FHIR json schema validator
npm install @asymmetrik/fhir-json-schema-validator> Utility for validating FHIR resources
``shell`
yarn add @asymmetrik/fhir-json-schema-validator
@asymmetrik/fhir-json-schema-validator exports a single class called JSONSchemaValidator. This class takes two optional
arguments for initialization:
> #### schema
>
> This is the path to the JSON schema that you would like to validate against. It defaults to the file
> included in this package.
#### ajvSettings
This is an object with the settings to pass on to AJV. It defaults to suppresses log and warn messages, but logs error
messages. For a full list of AJV options see the README on the AJV GitHub page athttps://github.com/epoberezkin/ajv.
`
// Default initialization:
let defaultValidator = new JSONSchemaValidator();
// Custom initialization
let defaultValidator = new JSONSchemaValidator(schema, ajvSettings);
`
The QueryBuilder class has a method called validate which takes two arguments:
> #### resource
>
> The resource that is to be validated against the FHIR JSON schema.
> #### verbose
>
> Boolean value specifying whether or not to return the full set of validation errors (true) or to take the time to
> condense error messages (false). Defaults to false. The error messages generated by the over-arching json schema
> are too numerous to be of any use. For any specific resource, we can compile a resource-specific validator and
> re-validate to get more concise and helpful error messages.
The validate method returns an array that contains any errors generated from validation.
This list will be of length 0 if no errors were found.
