# Node.js on Windows

Prerequisites:

          

- [Supported Node.js Technologies](https://docs.stackify.com/docs/supported-nodejs-technologies)  

*Since Prefix and Retrace share the same modules/profiler, the supported frameworks between the two products will be the same in most cases.*

### 1. Download and install the Prefix installation file:

Check out the [Getting Started](https://docs.stackify.com/v1/docs/prefix-getting-started) Prefix page to download and install Prefix on your workstation.

### 2. Get the latest Stackify Node.js Profiler for Prefix:

```
npm install stackify-node-apm --save
```

### 3. Configure the Application to use the Profiler with Prefix Enabled:

- Copy `node_modules/stackify-node-apm/stackify.js` into your application's root directory and modify **Application Name** and **Environment Name**.
- Add `prefix_enabled: true`to the **stackify.js** file.

```
/**
 * Stackify Node APM Configuration
 */
exports.config = {
  /**
   * Your application name.
   */
  application_name: 'Node Application',
  /**
   * Your environment name.
   */
  environment_name: 'Production',
  /**
   * Enable Prefix.
   */
   prefix_enabled: true
}
```

### 4. Initialize the Profiler:

- Add `require('stackify-node-apm')` to the top of your application's main module.

### 5. Verify application requests show up in Prefix
