joshuawise / wise-inspection

Synchronous inspection for native promises.

wise-inspection

This package augments native promises (or a subclass thereof) with synchronous inspection capabilities.

This is only possible for Node.js versions 8 and up.

Installation

npm install --save wise-inspection

Usage

require('wise-inspection')(Promise);

const promise = Promise.resolve('foobar');
console.log(promise.inspect());
// => { state: 'fulfilled', value: 'foobar' }

The descriptor object

If the promise is:

• fulfilled, the descriptor will be { state: 'fulfilled', value: <fulfillmentValue> }
• rejected, the descriptor will be { state: 'rejected', reason: <rejectionReason> }
• pending, the descriptor will be { state: 'pending' }

wise-inspection's Issues

A different API would be better

Imho it would be better to use methods or constants instead of using state strings. e.g. let state = promise.inspect(); console.log(state.isFullfilled()); or console.log(promise.isFulfilled());. Method and constant names can be auto-completed and so harder to mistype.
