Advanced Rule-Based Data Validator for NodeJS.
npm install @ibrokhim/rbdvAdvanced Rule-Based Data Validator for NodeJS. https://iiiniii.github.io/RBDV-NodeJS
Let's say you are receiving a JavaScript object in your application and for using the data without a problem you have to use something like if(data != null) or if(data != undefined) each time you want to access the data's value. I know it is so annoying. Well not anymore. Using this package you can now easily create rules for the data you receive and validate it. It is like a dream, I know but, not anymore.
- [NEW] Create rule out of an example object
- Verbose validation results
- Great, advanced, easy to use and flexible configuration
- Useful in any project
- Many useful functions
- Supported data types: String, Number, Array, Function, Object, Null, Undefined, Boolean, RegExp, Error, Date, Symbol
- User-friendly feedbacks
- In case of invalid data user-friendly report
This is a Node.js module available through the npm registry.
Before installing, download and install Node.js.
Installation is done using the npm install command:
``bash`
npm install --save @ibrokhim/rbdvor
npm i --save @ibrokhim/rbdv
Check examples below on how to use this package in your project.
Install package using command below:
`bash`
npm install --save @ibrokhim/rbdv
Add the following line to the top of your JavaScript file:
`javascript`
const RBDV = require('@ibrokhim/rbdv');
Create an instance of RBDV:
`javascript`
var rbdv = new RBDV();
Set your rules for validation:
`javascript`
rbdv.setRules(rules);
If you want verbose results, then:
`javascript`
rbdv.setVerbose(true); // dafault: false
And now it is time to validate our data:
`javascript`
rbdv.isValid(data, subRuleName); // Returns true if data is valid
If you prefer single-use validation, you can do something like this:
`javascript`
rbdv.validate(data, rule); // Returns true if data is valid
You can also create a rule out of an example object:
`javascript`
rbdv.makeRule({
'name': 'Tom',
'surname': 'Jerry',
'isActive': true
});
Returns:
`bash`
{
type: 'object',
props: {
name: { type: 'string' },
surname: { type: 'string' },
isActive: { type: 'boolean' }
}
}
You can get an example configuration object in JSON format by running command below:
`javascript`
rbdv.exampleRule();
Returns:
`javascript
{
// A basic object configuration
'chat_data': {
type: 'object',
props: {
to: {type: 'string'},
from: {type: 'string'},
msg: {type: 'string'}
}
},
// A basic string configuration
'username': {
type: 'string'
},
// A basic number configuration
'age': {
type: 'number'
},
// A little bit more complex configuration
'user_data_complex': {
type: 'object',
props: {
name: {type: 'string'},
surname: {type: 'string'},
isActive: {type: 'boolean'},
contact_info: {
type: 'object',
props: {
email: {type: 'string'},
phone: {type: 'string'}
}
}
}
}
}
`
Example using a simple configuration:
`javascript
var RBDV = require("@ibrokhim/rbdv");
var rules = {
// A basic string configuration
'username': {
type: 'string'
},
// A basic number configuration
'id': {
type: 'number'
},
};
var rbdv = new RBDV(rules, true); // RBDV(rules, is_verbose)
console.log('Test #1:');
var data = "admin";
console.log(rbdv.isValid(data, 'username'));
console.log('\nTest #2:');
data = 123;
console.log(rbdv.isValid(data, 'id'));
console.log('\nTest #3:');
data = 321;
console.log(rbdv.isValid(data, 'username'));
console.log('\nTest #4:');
data = "asdf";
console.log(rbdv.isValid(data, 'id'));
`
Output:
`
Test #1:
true
Test #2:
true
Test #3:
-----------Validator Error-----------
Object Path: data
Expected: string
Got: number
Value: 321
-------------------------------------
false
Test #4:
-----------Validator Error-----------
Object Path: data
Expected: number
Got: string
Value: asdf
-------------------------------------
false
`
Example using much more complex configuration:
`javascript
var RBDV = require("@ibrokhim/rbdv");
var rules = {
'user_detail': {
type: 'object',
props: {
name: {type: 'string'},
surname: {type: 'string'},
isActive: {type: 'boolean'},
contact_info: {
type: 'object',
props: {
email: {type: 'string'},
phone: {type: 'string'}
}
}
}
}
};
var rbdv = new RBDV(rules, true); // RBDV(rules, is_verbose)
console.log('Test #1:');
var data = {
'name': 'Tom',
'surname': 'Jerry'
};
console.log(rbdv.isValid(data, 'user_detail'));
console.log('\nTest #2:');
data = {
'name': 'Tom',
'surname': 'Jerry',
'isActive': true,
contact_info: 'tom.jerry@example.com'
};
console.log(rbdv.isValid(data, 'user_detail'));
console.log('\nTest #3:');
data = {
'name': 'Tom',
'surname': 'Jerry',
'isActive': true,
contact_info: {
'email': 'tom.jerry@example.com'
}
};
console.log(rbdv.isValid(data, 'user_detail'));
console.log('\nTest #4:');
data = {
'name': 'Tom',
'surname': 'Jerry',
'isActive': true,
contact_info: {
'email': 'tom.jerry@example.com',
'phone': '5556667777'
}
};
console.log(rbdv.isValid(data, 'user_detail'));
`
Output:
`
Test #1:
-----------Validator Error-----------
Object Path: data.isActive
Expected: boolean
Got: undefined
Value: undefined
-------------------------------------
-----------Validator Error-----------
Object Path: data.contact_info
Expected: object
Got: undefined
Value: undefined
-------------------------------------
false
Test #2:
-----------Validator Error-----------
Object Path: data.contact_info
Expected: object
Got: string
Value: tom.jerry@example.com
-------------------------------------
false
Test #3:
-----------Validator Error-----------
Object Path: data.contact_info.phone
Expected: string
Got: undefined
Value: undefined
-------------------------------------
false
Test #4:
true
`
Example using single-use configuration:
`javascript
var RBDV = require("@ibrokhim/rbdv");
var rbdv = new RBDV();
var singleUseRule = {
type: 'object',
props: {
name: {type: 'string'},
surname: {type: 'string'},
isActive: {type: 'boolean'},
contact_info: {
type: 'object',
props: {
email: {type: 'string'},
phone: {type: 'string'}
}
}
}
};
var data = {
'name': 'Tom',
'surname': 'Jerry',
'isActive': true,
contact_info: {
'email': 'tom.jerry@example.com',
'phone': '5556667777'
}
};
rbdv.setVerbose(true);
console.log(rbdv.validate(data, singleUseRule));
`
Output:
`
true
