Non-static method Statamic\StaticSite\Generator::after() should not be called statically

Statamic Static Site Generator

Generate static sites with Statamic.

Installation

You can install the Static Site Generator package with the following command:

php please install:ssg

The command will install the statamic/ssg package via Composer, optionally publish the configuration file and prompt you if you wish to install the spatie/fork package for running multiple workers.

Usage

Run the following command:

php please ssg:generate

Your site will be generated into a directory which you can deploy however you like. See Deployment Examples below for inspiration.

Multiple Workers

For improved performance, you may spread the page generation across multiple workers. This requires Spatie's Fork package. Then you may specify how many workers are to be used. You can use as many workers as you have CPU cores.

composer require spatie/fork
php please ssg:generate --workers=4

Routes

Routes will not automatically be generated. You can add any additional URLs you wish to be generated by adding them to the urls array in the config file.

'urls' => [
    '/this-route',
    '/that-route',
],

You can also exclude single routes, or route groups with wildcards. This will override anything in the urls config.

'exclude' => [
    '/secret-page',
    '/cheat-codes/*',
],

Dynamic Routes

You may add URLs dynamically by providing a closure that returns an array to the addUrls method.

use Statamic\StaticSite\SSG;

class AppServiceProvider extends Provider
{
    public function boot()
    {
        SSG::addUrls(function () {
            return ['/one', '/two'];
        });
    }
}

Pagination Routes

Wherever pagination is detected in your antlers templates (eg. if you use the paginate param on the collection tag), multiple pages will automatically be generated with /articles/page/2 style urls.

You may configure a custom routing style in config/statamic/ssg.php:

'pagination_route' => '{url}/{page_name}/{page_number}',

Post-generation callback

You may optionally define extra steps to be executed after the site has been generated.

use Statamic\StaticSite\SSG;

class AppServiceProvider extends Provider
{
    public function boot()
    {
        SSG::after(function () {
            // eg. copy directory to some server
        });
    }
}

Glide Images

The default configuration of Statamic is to have Glide use "dynamic" images, which means that the glide tag will only output URLs. The images themselves will be generated when the URLs are visited. For a static site, this no longer makes sense since it will typically be deployed somewhere where there is no dynamic Glide route available.

By default, the SSG will automatically reconfigure Glide to generate images into the img directory whenever glide tags are used. This is essentially Glide's custom static path option.

You can customize where the images will be generated:

'glide' => [
    'directory' => 'images',
],

If you are using a custom glide disk, you can tell the SSG to leave it alone:

'glide' => [
    'override' => false,
],

And then copy the images over (or create a symlink) after generating has completed:

SSG::after(function () {
    $from = public_path('img');
    $to = config('statamic.ssg.destination').'/img';

    app('files')->copyDirectory($from, $to);
    // or
    app('files')->link($from, $to);
});

Triggering Command Failures

If you are using the SSG in a CI environment, you may want to prevent the command from succeeding if any pages aren't generated (e.g. to prevent deployment of an incomplete site).

By default, the command will finish and exit with a success code even if there were un-generated pages. You can tell configure the SSG to fail early on errors, or even on warnings.

'failures' => 'errors', // or 'warnings'

Deployment Examples

These examples assume your workflow will be to author content locally and not using the control panel in production.

Deploy to Netlify

Deployments are triggered by committing to Git and pushing to GitHub.

Create a site in your Netlify account
Link the site to your desired GitHub repository
Add build command php please ssg:generate (if you need to compile css/js, be sure to add that command too and execute it before generating the static site folder. e.g. npm install && npm run build && php please ssg:generate).
Set publish directory storage/app/static

After your site has an APP_URL...

Set it as an environment variable. Add APP_URL https://thats-numberwang-47392.netlify.com

Finally, generate an APP_KEY to your .env file locally using php artisan key:generate and copy it's value, then...

Set it as an environment variable. Add APP_KEY [your app key value]

S3 Asset Containers

If you are storing your assets in an S3 bucket, the .envs used will need to be different to the defaults that come with Laravel, as they are reserved by Netlify. For example, you can amend them to the following:

# .env
AWS_S3_ACCESS_KEY_ID=
AWS_S3_SECRET_ACCESS_KEY=
AWS_S3_DEFAULT_REGION=
AWS_S3_BUCKET=
AWS_URL=

Be sure to also update these in your s3 disk configuration:

// config/filesystems.php
's3' => [
    'driver' => 's3',
    'key' => env('AWS_S3_ACCESS_KEY_ID'),
    'secret' => env('AWS_S3_SECRET_ACCESS_KEY'),
    'region' => env('AWS_S3_DEFAULT_REGION'),
    'bucket' => env('AWS_S3_BUCKET'),
    'url' => env('AWS_URL'),
],

Deploy to Vercel

Deployments are triggered by committing to Git and pushing to GitHub.

Create a new file called ./build.sh and paste the code snippet below.
Run chmod +x build.sh on your terminal to make sure the file can be executed when deploying.
Import a new site in your Vercel account
Link the site to your desired GitHub repository
Add build command ./build.sh
Set output directory to storage/app/static
Add environment variable in your project settings: APP_KEY <copy & paste from dev>

Code for build.sh

Add the following snippet to build.sh file to install PHP, Composer, and run the ssg:generate command:

#!/bin/sh

# Install PHP & WGET
yum install -y amazon-linux-extras
amazon-linux-extras enable php7.4
yum clean metadata
yum install php php-{common,curl,mbstring,gd,gettext,bcmath,json,xml,fpm,intl,zip,imap}
yum install wget

# INSTALL COMPOSER
EXPECTED_CHECKSUM="$(wget -q -O - https://composer.github.io/installer.sig)"
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
ACTUAL_CHECKSUM="$(php -r "echo hash_file('sha384', 'composer-setup.php');")"

if [ "$EXPECTED_CHECKSUM" != "$ACTUAL_CHECKSUM" ]
then
    >&2 echo 'ERROR: Invalid installer checksum'
    rm composer-setup.php
    exit 1
fi

php composer-setup.php --quiet
rm composer-setup.php

# INSTALL COMPOSER DEPENDENCIES
php composer.phar install

# GENERATE APP KEY
php artisan key:generate

# BUILD STATIC SITE
php please ssg:generate

Deploy to Surge

Prerequisite: Install with npm install --global surge. Your first deployment will involve creating an account via command line.

Build with command php please ssg:generate
Deploy with surge storage/app/static

Deploy to Firebase hosting

Prerequisite: Follow the instructions to get started with Firebase hosting

Once hosting is set up, make sure the public config in your firebase.json is set to storage/app/static
(Optionally) Add a predeploy config to run php please ssg:generate
Run firebase deploy
