Node.js Compatibility

Napa.js doesn't support full compatibility with node.js and necessary core modules will be added incrementally. Here are the list of what Napa.js currently supports. Please refer to https://nodejs.org/api/all.html for details.

Assert

Since Napa doesn't support Buffer yet, assert is not working on Buffer.

  • assert(value[, message])
  • assert.deepEqual(actual, expected[, message])
  • assert.doesNotThrow(block[, error][, message])
  • assert.equal(actual, expected[, message])
  • assert.fail(actual, expected, message, operator)
  • assert.ifError(value)
  • assert.notDeepEqual(actual, expected[, message])
  • assert.notEqual(actual, expected[, message])
  • assert.notStrictEqual(actual, expected[, message])
  • assert.ok(value[, message])
  • assert.strictEqual(actual, expected[, message])
  • assert.throws(block[, error][, message])

Console

  • console.log([data][, ...args])

Events

  • Event: 'newListener'
  • Event: 'removeListener'
  • EventEmitter.listenerCount(emitter, eventName)
  • EventEmitter.defaultMaxListeners
  • emitter.addListener(eventName, listener)
  • emitter.emit(eventName[, ...args])
  • emitter.eventNames()
  • emitter.getMaxListeners()
  • emitter.listenerCount(eventName)
  • emitter.listeners(eventName)
  • emitter.on(eventName, listener)
  • emitter.once(eventName, listener)
  • emitter.prependListener(eventName, listener)
  • emitter.prependOnceListener(eventName, listener)
  • emitter.removeAllListeners([eventName])
  • emitter.removeListener(eventName, listener)
  • emitter.setMaxListeners(n)
