# simple-nodejs-threader

A basic package for multithreading (multiple processes) in NodeJs

## Why

To simplify `node` build processes, used for better development experience or to spead up build pipelines, by utilizing node's multicore processing.

## Download

- With yarn: `yarn add -D simple-nodejs-threader`
- With npm: `npm install simple-nodejs-threader --save-dev`

## Getting started

1. Create a new Process manager

```typescript
const manager = new ProcessManager("My task name");
```

1. Create one or more processes that can run in parallel

```typescript
const backendProcess = ProcessManager.promiseSpawn(
  "yarn start:backend",
  [processFlags],
  {
    stdio: "inherit",
    shell: true,
  }
);

const frontendProcess = ProcessManager.promiseSpawn(
  "yarn start:frontend",
  [processFlags],
  {
    stdio: "inherit",
    shell: true,
  }
);
```

1. Add processes to the manager queue

```typescript
manager.queue(frontendProcess, backendProcess);
```

1. Await for completion

```typescript
await manager.complete();
```

## Utils

### addFlags

Convert an object into Node friendly process flags.

#### Arguments

- flags [`Record<string, string>`]

#### Usage

```typescript
const processFlags = addFlags({ argOne: "hello", argTwo: "world" });
processFlags; // [--hello, --world]
```

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.
