Node path __dirname

Get the directories from a file path: var path = require ('path'); var directories = path.dirname('/Users/Refsnes/demo_path.js'); console.log(directories); Run example » The path.dirname() method is used to get the directory name of the given path. It ignores the respective platform's trailing directory separators. Syntax: path.dirname( path ) Parameters: This function accepts one parameter as mentioned above and described below: path: It is the file path that would be used to extract the directory name. It. Node.js __dirname Variable. Last Updated : 08 Apr, 2021. The __dirname string gives the directory path of the current module, this is also similar to that of path.dirname () of the filename. Return Value : It returns the directory path of the current module. Example 1: Let's create a file main.js The __dirname version is the most robust since __dirname will always be the directory containing the currently executing.js file, which is a better anchor than my_folder or ./my_folder which are both relative paths and will fail if the process's current working directory (process.cwd ()) is something unexpected, which is entirely possible

The __dirname variable (double underscores at the start) is a part of core Node.js since the beginning. It returns the absolute path of the directory in which the currently executing JavaScript file exists import path from 'path'; import { fileURLToPath } from 'url'; const __filename = fileURLToPath (import.meta.url); const __dirname = path.dirname (__filename); 1st get the __filename and then __dirname. both these CommonJs variables are not in ES modules, as per Node.org. we have to replicate with import.meta.url

The __dirname in a node script returns the path of the folder where the current JavaScript file resides. __filename and __dirname are used to get the filename and directory name of the currently executing file. The ./ gives the current working directory. It works similar to process.cwd () method The directory name of the current module. This is the same as the path.dirname () of the __filename. Example: running node example.js from /Users/mjr. console.log (__dirname); // Prints: /Users/mjr console.log (path.dirname (__filename)); // Prints: /Users/mjr The output of the __dirname keyword differs from sections A and B because the directory that we call it from is different. Now we are in the /tools/subTools folder, so the output includes /tools/subTools in the directory name. Summary. In this article, we learned about the difference between process.cwd() and __dirname in node.js. Both methods are useful. But depending on the situation, one may be more appropriate than the other at times 在当前目录下也就是nodejs目录运行 node path.js // 当前目录下 path.dirname(__filename) + '/path.js'; // 相邻目录下 path.resolve(__dirname, '../regx/regx.js'); 最后看看改过之后的结果,不会报错找不到文件了,不管在哪里执行这个脚本文件,都不会出错了,防止以后踩坑。 QQ20170510-193604. 推荐阅读 更多精彩内容.

If you view your live app, you should see a big HTML heading (and a form that we will use later), with no style applied. Note: You. In Node.js, __dirname is always the directory in which the currently executing script resides . So if you typed __dirname into /d1/d2/myscript.js, the value would be /d1/d2. By contrast, . gives you the directory from which you ran the node command in your terminal window (i.e. your working directory) when you use libraries like path and fs Linux: NODE_PATH=. node app Windows: cmd.exe /C set NODE_PATH=.&& node app (On Windows this command will not work if you put a space in between the path and the &&. Crazy shit.) 6. The Start-up Script. Effectively, this solution also uses the environment (as in 5.2), it just abstracts it away There are basically two ways to reference the current folder in a Node.js script:./ __dirname; Along with ./, there is./, which points to the parent folder. They behave in the same way. There is a big difference between the two. Using __dirname in a Node script will return the path of the folder where the current JavaScript file resides

Select environment#. Depending on your environment, you need to use different import paths.Currently, two environments are supported: node — if you run the code in the Node.js; browser — if you run the code in a browser environment; Import for node environment The first argument in the fs.rename() method is currentPath where the file lives in, the second argument is the destinationPath and third argument is the callback function that runs with an err argument..

Implementing __dirname in ES6 modules using import.meta.url. ES6 modules are a nifty new way to write modules. In Node.js, our traditional CommonJS modules had several injected variables one of which, __dirname, was incredibly useful. None of those variables exist in ES6 modules. The Node.js team is working on replacements that work in ES6. I then changed it to go three levels up: fs.writeFileSync(path.join(__dirname,./../../configuration.json), ); This worked as expected; configuration.json was placed in the project root.Does this mean the path is determined from the class definition, and not the file where it is instantiated? I did not expect that behavior Summary: in this tutorial, you will learn about the path module in Node.js.

webpack-node-externals. In the first case I've set __dirname to false so when Webpack compile our server code it will not provide a polyfill and will keep the original value of __dirname, this configuration is useful when we serve static assets with Express, if we don't set it to false Express will not be able to find the reference for __dirname node a.js. you will see __dirname printed. Added background explanation: __dirname means 'The directory of this script'. In REPL, you don't have a script. Hence, __dirname would not have any real meaning. Questions: Answers: Building on the existing answers here, you could define this in your REPL: __dirname = path.resolve (path.dirname

While using webpack for server side packing of node.js apps I am unable to have an accurate value for __dirname when __dirname is called within a required module, regardless of what options.node.__dirname might be set to. If the current behavior is a bug, please provide the steps to reproduce. For example, assume the following: directory structur I have a working express file, which I 'webpack' it but when the bundled file is run the __dirname global changes to '/'. I need the absolute path for certain functions as res.sendFile process is node's global object, and .cwd() returns where node is running. __dirname is module's property, and represents the file path of the module. In node, one module resides in one file. Similarly, __filename is another module's property, which holds the file name of the module.
