Lamb 0.2

I've released Lamb 0.2, my micro blogging app that's powering this site.

What's new?

• Posts! Posts are statuses with a title. The title can be added in the front matter (front matter is parsed as an ini-string). Posts have a slug based on the title when the post was created.
• Individual statuses / posts have opengraph tags for improved sharing fidelity.
• The text editor grows to accommodate the input.

Basic routing using REQUEST_URI

So for nginx it is not straightforward to setup PHP-FPM so that PATH_INFO is correctly populated. Lamb uses the following /index.php/some/other type routing, where /some/other should be the PATH_INFO. Instead I want to make setup for a variety of web-servers straightforward, so I've switched to the more robust REQUEST_URI. This simplifies nginx configuration and Caddy and the PHP built-in web-server are compatible.

REQUEST_URI contains everything after the domain name, including the query string, so that needs to be removed:

$request_uri = '/home';
if ( $_SERVER['REQUEST_URI'] !== '/' ) {
    $request_uri = strtok( $_SERVER['REQUEST_URI'], '?' );
}

We can see that for a request for the root of the site, REQUEST_URI returns / whereas PATH_INFO would be empty, so the code above takes that into account. We can then deduct a router action as follows:

$action = strtok( $request_uri, '/' );

Once the $action is known, it can be checked against an allowed list of actions:

switch ( $action ) {
    case 'edit':
        ...
        break;
    default:
        respond_404();
        break;

404 Fallback comes to Lamb

I've added a 404 fallback feature to Lamb. What this means is that if you request a URL that doesn't exist on your Lamb instance, it will redirect to the same relative path on the domain you have provided in the configuration, if you enabled this feature.

This means you can move your site from example.com to say 2023.example.com and then set that as the 404 fallback url and you will not lose any SEO traffic! Here's an example! #lamb #projects

Alright got the webserver configuration figured out and the full site is up. Didn't forget about Caddy. #lamb #projects
