I am trying to use exceljs package in Angular 15 project, however I got this error

Error: node_modules/exceljs/index.d.ts:2003:18 - error TS2307: Cannot find module 'stream' or its corresponding type declarations.

So, does this mean that I can not use exceljs in my Angular project? I want to use this to generate xlsx with some cell formatting. Or, do you have any alternative to exceljs?

It's a NodeJS library. It's not designed to be used in the browser, where Angular apps run, but on the server, with NodeJS.

So, it's impossible to add that in my frontend app?

Apparently it is, since it publishes a browserified version. See https://www.npmjs.com/package/exceljs#contents and search for Browserify. But I still think you'd better make your frontend simpler and let the backend deal with that.

npm

I can't get the docs to install the browser version to my angular app, by any chance, do you know how to install it to an angular project?
