superagent-jsonp

Adds jsonp behaviour to superagent.

To use with browserify

First install with npm

npm i superagent-jsonp --save

Then use like so;

1const superagent = require('superagent');
2const jsonp = require('superagent-jsonp');
3superagent.get('http://example.com/foo.json').use(jsonp).end(function(err, res){
4  // everything is as normal
5});

To use with bower

First install:

bower i superagent-jsonp --save

Include it from your bower components in the usual way

Then use pretty much as you do above

1superagent.get('http://example.com/foo.json').use(superagentJSONP).end(function(err, res){
2  // everything is as normal
3});

Available options for the jsonp function

• callbackParam: The name of the query parameter that contains the function name to call. Defaults to callback.
• callbackName: Optional. The name of the callback function
• timeout: How long to wait until this is considered to be an unsuccessful request.
  • Note: all unsuccessful requests are currently treated as 404s

Usage

1superagent
2  .get('http://example.com/obviously_404.json').use(jsonp({
3      timeout: 3000,
4      callbackName: 'someOtherName'
5    })).end((err, response) => {
6      // response => {}
7      // err => new Error('404 NotFound')
8    });
