Parsing .EML using workers

[reef merlin]

i have tried using a variety of mail parsers with workers but since workers does not have full nodejs compatibility, i am unable to use buffer or stream etc which is used by popular libs such as mailparser. is there a workaround or a compatible lib which could do it on workers?

Buffer and Stream should both be supported: https://developers.cloudflare.com/workers/runtime-apis/nodejs/#supported-nodejs-apis

Did you enable nodejs-compat flag in wrangler config?

[reef merlin]

yes.

compatibility_flags = [ "nodejs_compat" ]

wrangler.toml

i can use mailparser and buffer-dependent libs just fine, do you have a full example?
