Simple, flexible rule engine for the amazing react-jsonschema-form
If you are familiar with react-jsonschema-form and interested in adding some dynamism to the forms, for example, hiding/disabling parts of the form, adding extra options to select, radio buttons, changing data and many more, it's worth a try.
ffmpegui - experimental project based on ruled-jsonschema-form
Example + some documentation:
/*** Defining schema*//*** Defining ui schema with form rules*** A form rule is an object containing the following properties:* - desc (string, optional): short description of the rule* - if (string): expression must be evaluated to boolean* - then (string): expression, runs when the above is true* - else (string, optional): expression, runs otherwise* - active (boolean): flags the rule as active or inactive*** The following values can be used in the scope of the expressions (if, then, else) - check the doc of react-jsonschema-form for the details* - formContext (object): "global" form property can hold anything* - schema (object): schema of the actually processed node* - uiSchema (object): ui schema of the actually processed node* - idSchema (object): id schema of the actually processed node* - data (object): form data of the actually processed node* - arrayUiSchema (object) - in case of the processed item is an array element, the array's uiSchema is offered here*//*** Setup the form as a usual react-jsonschema-form*/
