main still holds the reference to the initial main module then.Īlexandre Morgaut pointed out that require. mainModule to something else during runtime (I have no idea why I would do this, but yeah ¯_(ツ)_/¯) require. ( function ( exports, require, module, _filename, _dirname ) Īha! It turns out that if we set process.
#NODEJS PROCESS CODE#
We measure the code execution time by providing the time returned by the first process.hrtime () call as a parameter in the second process.hrtime () call. Let's do a quick refresher first: in Node.js every module and required file is wrapped in a so called module wrapper. The process.hrtime () method to measure code execution time which returns array which include current high-resolution real time in a seconds, nanoseconds. This is how you could do it in the browser but how does this work in Node.js? This brings to me learning of the weekend. in Frontend land // index.html // foo.js const currentScript = document. the issue of accessing module meta information like what the script current element is. In your settings file.I was reading the ta proposal for JavaScript over the weekend. Process Events The process object is an instance of EventEmitter and emits the following events Example Create a js file named main. There are several methods available in a process object.
Static file name either as a command-line argument or using the flowsFile option The process object is a global object and can be accessed from anywhere. You are running on may change its hostname, then you should ensure you provide a Node-RED uses flows_.json as the default flows file. If the Projects feature is enabled, this identifies which project should be started. If the Projects feature is not enabled, this sets the flow file you want to work with. When you deploy your changes, the flows are then started. The cluster module provides a way of creating child processes that runs simultaneously and share the same server port. This allows you to open the flows in the editor and make changes without the flows running. Use the JavaScript debug terminal, similar to using the. Starts Node-RED without starting the flows. js programs in VS Code: Use auto attach to debug processes you run in VS Codes integrated terminal. Sets the TCP port the runtime listens on. Node-RED can be started using the command node-red. This by providing the flow file name as argument to the node-red command.
