EMACS JS DEBUGGING WITH INDIUM

1. indium requires a config file to be setup `.indium.json`
2. M-x indium-launch

The `.indium.json` file can contain as many configurations as needed, and mix any supported configuration types.

The currently supported `type` values are `"chrome"` and `"node"`.

The root directory of the source files is by default set to the directory where this `.indium.json` file is placed, but it can be overridden with the `root` (or the `webRoot` alias) option:

BACK-END (node mode)

| program:     | Nodejs program to start a new process. The `--inspect` flag will be added automatically. Expected type: string. |
| :----------- | ------------------------------------------------------------ |
| args:        | Arguments passed to the program to debug. Expected type: string. |
| inspect-brk: | Whether Indium should break at the first statement (false by default). |
| host:        | Host on which the Node inspector is listening (defaults to `"localhost"`). |
| port:        | Port on which the Node inspector is listening (defaults to 9229). |

```
{
  "configurations": [
    {
      "name": "11ty",
      "type": "node",
      "program": "node",
      "args": "./node_modules/.bin/eleventy",
      "inspect-brk": true
    }
  ]
}

```

FRONT-END(chrome)

| host: | Host on which Chrome is running (defaults to `"localhost"`). |
| :---- | ------------------------------------------------------------ |
| port: | Port on which Chrome is running (defaults to `9222`).        |
| url:  | Url to open when running `indium-launch`.                    |

```
{
  "configurations": [
    {
      "name": "Web project",
      "type": "chrome",
      "host": "127.0.0.1",
      "url": "http://127.0.0.1/",
      "port": 9222
    }
  ]
}
```

## Starting Indium

Indium can be started in two modes:

- Connect: `M-x indium-connect` Connect indium to a running runtime from one of the configurations in the `.indium.json` project file.
- Launch: `M-x indium-launch` Start a JavaScript process (Chrome or NodeJS) as specified from the configurations in the `.indium.json` project file.

NOTES:

snap chrome allows chromium cli call

Append

```bash
alias chromium="flatpak run org.chromium.Chromium"
```

to your `~/.bashrc` file

(setq indium-chrome-executable "chrome")
