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.

Readme

express-validator

An express.js middleware for node-validator.

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

Installation

npm install express-validator

Usage

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

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

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

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

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

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

app.listen(8888);

Which will result in:

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

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

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

You can extend the Validator and Filter objects to add custom validation and sanitization methods:

var expressValidator = require('express-validator');

expressValidator.Filter.prototype.toLowerCase = function(){
  this.modify(this.str.toLowerCase());
  return this.str;
};
