Gcore FastEdge

1. Create a new FastEdge app

Initialize a Rust project with the FastEdge SDK:

mkdir myapp && cd myapp

Create .cargo/config.toml:

[build]
target = "wasm32-wasip1"

Create Cargo.toml:

[package]
name = "myapp"
version = "0.1.0"
edition = "2021"
[lib]
crate-type = ["cdylib"]
[dependencies]
fastedge = "0.2"

Create src/lib.rs:

use fastedge::{
    body::Body,
    http::{Request, Response, StatusCode, Error},
};
#[fastedge::http]
fn main(_req: Request) -> Result, Error> {
    Response::builder()
        .status(StatusCode::OK)
        .header("content-type", "text/plain")
        .body(Body::from("Hello from FastEdge!"))
}

2. Build the Wasm binary

Requires Rust and wasm32-wasip1 target:

rustup target add wasm32-wasip1
cargo build --release

Binary location: target/wasm32-wasip1/release/myapp.wasm

3. Deploy via CLI

Set your API key (get from https://accounts.gcore.com/account-settings/api-tokens):

export GCORE_API_KEY="your_api_token"

Upload binary:

curl -X POST \
  'https://api.gcore.com/fastedge/v1/binaries/raw' \
  -H 'accept: application/json' \
  -H "Authorization: APIKey $GCORE_API_KEY" \
  -H 'Content-Type: application/octet-stream' \
  --data-binary '@./target/wasm32-wasip1/release/myapp.wasm'

Save the id from response (binary_id).

Create app:

curl -X POST \
  'https://api.gcore.com/fastedge/v1/apps' \
  -H 'accept: application/json' \
  -H 'client_id: 0' \
  -H "Authorization: APIKey $GCORE_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{
    "name": "my-app-name",
    "binary": BINARY_ID,
    "status": 1
  }'

Your app will be at: https://my-app-name-XXXX.fastedge.app
