DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), ... methods instead
I have an angular project and recently I have added angular-universal to it using the following command:
ng add @nguniversal/express-engine --clientProject {{ name of your project }}
building and running it:
npm run build:ssr && npm run serve:ssr
Ive got many errors after doing so but I managed to get it to work, but when I access my home page its writing the following to the console:
(node:44714) [DEP0005] DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() methods instead.
ERROR [Error]
ERROR [Error]
and each time I refresh the page it print ERROR [Error] again without any details, please note that I don't have any new Buffer() in my code, and I have followed the suggestions on stack overflow to solve this but no luck, can someone help to figure out what's causing this?
I have solved the ERROR [Error] by removing the TranslateService, but still having the deprecationWarning
Answer
In case you're using Buffer() in your code just replace it with:
new Buffer(number) // Deprecated
Buffer.alloc(number) // New
Or
new Buffer(string) // Deprecated
Buffer.from(string) // New
In case you're not using Buffer() anywhere you have to do the following:
1) Search all of your app dependencies (You might use a tool for searching by clicking the search icon in the IDE your currently using and type Buffer())
2) Wherever you find a Buffer() in a module or dependency just replace it as mentioned above
