{"library":"node-fingerprint","title":"Node.js Process Fingerprinter","description":"The `node-fingerprint` package provides a straightforward utility for generating a unique identifier for a Node.js process instance. It computes this fingerprint by hashing a combination of the process ID (`pid`) and the hostname of the machine it's running on. This design is explicitly inspired by concepts found in `cuid` for generating short, unique IDs. The current stable version is 1.1.0, which was last published over a decade ago in August 2015, indicating that the project is no longer actively maintained. Its primary use case is for simple, local process identification within a single machine's context, rather than for global or persistent unique identifiers, or browser-based fingerprinting offered by other, more complex solutions like FingerprintJS. It distinguishes itself by its extreme simplicity and minimal dependencies, focusing solely on the OS-level process and host information.","language":"javascript","status":"abandoned","last_verified":"Sun Apr 19","install":{"commands":["npm install node-fingerprint"],"cli":null},"imports":["const generateFingerprint = require('node-fingerprint');\nconst fingerprint = generateFingerprint();","const generate = require('node-fingerprint');\nconst myProcessFingerprint = generate();"],"auth":{"required":false,"env_vars":[]},"quickstart":{"code":"const generateFingerprint = require('node-fingerprint');\n\n// Get the current process's fingerprint\nconst fingerprint = generateFingerprint();\n\nconsole.log(`Node.js Process Fingerprint: ${fingerprint}`);\nconsole.log('This fingerprint is derived from the process ID (pid) and hostname.');\nconsole.log('It will change if the process restarts or runs on a different machine.');\n\n// Example of how it would be different if run multiple times (simulated)\nconst anotherFingerprint = generateFingerprint();\nconsole.log(`Another (simulated) fingerprint call: ${anotherFingerprint}`);","lang":"javascript","description":"Demonstrates how to import and immediately use the `node-fingerprint` package to get a process identifier.","tag":null,"tag_description":null,"last_tested":null,"results":[]},"compatibility":null}
