# SolidityScan

Secure your Solidity smart contracts straight from your terminal or JavaScript code! **SolidityScan** is a lightweight CLI and Node.js library that connects to the [CredShields SolidityScan](https://solidityscan.com) API to identify vulnerabilities, gas optimisations, and other issues in your smart-contract projects.

## Features

• 📦 **Local Directory Scanning** – Zip and upload your local Solidity source code and get instant feedback in the terminal.<br/>
• ⚡ **Real-time Progress** – Live WebSocket updates with an elegant spinner so you always know the scan status.<br/>
• 📋 **Readable Reports** – Vulnerabilities and severities are displayed in coloured, column-aligned tables, followed by a concise scan summary.
• 🌐 **Local WebSocket File Server** – Spin up a file server for quick web-UI integrations and demos.

## Installation

```bash
# Install globally to use the `solidityscan` CLI
yarn global add solidityscan        # or npm install -g solidityscan

# Add to a project for programmatic use
npm install solidityscan --save     # or yarn add solidityscan
```

> **Requirement**: Node.js >= 14

## Getting an API Key

1. Sign up or log in at [solidityscan.com](https://solidityscan.com).
2. Navigate to **API Keys** and generate a new key.
3. Either export it as an environment variable:

```bash
export SOLIDITYSCAN_API_KEY="YOUR_API_KEY"
```

…or pass it as the last argument in each CLI command (see below).

---

## CLI Usage

After installing globally you will have a `solidityscan` binary in your PATH.
Run `solidityscan --help` to view the brief usage guide.

---

### Scan a Local Directory

Analyse a local folder containing `.sol` files. The tool packages the Solidity source, uploads it, waits for the scan to finish and prints the results.

If using with API key in terminal command.

```bash
solidityscan local /path/to/my/contracts [api-key] [project-name]
```

If using with API key in environment variable.

```bash
solidityscan local /path/to/my/contracts [project-name]
```

If no project name is provided, it will default to "LocalScan".

---

### Run a Local File Server

Start a WebSocket file server to expose your local directory to the SolidityScan web-UI
A unique **identifier** (\`--id\`) is mandatory – this becomes the sub-domain of the temporary public URL.

```bash
# Serve current directory on default port 9462 (or 9463-9466 if 9462 is busy)
solidityscan -l --id <id-from-solidityscan>

# Serve a specific directory
solidityscan -l -p /my/contracts --id <id-from-solidityscan>

# Bind to an explicit port instead of the automatic range
solidityscan -l -p ./src --id <id-from-solidityscan> --port 9000
```

Behaviour notes:

* If **--port** is omitted the CLI tries to bind to 9462 and, if in use, increments the port up to 5 times (9462-9466).
* The **identifier** should be exactly the string shown on SolidityScan's **Connect&nbsp;to&nbsp;Localhost** page – copy it from the web-UI and use it with `--id`.

---

## Programmatic Usage

You can also integrate SolidityScan directly into your Node.js scripts or CI pipelines:

```js
const solidityscan = require("solidityscan");

(async () => {
  const apiToken = process.env.SOLIDITYSCAN_API_KEY;

  // Scan a local directory (same behaviour as CLI `test`)
  await solidityscan.runTests("./contracts", apiToken);
})();
```

Available exported helpers:

* `runTests(directoryPath, apiToken)`
* `scan()` – executes the CLI with current `process.argv` (internally used by the binary).

## Examples

You can find full working examples inside the [`examples/`](https://github.com/Credshields/solidityscan-npm-package/tree/main/examples) directory (coming soon).
