<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">the ESPHome firmware</a>, connect an ESP to
your computer and hit the button:
</p>
<esp-web-install-button
manifest="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.
</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.
</p>
<h2>Using ESP Web Tools on your website</h2>
<p>
To add this to your own website, create a manifest and add the button to
your website. Make sure you update the manifest attribute to point at
your manifest.
</p>
<pre>
&lt;script
type="module"
src="https://unpkg.com/esp-web-tools@1.0.3/dist/web/install-button.js?module"
>&lt;/script>
&lt;esp-web-install-button
manifest="firmware_build/manifest.json"
>&lt;/esp-web-install-button></pre
>
<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>
Add the attribute <code>erase-first</code> if you want to first fully
erase the ESP prior to installation.
</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 devices are ESP8266, ESP32 and ESP32-S2. 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",
"builds": [
{
"chipFamily": "ESP32",
"improv": true,
"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>
Each build also allows you to specify if it supports
<a href="https://www.improv-wifi.com">the Improv WiFi standard</a>. If
it does, the user will be offered to configure the WiFi after flashing
is done.
</p>
<h3>Customizing the look and feel</h3>
<p>
You can customize both the activation button and the message that is
shown when the user uses an unsupported browser. This can be done using
the <code>activate</code> and <code>unsupported</code> slots:
</p>
<pre>
&lt;esp-web-install-button
manifest="firmware_build/manifest.json"
erase-first
>
&lt;button slot="activate">Custom install button&lt;/button>
&lt;span slot="unsupported">Ah snap, your browser doesn't work!&lt;/span>
&lt;/esp-web-install-button>
