TypeAudit allows you to check the types of variables, arguments and other values where necessary.
Installation
To install the stable version:
npm install --save type-audit
This assumes you are using npm as your package manager.
Usage
Checking arguments:
import TypeAudit from 'type-audit';
...
function someFunction(id, data) {
TypeAudit.notEmptyString(id, 'arg:id', true);
TypeAudit.object(data, 'arg:data');
...
}
...
someFunction('abc', {prop:'123'}); // It's Ok
someFunction('abc', null); // It's Ok
someFunction('abc'); // It's Ok
someFunction(''); // Throws TypeError: 'Argument "id" must be not empty string'
someFunction(); // Throws TypeError: 'Argument "id" must be not empty string: undefined'
someFunction(123); // Throws TypeError: 'Argument "id" must be not empty string: 123'
someFunction('abc', '123'); // Throws TypeError: 'Argument "data" can be only an object: 123'
Checking various values:
import TypeAudit from 'type-audit';
...
function someFunction(data) {
...
TypeAudit.positiveInteger(data.level, 'threshold:level');
TypeAudit.notNegativeNumber(data.num, 'value:num', true);
...
}
...
someFunction({level:17, num:0}); // It's Ok
someFunction({level:null, num:1}); // It's Ok
someFunction({num:3}); // It's Ok
someFunction({level:0, num:7}); // Throws TypeError: 'Threshold "level" can be only positive integer: 0'
someFunction({num:'abc'}); // Throws TypeError: 'Value "num" must be not negative number: abc'
Checking values in react components:
import TypeAudit from 'type-audit';
...
class MyComponent extends React.Component {
static propTypes = {
...
someProp: TypeAudit.prop.integer.isRequired;
...
}
...
}
Checking values in conditions:
import TypeAudit from 'type-audit';
...
if (TypeAudit.is.notEmptyArray(value, true) && TypeAudit.is.arrayOf(value, SomeClass, true)) {
// value is ok
}
else {
// bad value
}
...
