Usage
const { compile } = require("@node-rs/jsonschema");
const schema = {
type: 'object',
properties: {
foo: { type: 'integer' },
bar: { type: 'string' },
},
required: ['foo'],
additionalProperties: false,
};
const input = JSON.stringify({
foo: 1,
bar: 'abc',
})
const exceptionInput = JSON.stringify({
foo: 'abc',
bar: 1,
})
const validator = compile(schema);
// check whether the input meet schema
const result = validator(input);
console.log(result); // true
const result = validator(exceptionInput);
console.log(result); // falseAPI
export declare class JSONSchema {
isValid(input: any): boolean
}
export const compile: (schema: any) => (input: string) => boolean
