FreshAPI

A FreshRSS / Google Reader API Plugin for Tiny-Tiny RSS

Background

Tiny-Tiny RSS is one of the best and most customizable self-hostable RSS readers available, but has limited compatibility with third party RSS readers through two APIs:

1. The Official API
2. The Fever API Plugin

Many mobile applications support one of these protocols, many do not. FreshAPI implements the FreshRSS / Google Reader API to allow Tiny-Tiny RSS to be used with more third party apps, and with more features.

Requirements

FreshAPI assumes that you're using the official docker based integration and running the latest version of TT-RSS. A change required for the API to work (enabling PATH_INFO for the plugins.local directory) was pushed on 9/11/2024, so any docker images from before that change will need to be updated.

If you are using another installation method you may need to make this PATH_INFO update yourself, more details here.

This plugin also uses backend components of the official auth_internal plugin, which is enabled by default with TT-RSS installs. If you've disabled this plugin you'll need to re-enable it to use freshapi.

Please provide details about your setup in any issues you open.

Installation

1. Clone this repository into your Tiny Tiny RSS plugins directory:

   cd tt-rss/plugins.local
   git clone https://github.com/eric-pierce/freshapi.git

2. Navigate to the Preferences menu in Tiny Tiny RSS, and check the box under "General" titled "Enable API"

   

3. In Preferences, open the Plugin menu and enable "freshapi"

   

4. When configuring your mobile app, select either "FreshRSS" or "Google Reader API". You'll need to point your client to your TT-RSS installation, depending on your setup. If you're using a subdomain to host TT-RSS then use https://yoursubdomain.yourdomain.com instead of https://yourdomain.com in the requests below.

   If you're using the standard docker installation use https://yourdomain.com/tt-rss/plugins.local/freshapi/api/greader.php as the server URL.

   If you're running the TT-RSS app at the website root (not including /tt-rss/ in the URL) by using the APP_WEB_ROOT and APP_BASE environment variables as described here you'll also need to remove tt-rss from the domain you use with clients: https://yourdomain.com/plugins.local/freshapi/api/greader.php

   Use your standard TT-RSS username and password. If you've enabled 2 Factor Authentication (2FA) generate and use an App Password.

Non-Official Docker based Installs

If you're using an install method other than the official docker images or Awesome-TTRSS then you may need to modify your nginx.conf files to support PATH_INFO, which is how the FreshRSS and Google Reader APIs pass requests to the backend server. This is as simple as adding a new "location" ruleset in the .conf file to enable PATH_INFO for the freshapi URL. You can use the nginx.conf files from the official and Awesome-TTRSS installs as a guide, and there's a discussion about enabling this here.

NixOS

If you're using NixOS with Postgres, use the following as a template:

configuration.nix

   services.tt-rss = {
     enable = true;
     database = {
       type = "pgsql";
     };
     selfUrlPath = "http://<Host>";
     virtualHost = "<Host>";
     pluginPackages = [ (pkgs.callPackage ./freshapi.nix {}) ];
   };

PATH_INFO nginx config in configuration.nix

     virtualHosts."<HOST from above>" = {
       locations."~ /plugins\\.local/.*/api/.*\\.php(/|$)" = {
         extraConfig = ''
           fastcgi_split_path_info ^(.+\.php)(/.+)$;
           try_files $fastcgi_script_name =404;
           set $path_info $fastcgi_path_info;
           fastcgi_param PATH_INFO $path_info;
           fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
           fastcgi_pass unix:/run/phpfpm/tt-rss.sock;
           include ${config.services.nginx.package}/conf/fastcgi_params;
           fastcgi_index index.php;
         '';
       };

freshapi.nix should contain:

{ lib, stdenv, fetchFromGitHub, tt-rss }:

stdenv.mkDerivation {
  pname = "tt-rss-plugin-freshapi";
  version = "0.01";

  src = fetchFromGitHub {
    owner = "eric-pierce";
    repo = "freshapi";
    rev = "942b1c37ef2035444c3a22a21e225f3ece73c705"; # this and the line below needs to be updated based on the git sha of freshapi you want to install
    sha256 = "sha256-XWzEya+1A/UtwTL+HseoX8trEypNjHurK/VF3k2seMQ";
  };

  installPhase = ''
    mkdir -p $out/freshapi
    cp -r api init.php $out/freshapi
  '';

  meta = with lib; {
    description = "Tiny Tiny RSS FreshAPI Plugin";
    longDescription = ''
      A FreshRSS / Google Reader API Plugin for Tiny-Tiny RSS
    '';
    license = with licenses; [ agpl3Only ];
    homepage = "https://github.com/eric-pierce/freshapi";
    maintainers = with maintainers; [ bigloser ];
    inherit (tt-rss.meta) platforms;
  };
}

Compatible Clients

The following clients have been tested, but FreshAPI should be compatible with any FreshRSS or Google Reader API compatible client. If you run into any issues or would like to report a client as working, please open up an issue.

Direct API Usage

FreshRSS and Google Reader compatible clients can natively use this API, but if you'd like to access it directly you can do so by making cURL calls. The Google Reader API spec is well documented, but here is an example of API usage:

1. Authorization

Make a POST cURL call to your server's ClientLogin Endpoint using your TT-RSS username and password. If you have enabled 2FA you can use an App password generated in the TT-RSS preferences pane

foo@bar:~$ curl -X POST --data 'Email=yourusername&Passwd=yourpassword' https://example.com/tt-rss/plugins.local/freshapi/api/greader.php/accounts/ClientLogin/

This will return your authorization credentials in the format 'username/session_id"

SID=yourusername/r4ih6gt412opqh11gptp3hodd6
LSID=
Auth=yourusername/r4ih6gt412opqh11gptp3hodd6

2. Calling the API Directly

Take the username/session_id combination from step 1 and make a new cURL call to the endpoint you'd like to use. In this case we'll ask to export the subscription, folder, and tag OPML through the subscription export feature:

foo@bar:~$ curl -X POST --header 'Authorization: GoogleLogin auth=yourusername/r4ih6gt412opqh11gptp3hodd6' https://example.com/tt-rss/plugins.local/freshapi/api/greader.php/reader/api/0/subscription/export

In the example above the cURL call will return your subscription OPML in XML form.

Updates

FreshAPI uses a rolling release approach, though I'll increment the version number for significant changes. If cloned into the plugins.local folder TT-RSS should keep the plugin up to date.
