> Run the Node.js binary no matter what
|
|
|
|
You can't always assume running `$ node file.js` will just work. The user might have the `node` binary in a non-standard location. They might be using a Node.js version manager like `nvm`, which is sourced in a subshell and not available from the outside. It also depends from where you're trying to run it. For example, GUI apps on macOS doesn't inherit the [`$PATH`](https://en.wikipedia.org/wiki/PATH_(variable)), so the `node` binary would not be found. Most projects that depend on Node.js just end up telling the user to manually set the full path to the `node` binary in some project specific settings. Now every project has to do this. [Ugh...](https://gist.github.com/cookrn/4015437) I prefer things to *just* work. With this module it will.
|
|
|
|
This Bash script uses some tricks to find the Node.js binary on your system and run it.
|
|
|
|
Can be used from any environment that can spawn a process (Shell, Python, Ruby, Swift, Objective-C, etc).
|
|
|
|
|
|
### npm
|
|
|
|
#### Install
|
|
|
|
```
|
|
$ npm install run-node
|
|
```
|
|
|
|
#### Usage
|
|
|
|
```
|
|
$ ./node_modules/.bin/run-node file.js
|
|
```
|
|
|
|
Or in an [npm run script](https://docs.npmjs.com/cli/run-script):
|
|
|
|
```json
|
|
{
|
|
"start": "run-node file.js"
|
|
}
|
|
```
|
|
|
|
### Manually
|
|
|
|
#### Install
|
|
|
|
Download the [run-node](run-node) file:
|
|
|
|
```
|
|
$ curl -sSLO https://github.com/sindresorhus/run-node/raw/master/run-node && chmod +x run-node
|
|
```
|
|
|
|
#### Usage
|
|
|
|
```
|
|
./run-node file.js
|
|
```
|
|
|
|
#### Customizable cache path and error message
|
|
|
|
The cache path and error message are defined by the `RUN_NODE_CACHE_PATH` and `RUN_NODE_ERROR_MSG` environment variables. You could use them in a script or add them to your `~.bashrc`.
|
|
|
|
Default config:
|
|
|
|
```sh
|
|
export RUN_NODE_ERROR_MSG="Couldn't find the Node.js binary. Ensure you have Node.js installed. Open an issue on https://github.com/sindresorhus/run-node"
|
|
export RUN_NODE_CACHE_PATH="/home/username/.node_path"
|
|
```
