enjoi
Converts a JSON schema to a Joi schema for object validation.
Schema Support
enjoi is built against json-schema v4, but does not support all of json-schema (yet).
Here is a list of some missing keyword support still being worked on:
notformatobject:patternPropertiesarray:items(supports as single schema, not supported as array of schemas).array:additionalItems
API
enjoi(schema [, options])schema- a JSON schema or a string type representation (such as'integer').options- an (optional) object of additional options such assubSchemasand customtypes.subSchemas- an (optional) object with keys representing schema ids, and values representing schemas.types- an (optional) object with keys representing type names and values representing a Joi schema.
Example:
var Joi = require('joi');
var Enjoi = require('enjoi');
var schema = Enjoi({
'title': 'Example Schema',
'type': 'object',
'properties': {
'firstName': {
'type': 'string'
},
'lastName': {
'type': 'string'
},
'age': {
'description': 'Age in years',
'type': 'integer',
'minimum': 0
}
},
'required': ['firstName', 'lastName']
});
Joi.validate({firstName: 'John', lastName: 'Doe', age: 45}, schema, function (error, value) {
error && console.log(error);
});Can also call validate directly on the created schema.
schema.validate({firstName: 'John', lastName: 'Doe', age: 45}, function (error, value) {
error && console.log(error);
});Sub Schemas
Example:
var schema = Enjoi({
'title': 'Example Schema',
'type': 'object',
'properties': {
'A': {
'$ref': 'sub#/something'
}
}
}, {
subSchemas: {
'sub': {
'something': {
'type': 'string'
}
}
}
});Custom Types
var schema = Enjoi({
type: 'file'
}, {
types: {
file: Enjoi({
type: 'object',
properties: {
file: {
type: 'string'
},
consumes: {
type: 'string',
pattern: /multipart\/form-data/
}
}
})
}
});
schema.validate({file: 'data', consumes: 'multipart/form-data'}, function (error, value) {
error && console.log(error);
});
