### 1)История.Причины.

---


---

## Content script

- Bind with each page
- Manipulate DOM
- Add event listeners
- Isolated JavaScript environment
- It doesn't break things

---

# :fork_and_knife:

---

<style>
code.blue {
color: #337AB7 !important;
}
code.orange {
color: #F7A004 !important;
}
</style>

- <code class="orange">onMessage('event')</code>: Register event listener
- <code class="blue">sendMessage('event')</code>: Trigger event

---

# :bulb:

---

- Dead simple API
- Only cares about application logic

---

import * as Channeru from 'channeru'

// setup channel in different page environment, once
const channel = Channeru.create()

---

// in background script
const fakeLogin = async () => true

channel.answer('isLogin', async () => {
  return await fakeLogin()
})

<br>

// in inject script
const isLogin = await channel.callBackground('isLogin')
console.log(isLogin) //-> true
