Safe Await
Safely use async/await without all the try catch blocks
[error, data]promise signatures- Throws on native errors
Usage
const safeAwait = require('safe-await')
async function fooBar() {
const [error, data] = await safeAwait(promiseOne())
if (error) {
// handle error, retry, ignore, whatever
}
console.log(data)
}See usage and tests for more examples.
