@ tcute/ car( 车)

aT 协议的可处理档案(CAR)编码器.

npm install @atcute/car

此库执行 DASL 的 中非共和国 aT 协议用于存储和转让的格式 仓库数据.

使用量

流式使用量

import { fromStream } from '@atcute/car';

const stream = new ReadableStream({/* ... */});

await using car = fromStream(stream);

const roots = await car.roots();

for await (const entry of car) {
    entry;
    // ^? CarEntry { cid: CidLink {}, bytes: Uint8Array {}, ... }
}

流媒体使用量(无运行时间) await using 还没有)

const car = fromStream(stream);

try {
    for await (const entry of car) {
        entry;
        // ^? CarEntry { ... }
    }
} finally {
    await car.dispose();
}

同步使用

const buffer = Uint8Array.from([/* ... */]);

// read generic CAR archives
const car = fromUint8Array(buffer);

const roots = car.roots;

for (const entry of car) {
    entry;
    // ^? CarEntry { cid: CidLink {}, bytes: Uint8Array {}, ... }
}

写作

import { writeCarStream } from '@atcute/car';

const blocks = async function* () {
    yield { cid: commitCid.bytes, data: commitBytes };
    yield { cid: nodeCid.bytes, data: nodeBytes };
};

for await (const chunk of writeCarStream([rootCid], blocks())) {
    stream.write(chunk);
}
