express-busboy
A simple body-parser
like module for express that
uses connect-busboy
under the hood.
It's designed to be more of a "drop in" replacement for body-parser
.
With it populating req.body
, there is very minimal code change needed to use it.
usage
var bb = require('express-busboy');
var app = express();
bb.extend(app);
The module will populate req.body
and req.files
like the body-parser
module does.
configuration
bb.extend(app, {
//options can go here
});
By default this module will create an Array
when it finds multiple fields with the
same name in the POST parameters. You can set restrictMultiple
to true
to
not parse mutiple POST values into Array
's
file uploads
By default file uploads are disabled, the req.files
object will always be empty. You can activate them with:
bb.extend(app, {
upload: true,
path: '/path/to/save/files',
allowedPath: /./
});
path
will default to: os.tmpdir()/express-busboy/<uuid>/<the field name>/<filename>
.
allowedPath can contain a regular expression limiting the upload function to given urls. For example /^\/upload$/
would only allow uploads in the /upload path.
You can have a function returning true/false if you prefer that:
options.allowedPath = function(url) {
return url == '/upload';
}
You can restrict uploads to specific mimetypes as well:
options.mimeTypeLimit = [
'text/x-markdown',
'application/javascript',
'image/jpeg',
'image/png'
];
When files are not uploaded due to path or mimetype checks, no error is returned (so the other data in the request can be handled) the restricted item
will simply not appear in the req.files
Object
.
