NOTE: While this is a fork of samdenty/console-feed it will not be compatible with the original project and will likely diverge. Please consider using the original module instead.

A React component that displays console logs from the current page, an iframe or transported across a server.



  • Console formatting - style and give your logs color, and makes links clickable
  • DOM nodes - easily inspect & expand HTML elements, with syntax highlighting
  • console.table - view your logs in a table format
  • Other console methods:
    • console.time - view the time in milliseconds it takes to complete events
    • console.assert - assert that a statement is truthy
    • console.count - count how many times something occurs
  • Inbuilt JSON serialization - Objects, Functions & DOM elements can be encoded / decoded to and from JSON


yarn add console-feed
# or
npm install console-feed

Basic usage

import React from 'react'
import { Hook, Console, Decode } from '@krismuniz/console-feed'

class App extends React.Component {
  state = {
    logs: [],

  componentDidMount() {
    Hook(window.console, (log) => {
      this.setState(({ logs }) => ({ logs: [...logs, Decode(log)] }))

    console.log(`Hello world!`)

  render() {
    return (
      <div style={{ backgroundColor: '#242424' }}>
        <Console logs={this.state.logs} variant="dark" />

OR with hooks:

import React, { useState, useEffect } from 'react'
import { Console, Hook, Unhook } from '@krismuniz/console-feed'

const LogsContainer = () => {
  const [logs, setLogs] = useState([])

  // run once!
  useEffect(() => {
      (log) => setLogs((currLogs) => [...currLogs, log]),
    return () => Unhook(window.console)
  }, [])

  return <Console logs={logs} variant="dark" />

export { LogsContainer }

Props for <Console /> component

logs: Log[]

An array consisting of Log objects. Required

filter?: Methods[]

Filter the logs, only displaying messages of certain methods.

variant?: 'light' | 'dark'

Sets the font color for the component. Default - light

styles?: Styles

Defines the custom styles to use on the component - see Styles.d.ts

searchKeywords?: string

A string value to filter logs

logFilter?: Function

If you want to use a custom log filter function, you can provide your own implementation

Log methods

Each log has a method assigned to it. The method is used to determine the style of the message and for the filter prop.

type Methods =
  | 'log'
  | 'debug'
  | 'info'
  | 'warn'
  | 'error'
  | 'table'
  | 'clear'
  | 'time'
  | 'timeEnd'
  | 'count'
  | 'assert'

Log object

A log object consists of the following:

type Logs = Log[]

interface Log {
  // The log method
  method: Methods
  // The arguments passed to console API
  data: any[]


By default when you use the Hook() API, logs are serialized so that they will safely work with JSON.stringify. In order to restore a log back to format compatible with the <Console /> component, you need to call the Decode() method.

Disabling serialization

If the Hook function and the <Console /> component are on the same origin, you can disable serialization to increase performance.

  (log) => {
    this.setState(({ logs }) => ({ logs: [...logs, log] }))

Limiting serialization

You can limit the number of keys/elements included when serializing objects/arrays.

  (log) => {
    this.setState(({ logs }) => ({ logs: [...logs, log] }))
  100 // limit to 100 keys/elements
