# Safe Error

This module is inspired by how golang handles errors, and allows you catch errors in a similar manner

## Example

```javascript

  const  {safe} = require('safe-error')

  const safeJsonParse = (str) => safe( () => JSON.parse(str))

  const {result, error} = safeJsonParse('{"msg": "Hello World}')

  if(error) {

    console.log('Invalid Json')  

  }

  else {

    console.log(result)

  }

```

It can also handle promise functions

```javascript

  const axios = require('axios')

  const {safeAsync} = require('safe-error')

  const safeGET = (url) => safeAsync( () => axios.get(url))

  const main = async () => {

    const {result, error} = await safeGET('http://invalidurl')

      if(error) {

        console.log('Failed to call endpoint', error)  

      }

      else {

        console.log(result.data)

      }

  }

  main()

```

## API

`type Result = {error: Error|null, result: T|null}`

`safe( () => T) => Result`

`safeAsync( () => Promise) => Promise`
