Parse Data Configuration

The Parse Data middleware provides a range of configuration options to customize its behavior. These options allow you to control which types of data are parsed and enable additional features like SQL injection prevention.

Default Configuration

By default, the Parse Data middleware is configured as follows:

{
  urlencoded: true,  // Enables parsing of URL-encoded form data
  params: true,      // Enables parsing of URL parameters
  query: true,       // Enables parsing of query parameters
  json: true,        // Enables parsing of JSON body data
  formData: true,    // Enables parsing of multipart/form-data (including file uploads)
  escapeSQL: false   // Disables SQL escaping by default
}

This default setup ensures compatibility with most use cases while maintaining performance and security.

Configuration Options

Here are the available options for configuring Parse Data:

1. urlencoded (boolean):

   • Enables or disables parsing of URL-encoded form data.
   • Default: true.

2. params (boolean):

   • Enables or disables parsing of URL parameters.
   • Default: true.

3. query (boolean):

   • Enables or disables parsing of query string parameters.
   • Default: true.

4. json (boolean):

   • Enables or disables parsing of JSON data in the request body.
   • Default: true.

5. formData (boolean):

   • Enables or disables parsing of multipart form data (including file uploads).
   • Default: true.

6. escapeSQL (boolean):

   • If enabled, all parsed strings are sanitized to prevent SQL injection attacks.
   • Default: false.

Custom Configuration Example

To apply custom configurations, pass an options object to the parseData middleware:

import v from "vkrun"
 
const app = v.App()
 
app.parseData({
  urlencoded: true, // Enable URL-encoded form data parsing
  params: false,    // Disable URL parameters parsing
  query: true,      // Enable query string parsing
  json: false,      // Disable JSON body parsing
  formData: true,   // Enable multipart form data parsing
  escapeSQL: true   // Enable SQL injection prevention
})
 
app.get("/example", (request: v.Request, response: v.Response) => {
  response.status(200).json({ message: "Custom Parse Data configuration applied!" })
})
 
app.server().listen(3000, () => {
  console.log("Server started with custom Parse Data configuration")
})
