Section Create a folder, such as myapp. After npm init is in it, the node_modules dependent folder will also be created. Use npm install -- save to install the following dependencies: 1. express 2. mysql 3. body-parser (used to parse the post parameter) Because express does not seem to have its own database encapsulation, it generally creates a new models folder and then writes the database logic. If you just want to perform a simple test, you can directly write it in app.

. pipe (parser ). pipe (transformer) // process the data transmitted from the previous stream. pipe (es. map (function (data, callback) {up Load (data, function (err) {callback (err) ;}) // listens to the end event of the previous stream. pipe (es. wait (function (err, body) {process. stdout. write ('done! ');})); More Methods You can refer to the https://github.com/jeresig/node-stream-playground, go to the sample site and click add stream to see the

the template mode here, the way to subclass extension is Decode method.The main logic is to put all the data into the cumulative area, the subclass from the accumulation of data extracted from the accumulated area into an array, Bytetomessagedecoder will loop array calls the following handler method, the data frame sent to the business handler. Complete the decoding logic for this.In this way, whether it is a sticky bag or unpacking, it can be perfectly implemented.There are some small details:

Introduction The popularity of JavaScript has brought about many changes, so that the form of using it for network development has become completely different. Just like in a browser, we can also run JavaScript on the server, from the frontend to the backend.

files that are being uploaded online on the website. In this way, real-time audio and video encoding can be implemented, as well as code between different data sources (see Proxy for the next paragraph).(I note: Node has to replace the webserver such as Apache processing data, so developers can directly receive the client a copy of the uploaded data, and real-time processing.
