Validator JS

Barebones schema validation library for things such as database schemas, api data schemas, etc.

Extensions

• Requirement (built-in)
• Type - uses Object.prototype.toString.call so make sure you use String, Number, Boolean... etc.
• Length - By itself it must be this long, otherwise as an object supports the following:
  • Min
  • Max
• Test (Regular expression tests)
  • Supports an array of RegExps as well.

Creating an extension

Implementing a feature into Validator is easy, you set the field and a callback, the callback gives you three items of data details (the whole schema, and your field is included so you can do cross checks if needed), key (the name of the parameter), data (retrieved parameter data from external source, you check against this).

Validator.implement("field", function (details, key, data) {
  this.error(key, "error-field", "No check has been done against this key!");
});

After your implementation has been ran, the validator will check for errors, if found it will exit out and return the errors. You can pass along multiple errors per run, for an example check the test implementation.

Todo

• Make extensibility easier.
• Make implementations use an object as an argument rather than multiple arguments to allow for further expansion.
• Move over to github repository.
