Validate the current property if another property is set.
E.g you have a URL property of a schema, which is not a required field. You only want to apply validation to that field if another field has a value.
npm install validity-validate-if-property-set --save
Below is a simple example for usage with schemata and save:
var validity = require("@clocklimited/validity"),
schemata = require("schemata"),
save = require("save"),
collection = save("author"),
validateIfPropertySet = require("@clocklimited/validity-validate-if-property-set");
var schema = schemata({
useLink: { type: Boolean },
url: {
type: String,
validators: { all: [validateIfPropertySet("useLink", validity.url)] },
},
});
