The Node.js agent now has limited support for running on Macs with the M1/M2 chip. One limitation is the Node.js agent does not yet support running Alpine based docker containers on the Apple M1/M2 (ARM64). Running Slim based Docker images is supported.
The agent has network connectivity with the Contrast server.
Using the Node.js agent requires increasing the application's available CPU and memory due to the increased processing and analysis of inbound information. Using the Node.js agent will use more resources than your application on its own. CPU load will also increase but this is heavily influenced by the specific application architecture and existing CPU usage profile.
If you are using Assess, you should double the available memory in each container compared to what you would normally use without the Contrast Node.js agent.
The Contrast Node.js agent requires access to npm and /bin/sh to function correctly. The agent’s functionality will be degraded and may not report findings or libraries when installed in an application that runs on a distroless container image that does not include those programs/packages.
To see if Node is installed, open the Windows Command Prompt, Powershell or a similar command line tool, and type node -v . This should print the version number so you'll see something like this v0. 10.35 . Test NPM.
Keeping the Node. js version up-to-date can boost your app's performance (but doesn't necessarily have to). It also gives the developers the ability to work with modern native solutions, such as async/await and other ES6/7 features, which can make the development process faster.
It's simple. If you want to install all the node_modules from the package. json file you simply put: npm install in terminal (on the same directory where the package. json exists) and it would install all the node modules in the folder called node_modules .
Unlike the browser where Javascript is sandboxed for your safety, node. js has full access to the system like any other native application. This means you can read and write directly to/from the file system, have unrestricted access to the network, can execute software and more.
Go to task manager find processes with name of node get it's pid, get it's port number using pid and netstat command.Match the port number with your application you can verify that your application was running.
In a web browser, navigate to the Node.js Downloads page.Click the Windows Installer button to download the latest stable version with long-term support (LTS). The installer also includes the NPM package manager. The file is saved in the Downloads folder by default.
Concurrency Issues: Node. js operates on a single-threaded event loop, which can be a limitation for CPU-intensive tasks. Although it excels in handling I/O-bound tasks, heavy computation can block the event loop, impacting performance.
After you have installed node it is just javascript running on your machine, instead of running in the web browser. So yes to that extend it can be used without connection to the internet. It gives your computer the ability to interpret javascript code and execute whatever instructions you gave it.
After installing the validator module you can check your validator version in the command prompt using the command. After that, you can just create a folder and add a file for example index. js, To run this file you need to run the following command.
You'll need to open a new terminal (command prompt) for the node and npm command-line tools to be on your PATH. To test that you have Node.js installed correctly on your computer, open a new terminal and type node --version and you should see the current Node.js version installed.
