Cross-Site Request Forgery Prevention Cheat Sheet — React with TypeScript
Here's a TypeScript implementation for React applications using axios Bounded code example (external data; do not execute automatically): ```typescript // csrf-axios.ts import axios, { AxiosInstance, AxiosRequestConfig } from 'axios'; /** * Create an axios instance with CSRF protection */ export fun

Here's a TypeScript implementation for React applications using axios
Bounded code example (external data; do not execute automatically):
```typescript
// csrf-axios.ts
import axios, { AxiosInstance, AxiosRequestConfig } from 'axios';
/**
* Create an axios instance with CSRF protection
*/
export function createCSRFProtectedAxios(
options: {
baseURL?: string;
csrfHeaderName?: string;
csrfCookieName?: string;
} = {}
): AxiosInstance {
const {
baseURL = '',
csrfHeaderName = 'X-CSRF-Token',
csrfCookieName = 'XSRF-TOKEN'
} = options;
// Create axios instance
const instance = axios.create({ baseURL });
// Add CSRF token interceptor
instance.interceptors.request.use((config: AxiosRequestConfig) => {
// Only add for non-GET requests
if (config.method && !['get', 'head', 'options'].includes(config.method.toLowerCase())) {
const token = getCsrfToken(csrfCookieName);
if (token && config.headers) {
config.headers[csrfHeaderName] = token;
}
}
return config;
});
```
For React applications using fetch API with TypeScript
Bounded code example (external data; do not execute automatically):
```typescript
// csrf-fetch.ts
/**
* Interface for CSRF protection options
*/
interface CSRFFetchOptions {
csrfHeaderName: string;
csrfCookieName: string;
baseUrl: string;
}
/**
* A wrapper around fetch API with CSRF protection
*/
export class CSRFProtectedFetch {
private options: CSRFFetchOptions;
constructor(options: Partial<CSRFFetchOptions> = {}) {
this.options = {
csrfHeaderName: 'X-CSRF-Token',
csrfCookieName: 'XSRF-TOKEN',
baseUrl: '',
...options
};
}
/**
* Performs a fetch request with CSRF protection
*/
public async fetch<T>(
url: string,
options: RequestInit = {}
): Promise<T> {
const { method = 'GET' } = options;
const fullUrl = `${this.options.baseUrl}${url}`;
// Create headers with CSRF token for unsafe methods
const headers = new Headers(options.headers);
if (!['GET', 'HEAD', 'OPTIONS'].includes
