## Installation

```
## Changes
### v2.0.0 - BREAKING
- Objects parsed as multiple arguments, should now only be passed as a JSON object in 1 argument.
**before**
```
["function","prop1","prop2"]
```
```javascript
const verifiedArgs = await Helpers.checkArgs<{ prop1: string, prop2: string }>(args, Yup.object()
.shape({
prop1: Yup.string().required(),
prop2: Yup.string().required(),
}));
```
**after**
```
["function","{\"prop1\":\"prop1\",\"prop2\":\"prop2\"}"]
```
```javascript
const verifiedArgs = await Helpers.checkArgs<{ prop1: string, prop2: string }>(args[0], Yup.object()
.shape({
prop1: Yup.string().required(),
prop2: Yup.string().required(),
}));
```
