handleConsole

Intercept and handle console method calls, can execute custom logic before/after console output.

API

handleConsole

Return

No return value (void)

Parameters

Parameter	Description	Type	Default
hooks	Intercept callback function	Function	noop

hooks Parameters

Callback function receives the following parameters:

• type: Console method type ('log', 'info', 'warn', 'error', 'assert')
• ...args: Arguments passed to console method

Example

Basic Usage

import { handleConsole } from 'ranuts';

handleConsole((type, ...args) => {
  console.log(`[${type}]`, ...args);
  // Can log here, send to server, etc.
});

Log Collection

import { handleConsole } from 'ranuts';

const logs = [];

handleConsole((type, ...args) => {
  logs.push({
    type,
    args,
    timestamp: Date.now(),
  });
});

// Can send logs to server later

Filter Sensitive Information

import { handleConsole } from 'ranuts';

handleConsole((type, ...args) => {
  // Filter sensitive information
  const filtered = args.map((arg) => {
    if (typeof arg === 'string' && arg.includes('password')) {
      return '[FILTERED]';
    }
    return arg;
  });
  console[type](...filtered);
});

Error Reporting

import { handleConsole } from 'ranuts';

handleConsole((type, ...args) => {
  if (type === 'error') {
    // Report error to server
    reportError(args);
  }
});

Notes

1. Intercepted methods: Intercepts five console methods: log, info, warn, error, assert.
2. Original method preserved: After interception, original console method still executes, just adds hooks.
3. Parameter passing: Callback function receives method type and all original parameters.
4. Use case: Commonly used for log collection, error monitoring, debugging tools, etc.
