I am using Express for web services and I need the responses to be encoded in utf-8.
I know I can do the following to each response:
response.setHeader('charset', 'utf-8');
Is there a clean way to set a header or a charset for all responses sent by the express application?
setHeader(name, value) (Added in v0. 4.0) method is an inbuilt application programming interface of the 'http' module which sets a single header value for implicit headers. If this header already exists in the to-be-sent headers, its value will be replaced.
Express. js use different kinds of middleware functions in order to complete the different requests made by the client for e.g. client can make get, put, post, and delete requests these requests can easily handle by these middleware functions.
Just use a middleware statement that executes for all routes:
// a middleware with no mount path; gets executed for every request to the app app.use(function(req, res, next) { res.setHeader('charset', 'utf-8') next(); });
And, make sure this is registered before any routes that you want it to apply to:
app.use(...); app.get('/index.html', ...);
