Overview
A Laravel package that can be used for fetching favicons from websites.
Installation
Requirements
The package has been developed and tested to work with the following minimum requirements:
- PHP 8.0
- Laravel 8.0
Install the Package
You can install the package via Composer:
composer require ashallendesign/favicon-fetcher
Publish the Config
You can then publish the package's config file by using the following command:
php artisan vendor:publish --provider="AshAllenDesign\FaviconFetcher\FaviconFetcherProvider"
Usage
Fetching Favicons
Now that you have the package installed, you can start fetching the favicons from different websites.
Using the fetch
Method
To fetch a favicon from a website, you can use the fetch
method which will return an instance of AshAllenDesign\FaviconFetcher\Favicon
:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$favicon = Favicon::fetch('https://ashallendesign.co.uk');
Using the fetchOr
Method
If you'd like to provide a default value to be used if a favicon cannot be found, you can use the fetchOr
method.
For example, if you wanted to use a default icon (https://example.com/favicon.ico
) if a favicon could not be found, your code could look something like this:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$favicon = Favicon::fetchOr('https://ashallendesign.co.uk', 'https://example.com/favicon.ico');
This method also accepts a Closure
as the second argument if you'd prefer to run some custom logic. The url
field passed as the first argument to the fetchOr
method is available to use in the closure. For example, to use a closure, your code could look something like this:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$favicon = Favicon::fetchOr('https://ashallendesign.co.uk', function ($url) {
// Run extra logic here...
return 'https://example.com/favicon.ico';
});
Using the fetchAll
Method
There may be times when you want to retrieve the different sized favicons for a given website. To get the different sized favicons, you can use the fetchAll
method which will return an instance of AshAllenDesign\FaviconFetcher\Collections\FaviconCollection
. This collection contains instances of AshAllenDesign\FaviconFetcher\Favicon
. For example, to get all the favicons for a site, you can use the fetchAll
method like so:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$favicons = Favicon::fetchAll('https://ashallendesign.co.uk');
The FaviconCollection
class extends the Illuminate\Support\Collection
class, so you can use all the methods available on the Collection
class.
It also includes a largest
method that you can use to get the favicon with the largest dimensions. It's worth noting that if the size of the favicon is unknown, it will be treated as if it has a size of 0x0px
when determining which is the largest. For example, you can use the largest
method like this:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$largestFavicon = Favicon::fetchAll('https://ashallendesign.co.uk')->largest();
The FaviconCollection
also provides a largestByFileSize
method that you can use to get the favicon with the largest file size. You may want to do this if the package cannot detect the sizes of the icons for a given website, and so it can't detect the largest icon. This method works based on the assumption that the larger the file size, the larger the image dimensions. For example, you can use the largestByFileSize
method like this:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$largestFavicon = Favicon::fetchAll('https://ashallendesign.co.uk')->largestByFileSize();
Note: Only the http
driver supports retrieving all the favicons for a given website. For this reason, the fetchAll
method does not support fallbacks. Support may be added for other drivers and fallbacks in the future.
Using the fetchAllOr
Method
If you'd like to provide a default value to be used if all the favicons for a site cannot be found, you can use the fetchAllOr
method.
For example, if you wanted to use a default icon (https://example.com/favicon.ico
) if the favicons could not be found, your code could look something like this:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$favicon = Favicon::fetchAllOr('https://ashallendesign.co.uk', 'https://example.com/favicon.ico');
This method also accepts a Closure
as the second argument if you'd prefer to run some custom logic. The url
field passed as the first argument to the fetchAllOr
method is available to use in the closure. For example, to use a closure, your code could look something like this:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$favicon = Favicon::fetchAllOr('https://ashallendesign.co.uk', function ($url) {
// Run extra logic here...
return 'https://example.com/favicon.ico';
});
Exceptions
By default, if a favicon can't be found for a URL, the fetch
method will return null
. However, if you'd prefer an exception to be thrown, you can use the throw
method available on the Favicon
facade. This means that if a favicon can't be found, an AshAllenDesign\FaviconFetcher\Exceptions\FaviconNotFoundException
will be thrown.
To enable exceptions to be thrown, your code could look something like this:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$favicon = Favicon::throw()->fetch('https://ashallendesign.co.uk');
If you attempt to fetch a favicon and the request times out or no website is found at the URL, an AshAllenDesign\FaviconFetcher\Exceptions\ConnectionException
will be thrown. This will be thrown even if the throw
method has not been used.
Drivers
Favicon Fetcher provides the functionality to use different drivers for retrieving favicons from websites.
Available Drivers
By default, Favicon Fetcher ships with 5 drivers out-the-box: http
, google-shared-stuff
, favicon-kit
, unavatar
, favicon-grabber
.
The http
driver fetches favicons by attempting to parse "icon" and "shortcut icon" link elements from the returned HTML of a webpage. If it can't find one, it will attempt to guess the URL of the favicon based on common defaults.
The google-shared-stuff
driver fetches favicons using the Google Shared Stuff API.
The favicon-kit
driver fetches favicons using the Favicon Kit API.
The unavatar
driver fetches favicons using the Unavatar API.
The favicon-grabber
driver fetches favicons using the Favicon Grabber API.
How to Choose a Driver
It's important to remember that the google-shared-stuff
, favicon-kit
, and unavatar
drivers interact with third-party APIs to retrieve the favicons. So, this means that some data will be shared to external services.
However, the http
driver does not use any external services and directly queries the website that you are trying to fetch the favicon for. Due to the fact that this package is new, it is likely that the http
driver may not be 100% accurate when trying to fetch favicons from websites. So, theoretically, the http
driver should provide you with better privacy, but may not be as accurate as the other drivers.
Choosing a Driver
You can select which driver to use by default by changing the default
field in the favicon-fetcher
config file after you've published it. The package originally ships with the http
driver enabled as the default driver.
For example, if you wanted to change your default driver to favicon-kit
, you could update your favicon-fetcher
config like so:
return [
// ...
'default' => 'favicon-kit',
// ...
]
If you'd like to set the driver on-the-fly, you can do so by using the driver
method on the Favicon
facade. For example, if you wanted to use the google-shared-stuff
driver, you could do so like this:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$favicon = Favicon::driver('google-shared-stuff')->fetch('https://ashallendesign.co.uk');
Fallback Drivers
There may be times when a particular driver cannot find a favicon for a website. If this happens, you can fall back and attempt to find it again using a different driver.
For example, if we wanted to try and fetch the favicon using the http
driver and then fall back to the google-shared-stuff
driver if we can't find it, your code could look something like this:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$favicon = Favicon::withFallback('google-shared-stuff')->fetch('https://ashallendesign.co.uk');
Adding Your Own Driver
There might be times when you want to provide your own custom logic for fetching favicons. To do this, you can build your driver and register it with the package for using.
First, you'll need to create your own class and make sure that it implements the AshAllenDesign\FaviconFetcher\Contracts\Fetcher
interface. For example, your class could like this:
use AshAllenDesign\FaviconFetcher\Contracts\Fetcher;
use AshAllenDesign\FaviconFetcher\Favicon;
class MyCustomDriver implements Fetcher
{
public function fetch(string $url): ?Favicon
{
// Add logic here that attempts to fetch a favicon...
}
public function fetchOr(string $url, mixed $default): mixed
{
// Add logic here that attempts to fetch a favicon or return a default...
}
}
After you've created your new driver, you'll be able to register it with the package using the extend
method available through the Favicon
facade. You may want to do this in a service provider so that it is set up and available in the rest of your application.
You can register your custom driver like so:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
Favicon::extend('my-custom-driver', new MyCustomDriver());
Now that you've registered your custom driver, you'll be able to use it for fetching favicons like so:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$favicon = Favicon::driver('my-custom-driver')->fetch('https://ashallendesign.co.uk');
HTTP Timeouts
Favicon Fetcher provides the ability for you to set the connection timeout and request timeout for all the drivers.
The connection timeout is the time that the package will wait for a connection to be made to the website. The request timeout is the time that the package will wait for the website to respond to the request.
To do this, you can update the connect_timeout
and timeout
fields in the favicon-fetcher.php
config file after you've published it. For example, to set the connection timeout to 5 seconds and the request timeout to 10 seconds, you could update your config file like so:
return [
// ...
'connect_timeout' => 5,
'timeout' => 10,
// ...
]
If you'd prefer that no timeout be set, you can set the values to 0
.
Please note that these timeouts are applied to all HTTP requests that Favicon Fetcher makes, regardless of the driver that is being used.
TLS Verification
Favicon Fetcher uses TLS verification by default, but this can be disabled. This can be useful in development environments or situations where you might be working with self-signed certificates or certificates from an untrusted certificate authority.
You can disable the verification by updating the verify_tls
field in the favicon-fetcher.php
config file after you've published it.
return [
// ...
'verify_tls' => false,
// ...
]
Or by updating your .env
file:
FAVICON_FETCHER_VERIFY_TLS=false
HTTP User Agent
You may find that your requests are sometimes blocked by websites when trying to retrieve a favicon. This may be due to the fact that the default Guzzle User-Agent
header is passed in the requests.
Favicon Fetcher allows you to set the User-Agent
header that is used in the package's requests. To do this, you can update the user_agent
field in the favicon-fetcher.php
config file after you've published it. For example, to set the User-Agent
header to My Custom User Agent
, you could update your config file like so:
return [
// ...
'user_agent' => 'My Custom User Agent',
// ...
]
The User-Agent
header will be set on all HTTP requests that Favicon Fetcher makes, regardless of the driver that is being used.
The user_agent
config field is already configured in the config file to read directly from a FAVICON_FETCHER_USER_AGENT
field in your .env
file. So, if you'd prefer to set the User-Agent
header in your .env
file, you could do so like this:
FAVICON_FETCHER_USER_AGENT="My Custom User Agent"
Storing Favicons
After fetching favicons, you might want to store them in your filesystem so that you don't need to fetch them again in the future. Favicon Fetcher provides two methods that you can use for storing the favicons: store
and storeAs
.
Using store
If you use the store
method, a filename will automatically be generated for the favicon before storing. The method's first parameter accepts a string and is the directory that the favicon will be stored in. You can store a favicon using your default filesystem disk like so:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$faviconPath = Favicon::fetch('https://ashallendesign.co.uk')->store('favicons');
// $faviconPath is now equal to: "/favicons/abc-123.ico"
If you'd like to use a different storage disk, you can pass it as an optional second argument to the store
method. For example, to store the favicon on S3, your code use the following:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$faviconPath = Favicon::fetch('https://ashallendesign.co.uk')->store('favicons', 's3');
// $faviconPath is now equal to: "/favicons/abc-123.ico"
Using storeAs
If you use the storeAs
method, you will be able to define the filename that the file will be stored as. The method's first parameter accepts a string and is the directory that the favicon will be stored in. The second parameter specifies the favicon filename (excluding the file extension). You can store a favicon using your default filesystem disk like so:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$faviconPath = Favicon::fetch('https://ashallendesign.co.uk')->storeAs('favicons', 'ashallendesign');
// $faviconPath is now equal to: "/favicons/ashallendesign.ico"
If you'd like to use a different storage disk, you can pass it as an optional third argument to the storeAs
method. For example, to store the favicon on S3, your code use the following:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$faviconPath = Favicon::fetch('https://ashallendesign.co.uk')->storeAs('favicons', 'ashallendesign', 's3');
// $faviconPath is now equal to: "/favicons/ashallendesign.ico"
Caching Favicons
As well as being able to store favicons, the package also allows you to cache the favicon URLs. This can be extremely useful if you don't want to store a local copy of the file and want to use the external version of the favicon that the website uses.
As a basic example, if you have a page displaying 50 websites and their favicons, we would need to find the favicon's URL on each page load. As can imagine, this would drastically increase the page load time. So, by retrieving the URLs from the cache, it would majorly improve up the page speed.
To cache a favicon, you can use the cache
method available on the Favicon
class. The first parameter accepts a Carbon\CarbonInterface
as the cache lifetime. For example, to cache the favicon URL of https://ashallendesign.co.uk
for 1 day, your code might look something like:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$favicon = Favicon::fetch('https://ashallendesign.co.uk')->cache(now()->addDay());
By default, the package will always try and resolve the favicon from the cache before attempting to retrieve a fresh version. However, if you want to disable the cache and always retrieve a fresh version, you can use the useCache
method like so:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$favicon = Favicon::useCache(false)->fetch('https://ashallendesign.co.uk');
The package uses favicon-fetcher
as a prefix for all the cache keys. If you'd like to change this, you can do so by changing the cache.prefix
field in the favicon-fethcher
config file. For example, to change the prefix to my-awesome-prefix
, you could update your config file like so:
return [
// ...
'cache' => [
'prefix' => 'my-awesome-prefix',
]
// ...
]
The package also provides the functionality for you to cache collections of favicons that have been retrieved using the fetchAll
method. You can do this by calling the cache
method on the FaviconCollection
class like so:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$faviconCollection = Favicon::fetchAll('https://ashallendesign.co.uk')->cache(now()->addDay());
Favicon Types
When attempting to retrieve favicons using the http
driver, we may be able to determine the favicons' type (such as icon
, shortcut icon
, or apple-touch-icon
). To get the type of the favicon, you can use the getIconType
method like so:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$faviconPath = Favicon::fetch('https://ashallendesign.co.uk')->getIconType();
This method can return one of four constants defined on the Favicon
class: TYPE_ICON
, TYPE_SHORTCUT_ICON
, TYPE_APPLE_TOUCH_ICON
, and TYPE_ICON_UNKNOWN
.
You can make use of these constants for things like filtering. For example, if you wanted to get all the icons except the apple-touch-icon
, you could do the following:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$faviconCollection = Favicon::fetchAll('https://ashallendesign.co.uk');
$faviconCollection->filter(function ($favicon) {
return $favicon->getIconType() !== Favicon::TYPE_APPLE_TOUCH_ICON;
});
Favicon Sizes
When attempting to retrieve favicons using the http
driver, we may be able to determine the favicons' sizes. To get the size of the favicon, you can use the getIconSize
method like so:
use AshAllenDesign\FaviconFetcher\Facades\Favicon;
$faviconSize = Favicon::fetch('https://ashallendesign.co.uk')->getIconSize();
It's assumed that the icons are square, so only a single integer will be returned. For example, if a favicon is 16x16px, then the getIconSize
method will return 16
. If the size is unknown, null
will be returned.
