# Fluid – decentralized twitter-like feed built on Fluence with SQLite # Fluid – decentralized twitter-like feed built on Fluence with SQLite
## Workshop ## Workshop
### Step 0 – Framework Workshop scenario could be found [here](https://fluence.dev/page/workshop-fluid-decentralized-twitter-like-feed-built-on-fluence)
Here you can see the most basic Fluence app – just a hello-world.
Take a note of `#invocation_handler` macro, it marks function as an entry-point to your app. ## How to run steps
There's a `run.sh` script in each step, but if you'd like to run it manually, here's the instructions
```shell
### Step 1 – JSON API # Go into directory of the desired step (step3 used as example)
Now let's define some API for our feed backend. Let's use JSON as a communication format, and serde_json Rust library for handy serialization and deserialization. cd step3-finished-app
Two enums – `Request` and `Response` in [api.rs](step1-json-api/src/api.rs) describe API for interaction with frontend. # Download SQLite WASM module
mkdir wasm
wget https://github.com/fluencelabs/sqlite/releases/download/v0.2.0_w/sqlite3_0.2.0.wasm -O ./wasm/sqlite3_0.2.0.wasm
Method `parse` parses `Request` from JSON, and `serialize` converts `Response` back to JSON string, so it can be returned to frontend. # Build fluid WASM module
cargo +nightly build --target wasm32-unknown-unknown --release
cp target/wasm32-unknown-unknown/release/*.wasm ./wasm/
Here we also define [model.rs](step1-json-api/src/model.rs) – that's how we plan to use our database. Currently it is just a prototype, so we can implement our API in it's full. # Run it all on 30000 port with default Fluence API
docker run -it --rm -v $(pwd)/wasm:/code -p 30000:30000 fluencelabs/frun:latest
### Step 2 – Database ```
Let's forget for a moment about API, and dive into using SQLite module.
- [ffi.rs](step2-database-only/src/ffi.rs) describes inter-module communication between Fluid and SQLite
- [databse.rs](step2-database-only/src/database.rs) provides us with `query` function that executes SQL query on SQLite module, and returns result as a String
Now, take a look at [lib.rs](step2-database-only/src/lib.rs) – a few SQL requests are sent there.
First one creates the table for messages, next goes message insertion, emulating a user who's creating a post. Then, we select all messages and log them.
But we decided to use JSON as a communication format, and SQLite allows us to query results in json. So the last query does exactly that – it is the same as usual `SELECT *`, but wraps result in json array.
### Step 3 – Tying everything together
Now let's use our SQLite knowledge to implement [model.rs](step3-finished-app/src/model.rs) so our API can really persists and read data. And voilà, we have our backend for almost twitter, but it can be easily decentralized!
Also take a look at how to use frun [here](https://fluence.dev/docs/debugging) and look up HTTP API [here](https://fluence.dev/reference)
