v_rifier

Data V[a]rifier => v_rifier 😁

📚 How to use

const v_rifier = require('v_rifier');
let myVerifier = v_rifier();

or use import

🚀 Advanced Usage

1. Register Custom Type

    await myVerifier.register("myType", (value) =>  value > 100 );

So now you can use myVerifier.**isMyType**(val) to check if value is greater than 100.

    await myVerifier.isMyType(200) //> true

Or you can use myVerifier("**myType**", val) to check if value is greater than 100.

    await myVerifier('myType', 200) //> true

2. Unregister Custom Type

await myVerifier.unregister("myType");

3. Disable Loading of the Built-in Verification Functions

let myEmptyVerifier = await v_rifier({ builtIns: false });

4. Only Custom Types

After loading module, you can create your custom validation type without even loading built-ins. This provides the ability to create and use only your own custom types.

const v_rifier = require('..');

(async () => {
  let sampleVerifier = await v_rifier({ builtIns: false });

  console.log(await sampleVerifier.listTypes()); //> []

  // Create a custom type
  console.log(await sampleVerifier.register('customType', async (value) => (!isNaN(value) && value > 0))); //> true

  console.log(await sampleVerifier.listTypes()); //> [ 'customtype' ]

  // Use it

  // One way...
  console.log(await sampleVerifier('customType', 123)); //> true
  console.log(await sampleVerifier('customType', -123)); //> false

  // Or other way...
  console.log(await sampleVerifier.isCustomType(123)); //> true
  console.log(await sampleVerifier.isCustomType(-123)); //> false

  // Or Unregister It (if you want)
  console.log(await sampleVerifier.unregister('customType')); //> true

  console.log(await sampleVerifier.listTypes()); //> []

})();

5. Or a combination of built-ins and custom types

Main usecase basically, where you would want to check on something like a value being a number and also greather than some other value...while not caring about it being empty/undefined/anything else.

const v_rifier = require('..');

(async () => {
  let demoVerifier = await v_rifier();

  // Create a custom type
  console.log(await demoVerifier.register('customType', async (value) => (await demoVerifier('number', value) && value > 0))); //> true

  // Or other way...
  console.log(await demoVerifier.isCustomType(123)); //> true
  console.log(await demoVerifier.isCustomType(-123)); //> false

  console.log(await demoVerifier.isCustomType("-123")); //> false

})();
