+
+Solar Network is a social network developed by Solsynth LLC, aiming to become the next-generation social network.
+
+## Tech Stack
+
+The Solar Network project follows the classic frontend-backend separation architecture, with the entire project divided into two parts: the frontend (Solian) and the backend (Hydrogen.Dealer, Hydrogen.Passport, etc.).
+
+### Frontend
+
+The frontend of Solar Network is a cross-platform client built with Flutter. For more details, check the [related page](solar-network/solian).
+
+### Backend
+
+The backend of Solar Network follows what we define as a "mid-service" architecture. Compared to microservices, each individual service is responsible for more tasks and is larger in scope, allowing us to maintain multiple projects more easily. At the same time, issues with a single service won't cause an overall outage.
+
+At the center of it all is our core service — Hydrogen.Dealer, which serves as both the service discovery system and mid-service gateway. It is also the only external interface for Solar Network, with `api.sn.solsynth.dev` being the gateway exposed by Hydrogen.Dealer.

+title: Stickers and Sticker Packs
+description: Stickers, Emotes, and Emojis
+---
+
+Stickers help users express their emotions better on Solar Network. This article introduces how to upload and use a sticker.
+
+## Sticker Packs
+
+Stickers must be part of a sticker pack. To create a sticker pack, go to the "Creator Hub" > "Stickers" section on the website sidebar.
+
+## Stickers
+
+Before creating a sticker, you’ll need to prepare the content. It is recommended to use a PNG or GIF image that is 1024x1024 pixels (minimum 128x128). The background can be transparent or not, but avoid solid color fills. Large white fills may cause discomfort for users in dark mode, akin to a flashbang.
+
+Once the sticker pack is created, open it and select the plus symbol under "Actions" to add a sticker.
+
+You might need to upload an attachment for the sticker material. After uploading, fill in the "Attachment" field with the Random ID (the series of characters after the #) from the completed upload. If the content displays correctly, the connection is successful.
+
+After that, simply fill out the form to finish.
+
+## Usage
+
+To use a sticker, type a placeholder in your content, formatted as `:<pack prefix><sticker alias>:`.
+For example, if a sticker pack has the prefix `solar` and a sticker alias `Hello`, the resulting placeholder would be `:solarHello:`.
+
+Don’t worry if that seems confusing—most of the time, we provide automatic suggestions. Simply type a colon in the Solian text box, followed by part of the placeholder, and suggestions will appear.
+
+### Size Variations
+
+In Solar Network, you may notice stickers appear in different sizes due to Smart Resize. The rules are as follows:
+
+1. If only one sticker is present, it will appear at 128x128.
+2. If three or fewer stickers are present, they will appear at 32x32.
+3. If more than three stickers are present, or if stickers are embedded within text, they will appear at 20x20.
+
+These adjustments are applied within a single paragraph.

+title: API Standards
+description: The guidelines we follow when designing Solar Network service APIs
+---
+
+This article covers the paradigms we follow when designing Solar Network APIs, helping you better interact with our APIs for secondary development.
+
+## Minimization
+
+Our APIs aim to be minimalistic. Unlike some major platforms, where the response includes not only data but also a bunch of status codes, messages, and request IDs, we keep such information in the HTTP headers. The HTTP response body contains only the raw data, with no extra information (for paginated endpoints, an additional field for total count will be included).
+
+## CRUD Operations
+
+Our APIs generally follow RESTful design patterns. If you're unfamiliar with RESTful principles, here’s how we practice it:
+
+### Request Methods
+
+- `GET` for fetching data
+- `POST` for creating or performing some operations
+- `PUT` for updating (though in RESTful principles it's also defined for creation, we don’t use it that way)
+- `PATCH` for updating (rarely used)
+- `DELETE` for removing data
+
+### Path Mapping
+
+If you use `POST` to create data at an endpoint, using `GET` on the same endpoint will typically list the data.
+Appending `/<id>` to the path will fetch a specific data entry. Switching the request method to `PUT` updates the entry, and using `DELETE` removes it.
+If additional actions are needed, append paths after `/<id>`, usually for operations handled via `POST`.
+
+Here’s an example of path mapping for posts:
+
+*Note: `:id` is a path parameter.*
+
+- `GET /posts` - Retrieves a list of posts (paginated)
+- `GET /posts/:id` - Retrieves a specific post
+- `GET /posts/:id/replies` - Retrieves replies for a specific post (paginated)
+- `POST /posts` - ~~Creates a post~~ (removed in the new version due to post types; use the specific post type creation endpoint)
+- `PUT /posts/:id` - ~~Updates a post~~ (removed in the new version due to post types; use the specific post type update endpoint)
+- `DELETE /posts/:id` - Deletes a post
+- `POST /posts/:id/pin` - Pins a post
+- `POST /posts/:id/react` - Reacts to a post
+
+## Error Handling
+
+We don’t understand why, despite HTTP providing a complete set of status codes, other large companies still create their own. For HTTP status codes, here’s a summary of common meanings:
+
+- `500` - Internal Server Error — No need to worry; just file an issue if it happens frequently.
+- `400` - Bad Request — Check the documentation and request body.
+- `404` - Data not found or incorrect API path.
+- `403` - Forbidden — You don’t have permission.
+- `401` - Unauthorized — API token required but not provided.
+- `200` - Success
+- `204` - No Content — Common for delete operations (though often forgotten during API development).
+
+If the response status is not `2xx`, we usually return a `plain/text` response instead of `application/json`, providing a simple line of text indicating the error.
+
+> If you’re not good at English, don’t keep asking us about errors — use a translator! Why else would we write error messages?
+
+## Super Gateway
+
+The Super Gateway refers to our [Hydrogen.Dealer](https://git.solsynth.dev/Hydrogen/Dealer). In most cases, you won’t directly access our services; requests are forwarded through the Dealer gateway. We’re not even sure why we created this.
+
+Our API base URL is `api.sn.solsynth.dev`. How do you use it? It’s simple. Access `/cgi/<service name>`, and this path will be forwarded to the corresponding service’s `/api` endpoint. In the latest version, we also introduced aliases for these services, making the URLs more readable.
+
+- `/cgi/id` or `/cgi/auth` — Authentication service [Hydrogen.Passport](https://git.solsynth.dev/Hydrogen/Passport)
+- `/cgi/uc` or `/cgi/files` — Attachment service [Hydrogen.Paperclip](https://git.solsynth.dev/Hydrogen/Paperclip)
+- `/cgi/co` or `/cgi/interactive` — Post service [Hydrogen.Interactive](https://git.solsynth.dev/Hydrogen/Interactive)
+- `/cgi/im` or `/cgi/messaging` — Messaging service [Hydrogen.Messaging](https://git.solsynth.dev/Hydrogen/Messaging)
+
+> Fun fact: You might have noticed that the new aliases are actually the subdomains used before we had the Super Gateway.

+title: Solian Chain
+description: Solian is the official cross-platform client developed by Solsynth LLC.
+---
+
+Solian is the cross-platform Solar Network client built with Flutter, and currently, it’s our only frontend.
+
+# Usage
+
+To use Solian, you can either download the client or open it directly in your browser. Thanks to Flutter’s cross-platform support, you can access the web version of Solian at https://lian.solsynth.dev. However, due to browser limitations, some features may be missing or affected.
+
+## Download
+
+There are many ways to download Solsynth, but make sure to download from officially certified channels.
+
+1. The official release version from the repository: https://git.solsynth.dev/Hydrogen/Solian/releases
+2. The test version from the official file storage: https://files.solsynth.dev/production01/solian
+3. Official TestFlight (iOS and some macOS): https://testflight.apple.com/join/YJ0lmN6O
+
+The Windows version is a portable version. You can place it in a directory you're familiar with and run it directly.
+The web version also supports PWA (Progressive Web Application), which can replace some desktop usage.
+
+## Installation
+
+Below are the technical instructions for installing Solian on different platforms.
+
+### Android
+
+It is recommended to download the latest test version from the **file storage**. It has the latest fixes and is the most stable. ~~The test version is more stable than the stable version.~~
+
+You can open and install the downloaded APK file directly. For Chinese phones, additional steps may be required for verification, but please avoid searching for and downloading from built-in app stores.
+
+### iOS/macOS
+
+Use TestFlight for installation. First, click the link above to download the TestFlight app. Then, click "Start Testing" in the second step of the link to join the test.
+
+TestFlight has a limited number of testing slots. Once the time is right, we will release Solian on the App Store (non-China region), where you can search and download it.
+
+### Windows
+
+After downloading from any trusted source, extract it to a directory, and you can start using it.
+
+**Note:** It seems that, due to a potential Flutter support issue, the Windows version often freezes for a while during the first startup before displaying the main window. Please be patient and avoid clicking repeatedly, as it may take 5 to 30 seconds. Repeated clicking may open multiple windows.
+
+### Linux
+
+Please build it yourself. I believe you can do it — good luck!
+
+## Build It Yourself
+
+### Preparing the Environment
+
+Building Solian requires the Flutter SDK. Please download the latest version from the official site. Alternatively, you can download it from a China mirror.
+After installing Flutter, follow the official documentation to install other platform-specific dependencies (e.g., Windows requires VS2022, Android requires Android Studio, and for iOS/macOS, it’s better to use the official pre-built version).
+
+In addition to installing the Flutter SDK, we need Rust for system-level dependencies. Please download the latest version from the official Rust site.
+
+Now that we have Flutter and Rust, we need one more thing — SQLite3, to support local databases for chat and future modules.
+For Linux, you need to install the corresponding SQLite3 development dependencies:
+
+```sh
+# for ubuntu
+sudo apt-get -y install libsqlite3-0 libsqlite3-dev
+```
+
+For Windows, download the
+[sqlite3.dll](https://github.com/tekartik/sqflite/raw/master/sqflite_common_ffi/lib/src/windows/sqlite3.dll)
+and place it in the running directory.
+No additional steps are needed for macOS or mobile builds.
+
+### Building the Code
+
+Next, it’s time to build the code. Ensure that you have `git` installed on your build machine. Alternatively, you can download the code as a compressed archive.
+Once `git` is installed, use the following command to clone the code:
+
+```sh
+git clone https://git.solsynth.dev/Hydrogen/Solian.git
+```
+
+Navigate to the corresponding directory and install dependencies using the following command:
+
+```sh
+flutter pub get
+```
+
+This will download dependencies from [pub.dev](https://pub.dev), hosted by Google. Connectivity within mainland China might be questionable. Refer to mirror sites for solutions.
+
+Once the dependencies are installed, you can proceed with the build. Just one line of code:
+
+```sh
+# for windows
+flutter build windows
+# for macos
+flutter build macos
+# for linux
+flutter build linux
+# for ios
+flutter build ipa
+# for android
+flutter build apk
+```
+
+You can also build other formats for Android, such as `aab`, but please prepare the necessary signing materials yourself.
