$ npm install validate-value
First you need to integrate validate-value into your application:
const { Value } = require('validate-value');
If you use TypeScript, use the following code instead:
import { Value } from 'validate-value';
Then, create a new instance and provide a JSON schema that you would like to use for validation:
const value = new Value({
type: 'object',
properties: {
username: { type: 'string' },
password: { type: 'string' }
},
additionalProperties: false,
required: [ 'username', 'password' ]
});
Afterwards, you may use the validate
function to validate a value:
const user = {
username: 'Jane Doe',
password: 'secret'
};
try {
value.validate(user);
} catch (ex) {
// ...
}
By default, the error message uses value
as identifier and .
as the separator for the object that is validated, but sometimes you may want to change this. Therefor, provide the desired identifier and separator as second parameter to the validate
function:
const user = {
username: 'Jane Doe',
password: 'secret'
};
try {
value.validate(user, { valueName: 'person', separator: '/' });
} catch (ex) {
// ...
}
From time to time, you may not be interested in the actual error, but only in the fact whether the given object is valid or not. For these cases, use the isValid
function:
const user = {
username: 'Jane Doe',
password: 'secret'
};
console.log(value.isValid(user));
// => true
