# cross-dirname
[Node.js](https://nodejs.org) + [Gjs](https://gjs.guide/) + [Deno](https://deno.land/) module that returns the current script dirname and filename. Similar to `__dirname` and `__filename` but also works in CommonJs and ES modules.
## Installation
On Node.js and GJS you can install the package as with NPM:
```
npm install cross-dirname --save
```
On Deno you just need to import this package:
```ts
import { getDirname, getFilename } from 'https://deno.land/x/cross_dirname/mod.ts';
```
## Usage
Please do not use `getDirname` and `getFilename` in nested other methods, instead always use them in the root of your file, otherwise it may return wrong results.
### Node.js ESM
```js
// /path/to/the/script.mjs
import { getDirname, getFilename } from 'cross-dirname'
console.log(getDirname()) // outputs "/path/to/the"
console.log(getFilename()) // outputs "/path/to/the/script.mjs"
```
### Node.js CJS
```js
// /path/to/the/script.cjs
const { getDirname, getFilename } = require('cross-dirname');
console.log(getDirname() === __dirname) // true
console.log(getFilename() === __filename) // true
```
### Deno
```ts
// /path/to/the/script.ts
import { getDirname, getFilename } from 'https://deno.land/x/cross_dirname@v0.0.4/mod.ts';
console.log(getDirname()); // outputs "/path/to/the"
console.log(getFilename()); // outputs "/path/to/the/script.ts"
```
### GJS
You can use NPM packages in GJS with a bundler like [esbuild](https://esbuild.github.io/).
Take a look at the examples for an [GJS + esbuild example](/examples/gjs), you can start the example like this:
```bash
# Install dev dependencies
npm install
# Go to the example
cd examples/gjs
# Bundle src/index.js
node esbuild.mjs
# Run the bundled index.js
gjs -m index.js
```
### Examples
You can run the examples with
```bash
npm install
npm run build
deno run ./examples/deno/index.ts
# -> /.../examples/deno
node ./examples/node/index.cjs
# -> /.../examples/node
node ./examples/node/index.mjs
# -> /.../examples/node
node ./examples/gjs/esbuild.mjs
gjs -m ./examples/gjs/index.js
# -> /.../examples/gjs
```
