+# @2o3t/process-manager
+
+Process manager for Nodejs.
+
+Ideas from https://github.com/Microsoft/vscode.
+
+## Installation
+
+```sh
+npm install @2o3t/process-manager
+```
+
+or
+
+```sh
+yarn add @2o3t/process-manager
+```
+
+## Usage
+
+**Client** (main process):
+
+```js
+const PM = require('@2o3t/process-manager');
+const client = new PM.Client(__dirname + '/sub-processes.js');
+const channel = client.getChannel('channelName');
+channel.call('info', {
+    // something
+}).then(data => {
+    console.log('data', data);
+});
+channel.listen('ccc')(aa => {
+    console.log('listen..', aa);
+});
+```
+
+
+**Server** (sub process):
+
+```js
+const PM = require('@2o3t/process-manager');
+const server = new PM.Server();
+const channel = new PM.ServerChannel({
+    info(arg) {
+        console.log('arg: ', arg);
+        return Promise.resolve(server.info);
+    },
+    ccc(emit) {
+        emit('100w');
+        emit('101w');
+        // server.dispose();
+        emit('102w');
+        emit('103w');
+        emit('104w');
+    },
+});
+console.log('server ok');
+server.registerChannel('channelName', channel);
+```
+
+## Options
+
+**`Client`** options in paramters
+
+**modulePath**: file path of sub process
+
+**options**: Object.
+
+| key | type | desc |
+|-----|-----|-----|
+| **serverName** | string | A descriptive name for the server this connection is to. Used in logging. |
+| **timeout**? | number | Time in millies before killing the ipc process. The next request after killing will start it again. |
+| **args**? | string[] | Arguments to the module to execute. |
+| **env**? | any | Environment key-value pairs to be passed to the process that gets spawned for the ipc. |
+| **debug**? | number | Allows to assign a debug port for debugging the application executed. |
+| **debugBrk**? | number | Allows to assign a debug port for debugging the application and breaking it on the first line. |
+| **freshExecArgv**? | boolean | See https://github.com/Microsoft/vscode/issues/27665 <br> * Allows to pass in fresh execArgv to the forked process such that it doesn't inherit them from `process.execArgv`. <br> * e.g. Launching the extension host process with `--inspect-brk=xxx` and then forking a process from the extension host results in the forked process inheriting `--inspect-brk=xxx`. |
+| **useQueue**? | boolean | Enables our createQueuedSender helper for this Client. Uses a queue when the internal Node.js queue is full of messages - see notes on that method. |
+
+
+
+**`Server`** options in paramters
+
+**options**: Object.
+
+| key | type | desc |
+|-----|-----|-----|
+| **timeoutDelay**? | number | They will timeout after `timeoutDelay`. |
