Alternatives

Beside this module a lot of others exist which do mainly the same. With these pages I will give an overview and comparison against them.

1. JSON Schema based

JSON Schema allows to annotate and validate JSON documents. The schema itself is build using JSON like the Alinex Validator did before.

• Ajv is known as a very fast implementation of a JSON Schema based validation
• JSV is an extendable JSON Schema compliant implementation.
• z-schema is another implementation

2. String based Schema

validatorjs is defined by a single string definition per element

3. Method based

Joi comes from the Hapi server component see more on the next pages

4. Object based

Validate.js uses a constraint setting as JavaScript Object including injected reporting functions.

5. Function based

Object Schema simply validates data objects with a schema including:

• a help message
• a user defined validator function
• a user defined transformer function

6. Simple Validators

Typed basically checks against specific types but has also some settings to define value ranges...

Valida a collection of a few validation methods.

Aproba

Valido

Validotron

7. Comparison Top 3

Here a basic comparison of alinex-validator against others is shown. You may also find more detailed comparisons under each alternative's description (sub page). The values gives a hint, how complete in percent the impleentation is.

The percentage values are an assumption how far the support of some type in comparison to the complete possibilities in any of them goes.
