Package Exports

express-validator
express-validator/lib/express_validator

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (express-validator) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

express-validator

An express.js middleware for node-validator.

This is basically a copy of a gist by node-validator author chriso.

Usage

var express = require('express'),
    expressValidator = require('express-validator'),
    app = express.createServer();

app.use(express.bodyParser());
app.use(expressValidator);

app.post('/:foo', function(req, res) {
  var errors = [];
  req.onValidationError(function(msg) {
    console.log('Validation error: ' + msg);
    errors.push(msg);
  });

  req.mixinParams();

  req.assert('postparam', 'Invalid postparam').isInt();
  req.assert('getparam', 'Invalid getparam').isInt();
  req.assert('foo', 'Invalid foo').isAlpha();

  req.sanitize('postparam').toBoolean();

  if (errors.length) {
    res.send('There have been validation errors: ' + errors.join(', '), 500);
    return;
  }
  res.json(req.params);
});

app.listen(8888);

Which will result in:

$ curl -d 'postparam=1' http://localhost:8888/test?getparam=1
{"foo":"test","getparam":"1","postparam":true}

$ curl -d 'postparam=1' http://localhost:8888/t1est?getparam=1
There have been validation errors: Invalid foo

$ curl -d 'postparam=1' http://localhost:8888/t1est?getparam=1ab
There have been validation errors: Invalid getparam, Invalid foo
