Koa applications extend an internal EventEmitter. Middleware to execute downstream, the stack will unwind and each middleware is resumed to performĬtx.er = await User.find(id) ctx.appĪpplication instance reference. The function suspends and passes control to the next middleware defined. The x-response-time and logging middleware to mark when the request started, then yields control through the response middleware. The following example responds with "Hello World", however first the request flows through

However with async functions we can achieve "true" middleware. This was previously difficult to make user friendly with node's use of callbacks. ReaderStream.Koa middleware cascade in a more traditional way as you may be used to with similar tools. Handle stream events -> data, end, and error Var readerStream = fs.createReadStream('input.txt')

To teach the world in simple and easy way!!!!!Ĭreate a js file named main.js with the following code − Tutorials Point is giving self learning content Reading from a StreamĬreate a text file named input.txt having the following content − This tutorial provides a basic understanding of the commonly used operations on Streams. For example, some of the commonly used events are −ĭata − This event is fired when there is data is available to read.Įnd − This event is fired when there is no more data to read.Įrror − This event is fired when there is any error receiving or writing data.įinish − This event is fired when all the data has been flushed to underlying system. Transform − A type of duplex stream where the output is computed based on input.Įach type of Stream is an EventEmitter instance and throws several events at different instance of times. Writable − Stream which is used for write operation.ĭuplex − Stream which can be used for both read and write operation. Readable − Stream which is used for read operation.

In Node.js, there are four types of streams − Streams are objects that let you read data from a source or write data to a destination in continuous fashion.
