+# vm2 [![NPM Version][npm-image]][npm-url] [![NPM Downloads][downloads-image]][downloads-url] [![Package Quality][quality-image]][quality-url] [![Travis CI][travis-image]][travis-url] [![Known Vulnerabilities][snyk-image]][snyk-url]
+
+vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Securely!
+
+**Features**
+
+* Runs untrusted code securely in a single process with your code side by side
+* Full control over sandbox's console output
+* Sandbox has limited access to process's methods
+* Sandbox can require modules (builtin and external)
+* You can limit access to certain (or all) builtin modules
+* You can securely call methods and exchange data and callbacks between sandboxes
+* Is immune to all known methods of attacks
+* Transpilers support
+
+**How does it work**
+
+* It uses internal VM module to create secure context
+* It uses [Proxies](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Proxy) to prevent escaping the sandbox
+* It overrides builtin require to control access to modules
+
+**What is the difference between Node's vm and vm2?**
+
+Try it yourself:
+
+```javascript
+const vm = require('vm');
+vm.runInNewContext('this.constructor.constructor("return process")().exit()');
+console.log('Never gets executed.');
+```
+
+```javascript
+const {VM} = require('vm2');
+new VM().run('this.constructor.constructor("return process")().exit()');
+// Throws ReferenceError: process is not defined
+```
+
+## Installation
+
+**IMPORTANT**: Requires Node.js 6 or newer.
+
+    npm install vm2
+
+## Quick Example
+
+```javascript
+const {VM} = require('vm2');
+const vm = new VM();
+
+vm.run(`process.exit()`); // TypeError: process.exit is not a function
+```
+
+```javascript
+const {NodeVM} = require('vm2');
+const vm = new NodeVM({
+    require: {
+        external: true
+    }
+});
+
+vm.run(`
+    var request = require('request');
+    request('http://www.google.com', function (error, response, body) {
+        console.error(error);
+        if (!error && response.statusCode == 200) {
+            console.log(body) // Show the HTML for the Google homepage.
+        }
+    })
+`, 'vm.js');
+```

+
+## VM
+
+VM is a simple sandbox, without `require` feature, to synchronously run an untrusted code. Only JavaScript built-in objects + Buffer are available. Scheduling functions (`setInterval`, `setTimeout` and `setImmediate`) are not available by default.
+
+**Options:**
+
+* `timeout` - Script timeout in milliseconds.
+* `sandbox` - VM's global object.
+* `compiler` - `javascript` (default) or `coffeescript` or custom compiler function. The library expects you to have coffee-script pre-installed if the compiler is set to `coffeescript`.
+* `eval` - If set to `false` any calls to `eval` or function constructors (`Function`, `GeneratorFunction`, etc) will throw an `EvalError` (default: `true`).
+* `wasm` -  If set to `false` any attempt to compile a WebAssembly module will throw a `WebAssembly.CompileError` (default: `true`).
+* `fixAsync` - If set to `true` any attempt to run code using async will throw a `VMError` (default: `false`).
+
+**IMPORTANT**: Timeout is only effective on synchronous code you run through `run`. Timeout is NOT effective on any method returned by VM. There're some situations when timeout doesn't work - see [#244](https://github.com/patriksimek/vm2/pull/244).
+
+```javascript
+const {VM} = require('vm2');
+
+const vm = new VM({
+    timeout: 1000,
+    sandbox: {}
+});
+
+vm.run("process.exit()"); // throws ReferenceError: process is not defined
+```
+
+You can also retrieve values from VM.
+
+```javascript
+let number = vm.run("1337"); // returns 1337
+```
+
+**TIP**: See tests for more usage examples.
+
+## NodeVM
+
+Unlike `VM`, `NodeVM` lets you require modules same way like in regular Node's context.
+
+**Options:**
+
+* `console` - `inherit` to enable console, `redirect` to redirect to events, `off` to disable console (default: `inherit`).
+* `sandbox` - VM's global object.
+* `compiler` - `javascript` (default) or `coffeescript` or custom compiler function (which receives the code, and it's filepath). The library expects you to have coffee-script pre-installed if the compiler is set to `coffeescript`.
+* `eval` - If set to `false` any calls to `eval` or function constructors (`Function`, `GeneratorFunction`, etc) will throw an `EvalError` (default: `true`).
+* `wasm` -  If set to `false` any attempt to compile a WebAssembly module will throw a `WebAssembly.CompileError` (default: `true`).
+* `sourceExtensions` - Array of file extensions to treat as source code (default: `['js']`).
+* `require` - `true` or object to enable `require` method (default: `false`).
+* `require.external` - `true`, an array of allowed external modules or an object (default: `false`).
+* `require.external.modules` - Array of allowed external modules. Also supports wildcards, so specifying `['@scope/*-ver-??]`, for instance, will allow using all modules having a name of the form `@scope/something-ver-aa`, `@scope/other-ver-11`, etc.
+* `require.external.transitive` - Boolean which indicates if transitive dependencies of external modules are allowed (default: `false`).
+* `require.builtin` - Array of allowed builtin modules, accepts ["*"] for all (default: none).
+* `require.root` - Restricted path(s) where local modules can be required (default: every path).
+* `require.mock` - Collection of mock modules (both external or builtin).
+* `require.context` - `host` (default) to require modules in host and proxy them to sandbox. `sandbox` to load, compile and require modules in sandbox. Builtin modules except `events` always required in host and proxied to sandbox.
+* `require.import` - Array of modules to be loaded into NodeVM on start.
+* `require.resolve` - An additional lookup function in case a module wasn't found in one of the traditional node lookup paths.
+* `nesting` - `true` to enable VMs nesting (default: `false`).
+* `wrapper` - `commonjs` (default) to wrap script into CommonJS wrapper, `none` to retrieve value returned by the script.
+* `argv` - Array to be passed to `process.argv`.
+* `env` - Object to be passed to `process.env`.
+* `strict` - `true` to loaded modules in strict mode (default: `false`).
+
+**IMPORTANT**: Timeout is not effective for NodeVM so it is not immune to `while (true) {}` or similar evil.
+
+**REMEMBER**: The more modules you allow, the more fragile your sandbox becomes.
+
+```javascript
+const {NodeVM} = require('vm2');
+
+const vm = new NodeVM({
+    console: 'inherit',
+    sandbox: {},
+    require: {
+        external: true,
+        builtin: ['fs', 'path'],
+        root: "./",
+        mock: {
+            fs: {
+                readFileSync() { return 'Nice try!'; }
+            }
+        }
+    }
+});
+
+// Sync
+
+let functionInSandbox = vm.run("module.exports = function(who) { console.log('hello '+ who); }");
+functionInSandbox('world');
+
+// Async
+
+let functionWithCallbackInSandbox = vm.run("module.exports = function(who, callback) { callback('hello '+ who); }");
+functionWithCallbackInSandbox('world', (greeting) => {
+    console.log(greeting);
+});
+```
+
+When `wrapper` is set to `none`, `NodeVM` behaves more like `VM` for synchronous code.
+
+```javascript
+assert.ok(vm.run('return true') === true);
+```
+
+**TIP**: See tests for more usage examples.
+
+### Loading modules by relative path
+
+To load modules by relative path, you must pass full path of the script you're running as a second argument of vm's `run` method if the script is a string. Filename then also shows up in any stack traces produced from the script.
+
+```javascript
+vm.run("require('foobar')", "/data/myvmscript.js");
+```
+
+If the script you are running is an VMScript, the path is given in the VMScript constructor.
+
+```javascript
+const script = new VMScript("require('foobar')", {filename: "/data/myvmscript.js"});
+vm.run(script);
+```
+
+## VMScript
+
+You can increase performance by using pre-compiled scripts. The pre-compiled VMScript can be run later multiple times. It is important to note that the code is not bound to any VM (context); rather, it is bound before each run, just for that run.
+
+```javascript
+const {VM, VMScript} = require('vm2');
+
+const vm = new VM();
+const script = new VMScript("Math.random()");
+console.log(vm.run(script));
+console.log(vm.run(script));
+```
+
+Works for both `VM` and `NodeVM`.
+
+```javascript
+const {NodeVM, VMScript} = require('vm2');
+
+const vm = new NodeVM();
+const script = new VMScript("module.exports = Math.random()");
+console.log(vm.run(script));
+console.log(vm.run(script));
+```
+
+Code is compiled automatically first time you run it. You can compile the code anytime with `script.compile()`. Once the code is compiled, the method has no effect.
+
+## Error handling
+
+Errors in code compilation and synchronous code execution can be handled by `try`/`catch`. Errors in asynchronous code execution can be handled by attaching `uncaughtException` event handler to Node's `process`.
+
+```javascript
+try {
+    var script = new VMScript("Math.random()").compile();
+} catch (err) {
+    console.error('Failed to compile script.', err);
+}
+
+try {
+    vm.run(script);
+} catch (err) {
+    console.error('Failed to execute script.', err);
+}
+
+process.on('uncaughtException', (err) => {
+    console.error('Asynchronous error caught.', err);
+})
+```
+
+## Debugging a sandboxed code
+
+You can debug/inspect code running in the sandbox as if it was running in a normal process.
+
+- You can use breakpoints (requires you to specify a script file name)
+- You can use `debugger` keyword.
+- You can use step-in to step inside the code running in the sandbox.
+
+**Example**
+
+/tmp/main.js:
+```javascript
+const {VM, VMScript} = require('.');
+const fs = require('fs');
+const file = `${__dirname}/sandbox.js`;
+
+// By providing a file name as second argument you enable breakpoints
+const script = new VMScript(fs.readFileSync(file), file);
+
+new VM().run(script);
+```
+
+/tmp/sandbox.js
+```javascript
+const foo = 'ahoj';
+
+// Debugger keyword works just fine anywhere.
+// Even without specifying a file name to the VMScript object.
+debugger;
+```
+
+## Read-only objects (experimental)
+
+To prevent sandboxed script to add/change/delete properties to/from the proxied objects, you can use `freeze` methods to make the object read-only. This is only effective inside VM. Frozen objects are affected deeply. Primitive types can not be frozen.
+
+**Example without using `freeze`:**
+
+```javascript
+const util = {
+    add: (a, b) => a + b
+}
+
+const vm = new VM({
+    sandbox: {util}
+});
+
+vm.run('util.add = (a, b) => a - b');
+console.log(util.add(1, 1)); // returns 0
+```
+
+**Example with using `freeze`:**
+
+```javascript
+const vm = new VM(); // Objects specified in sandbox can not be frozen.
+vm.freeze(util, 'util'); // Second argument adds object to global.
+
+vm.run('util.add = (a, b) => a - b'); // Fails silently when not in strict mode.
+console.log(util.add(1, 1)); // returns 2
+```
+
+**IMPORTANT:** It is not possible to freeze objects that has already been proxied to the VM.
+
+## Protected objects (experimental)
+
+Unlike `freeze`, this method allows sandboxed script to add/modify/delete properties on object with one exception - it is not possible to attach functions. Sandboxed script is therefore not able to modify methods like `toJSON`, `toString` or `inspect`.
+
+**IMPORTANT:** It is not possible to protect objects that has already been proxied to the VM.
+
+## Cross-sandbox relationships
+
+```javascript
+const assert = require('assert');
+const {VM} = require('vm2');
+
+const sandbox = {
+    object: new Object(),
+    func: new Function(),
+    buffer: new Buffer([0x01, 0x05])
+}
+
+const vm = new VM({sandbox});
+
+assert.ok(vm.run(`object`) === sandbox.object);
+assert.ok(vm.run(`object instanceof Object`));
+assert.ok(vm.run(`object`) instanceof Object);
+assert.ok(vm.run(`object.__proto__ === Object.prototype`));
+assert.ok(vm.run(`object`).__proto__ === Object.prototype);
+
+assert.ok(vm.run(`func`) === sandbox.func);
+assert.ok(vm.run(`func instanceof Function`));
+assert.ok(vm.run(`func`) instanceof Function);
+assert.ok(vm.run(`func.__proto__ === Function.prototype`));
+assert.ok(vm.run(`func`).__proto__ === Function.prototype);
+
+assert.ok(vm.run(`new func() instanceof func`));
+assert.ok(vm.run(`new func()`) instanceof sandbox.func);
+assert.ok(vm.run(`new func().__proto__ === func.prototype`));
+assert.ok(vm.run(`new func()`).__proto__ === sandbox.func.prototype);
+
+assert.ok(vm.run(`buffer`) === sandbox.buffer);
+assert.ok(vm.run(`buffer instanceof Buffer`));
+assert.ok(vm.run(`buffer`) instanceof Buffer);
+assert.ok(vm.run(`buffer.__proto__ === Buffer.prototype`));
+assert.ok(vm.run(`buffer`).__proto__ === Buffer.prototype);
+assert.ok(vm.run(`buffer.slice(0, 1) instanceof Buffer`));
+assert.ok(vm.run(`buffer.slice(0, 1)`) instanceof Buffer);
+```
+
+## CLI
+
+Before you can use vm2 in command line, install it globally with `npm install vm2 -g`.
+
+```
+$ vm2 ./script.js
+```
+
+## Known Issues
+
+* It is not possible to define class that extends proxied class.
+
+## Deployment
+
+1. Update the CHANGELOG
