node/express Force browser to download file with custom name

Question

I\'ve built a node/express website for my university project that, after searching for an ID of a law, it shows a big table with all files in different formats and languages

Answer 1

In Express 4 and later, there are 2 helper functions to change the content-type and specify attachment disposition:

res.type("application/octet-stream");
res.attachment("filename.ext");

See docs for type and attachment.
