schematron¶

Yet another boilerplate-free schema validation library, Connect/Express middleware included

To get started, install schematron package via npm:

% npm install schematron

After that you will be able to use schematron library in your code. The basic usage example is as follows:

var schematron = require('schematron'),
    validate = schematron.validate,
    optional = schematron.optional,
    either = schematron.either,
    any = schematron.any;


var schema = {
  a: Number,
  b: optional(String),
  c: [either(String, Boolean)]
  d: {
    e: any,
    f: optional(Number)
  }
};

result = validate(schema, {a: 1});
if (result.errors) {
  // handle errors
} else {
  var data = result.data;
}
