express - API return data in CSV format -

i'm creating api should return data in csv format. set content-type header text/csv forces download of contents csv file.

i'm using nodejs , express framework. standard behaviour. know how guys solved issue.

this sample of code i'm using:

res.set('content-type', 'text/csv'); var tocsv = require('to-csv'); // obj standard javascript object. res.send(tocsv(obj)); 

i person using api can retrieve data in csv format without downloading file

maybe have @ question: how browser determine whether download or show

it's browser decides content of type "text/csv" should downloaded.

you should consider using content-type, if want csv show in browser plain text.

try instead:

res.set('content-type', 'text/plain');
