# Run multiple concurrent processes
|
|
|
|
Do you run an application that needs multiple processes? Like `npm run dev` and `npm run tailwind`. Typically in a dev environment you would need to have more than one terminal open if you're running more than on processes. But with batch run you only need one terminal to run all processes concurrently.
|
|
|
|
## Installation
|
|
|
|
You can install and run this package directly by running:
|
|
|
|
```bash
|
|
npx batchrun "npm run dev, npm run tailwind"
|
|
```
|
|
|
|
To install this module globally simply run:
|
|
|
|
```bash
|
|
npm install -g batchrun
|
|
```
|
|
|
|
To install this module locally(for just the project) run:
|
|
|
|
```bash
|
|
npm install batchrun
|
|
```
|
|
|
|
_NOTE_: You will have to append `npx` to your command for just a local installation.
|
|
|
|
## Requirements
|
|
|
|
For this package to work you need an argument of strings in the terminal command, or a `batchrun.config.json` file at the root of your project directory, which is simply an array of strings, each string being the command to run. Example:
|
|
|
|
```json
|
|
["node index.js", "npm run tailwind"]
|
|
```
|
|
|
|
More entries mean more processes.
|
|
|
|
# Usage
|
|
|
|
To fire up the process without a `batchrun.config.json` file simply run:
|
|
|
|
```bash
|
|
batchrun "npm run dev, npm run tailwind"
|
|
```
|
|
|
|
If you did not install the package globally, run:
|
|
|
|
```bash
|
|
npx batchrun "npm run dev, npm run tailwind"
|
|
```
|
|
|
|
If you already have a `batchrun.config.json` file just run
|
|
|
|
```bash
|
|
batchrun
|
|
```
|
|
|
|
# Process actions
|
|
|
|
When your process is up and running, you can perform a few more actions to your running processes.
|
|
|
|
### Reload all processes
|
|
|
|
To reload all processes, while the process is active in your terminal type
|
|
|
|
```bash
|
|
reload
|
|
```
|
|
|
|
Press `Enter` after tyring this. This will reload all the processes you started. Alternatively, you can simply press `Ctrl+R`: this does the same thing. `restart` amd `reboot` commands work also.
|
|
|
|
### Reload processes
|
|
|
|
You can also target a single process and reload it. This will need an index appended to the `reload` command. Example:
|
|
|
|
```bash
|
|
- Processes Started ...
|
|
...
|
|
reload 0
|
|
```
|
|
|
|
This will reload the first command in your list of commands. You can add more indexes by separating them with a comma(,): Example:
|
|
|
|
```bash
|
|
- Processes Started ...
|
|
...
|
|
reload 0,3,4
|
|
```
|
|
|
|
_NOTE_: Do not add a space between the commands or else the `reload` command won't work.
|
|
|
|
### Kill processes
|
|
|
|
To kill all processes simply type:
|
|
|
|
```bash
|
|
- Processes Started ...
|
|
...
|
|
kill
|
|
```
|
|
|
|
This is the equivalent of pressing `Ctrl+C`. To kill specific processes just follow the same convention as the `reload` command. Example:
|
|
|
|
```bash
|
|
- Processes Started ...
|
|
...
|
|
kill 1,2
|
|
```
|
|
|
|
To restart a killed process simple use the `reload` command again.
