## Overview

Utility features to play with EIP-4844 blobs for Starknet usage.

## Usage

### As a CLI

You can use the CLI to recover the original data from a blob file and parse it into state diffs.

#### Install the CLI

```sh

cargo install majin-blob

```

#### Use the CLI

```sh

# Recover the original data from a blob file

majin-blob recover ./examples/blob/sn_blob_goerli.txt

```

#### Help

```sh

majin-blob --help

```

### As a library

Add the following to your `Cargo.toml`:

```toml

[dependencies]

majin-blob-core = "0.1.0"

majin-blob-types = "0.1.0"

```

Then you can use the library as follows:

```rust

use majin_blob_core::blob;

use majin_blob_types::serde;

fn main() {

    // Read the blob data from a file

    let blob_data = serde::parse_file_to_blob_data("./examples/blob/sn_blob_goerli.txt");

    // Recover the original data

    let original_data = blob::recover(blob_data);

    // Parse the original data into state diffs

    let state_diffs = serde::parse_state_diffs(original_data.as_slice());

    // Serialize the state diffs into JSON

    let state_diffs_json = serde::to_json(state_diffs.as_slice());

    println!("{}", state_diffs_json);

}

```

### Use the REST API

You can use the REST API to recover the original data from a blob file and parse it into state diffs.

#### Start the REST API

```sh

cargo run --release -p majin-blob-rest-api

```

#### Recover the original data from a blob file

```sh

curl -X POST --data-binary "@./examples/blob/sn_blob_goerli.txt" http://127.0.0.1:3030/blob

```
