      <h1>ESP Web Tools</h1>
      <p>
        ESP Web Tools is a set of open source tools to allow working with ESP
        devices in the browser.
        <a href="https://github.com/esphome/esp-web-tools"
          >The code is available on GitHub.</a
        >
      </p>
      <p>
        To try it out and install
        <a href="https://esphome.io">ESPHome</a> on an ESP, connect it to your
        computer and hit the button:
      </p>
      <esp-web-install-button
        manifest="static/firmware_build/manifest.json"
      ></esp-web-install-button>
      <p>
        <i>
          Note, this only works in desktop Chrome and Edge. Android support
          should be possible but has not been implemented yet. If you don't see
          your ESP device, you might miss <a href="#drivers">drivers</a>.
        </i>
      </p>
      <p>
        This works by combining
        <a
          href="https://developer.mozilla.org/en-US/docs/Web/API/Web_Serial_API"
          >Web Serial</a
        >
        with a manifest which describes the firmware. It will automatically
        detect the type of the connected ESP device and find the right firmware
        files in the manifest.

        To add this to your own website, create a manifest and add the button to

        your manifest.
      </p>
      <p>
        You can import ESP Web Tools directly from the unpkg CDN or
        <a href="https://unpkg.com/browse/esp-web-tools/dist/web/"
          >download the files</a
        >

      <p>
        Your website needs to be served over <code>https://</code>. If your
        manifest is hosted on another server, make sure you configure
        <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS"
          >the CORS-headers</a
        >
        for your manifest and firmware files such that your website is allowed
        to fetch those files by adding the header
        <code
          >Access-Control-Allow-Origin: https://domain-of-your-website.com</code
        >.
      </p>

      <p>
        ESP Web Tools can also be integrated in your projects by installing it
        via NPM:<br />
        <code>npm install --save esp-web-tools</code>
      </p>
      <h3 id="manifest">Creating your manifest</h3>
      <p>
        ESP Web Tools manifest describe the firmware that you want to install.
        It allows specifying different builds for the different types of ESP
        devices. Current supported chip families are <code>ESP8266</code>,
        <code>ESP32</code>, <code>ESP32C3</code> and <code>ESP32S2</code>. The
        correct build will be automatically selected based on the type of the
        ESP device we detect via the serial port.
      </p>
      <pre>
{
  "name": "ESPHome",
  "version": "2021.11.0",
  "home_assistant_domain": "esphome",
  "new_install_skip_erase": false,
  "builds": [
    {
      "chipFamily": "ESP32",
      "parts": [
        { "path": "bootloader.bin", "offset": 4096 },
        { "path": "partitions.bin", "offset": 32768 },
        { "path": "ota.bin", "offset": 57344 },
        { "path": "firmware.bin", "offset": 65536 }
      ]
    },
    {
      "chipFamily": "ESP8266",
      "parts": [
        { "path": "esp8266.bin", "offset": 0 }
      ]
    }
  ]
}</pre
      >
      <p>
        Each build contains a list of parts to be flashed to the ESP device.
        Each part consists of a path to the file and an offset on the flash
        where it should be installed. Part paths are resolved relative to the
        path of the manifest, but can also be URLs to other hosts.
      </p>
      <p>
        If your firmware is supported by Home Assistant, you can add the
        optional key <code>home_assistant_domain</code>. If present, ESP Web
        Tools will link the user to add this device to Home Assistant.
      </p>
      <p>
        By default a new installation will erase the entire flash. If you want
        to skip this step, set the optional key
        <code>new_install_skip_erase</code> to <code>true</code>. ESP Web Tools
        considers it a new installation if it is unable to detect the current
        firmware of the device (via Improv Serial) or if the detected firmware
        does not match the name specififed in the manifest.
      </p>
      <h3 id="improv">Wi-Fi provisioning</h3>
      <p>
        ESP Web Tools has support for the
        <a href="https://www.improv-wifi.com/serial"
          >Improv Wi-Fi serial standard</a
        >. This is an open standard to allow configuring Wi-Fi via the serial
        port.
      </p>
      <p>
        If Improv is supported, a user will be guided to connect the device to
        the network after installation. It also allows the user to connect
        already installed devices and re-configure the wireless network
        settings.
      </p>

      <h3 id="customize">Customizing the look and feel</h3>
      <p>
        There are multiple options to change the look and feel of the button and
        other elements.
      </p>
      <h4>Change colors</h4>
      <p>
        You can change the colors of the default UI elements with CSS custom
        properties (variables), the following variables are available:
      </p>
      <ul>
        <li><code>--esp-tools-button-color</code></li>
        <li><code>--esp-tools-button-text-color</code></li>
      </ul>
      <p>There are also some attributes that can be used for styling:</p>
      <table>
        <tr>
          <td><code>install-supported</code></td>
          <td>Added if installing firmware is supported</td>
        </tr>
        <tr>
          <td>
            <code>install-unsupported</code>
          </td>
          <td>Added if installing firmware is not supported</td>
        </tr>
      </table>
      <h4>Replace the button and message with a custom one</h4>
      <p>
        You can replace both the activation button and the message that is shown
        when the user uses an unsupported browser or non-secure context with
        your own elements. This can be done using the <code>activate</code>,
        <code>unsupported</code> and <code>not-allowed</code> slots:
      </p>
      <pre>
&lt;esp-web-install-button
  manifest="static/firmware_build/manifest.json"
>
  &lt;button slot="activate">Custom install button&lt;/button>
  &lt;span slot="unsupported">Ah snap, your browser doesn't work!&lt;/span>
  &lt;span slot="not-allowed">Ah snap, you are not allowed to use this on HTTP!&lt;/span>
&lt;/esp-web-install-button>
    </pre
      >
      <h3 id="drivers">USB Serial Drivers</h3>
      <p>
        If the serial port is not showing up, your computer might be missing the
        drivers for the USB serial chip used in your ESP device. These drivers
        work for most ESP devices:
      </p>
      <ul>
