupload uses the busboy parser, the limits for which actually limit file recognition to the size you specified. Those. will be loaded, but will not be parsed.
To limit the loading of the POST body, use nginx as a limiter, and nodejs as a handler only.
