File Uploads

Consider using the following code examples when uploading files.

Generate the upload checksum

Generating the checksum is required before uploading a file.

import { createSHA256 } from "hash-wasm";

export const generateSHA256Checksum = async (file: File) => {
    const sha256 = await createSHA256();
    const chunkSize = 10 * 1024 * 1024; // 10 MB
    const fileSize = file.size;
    for (let offset = 0; offset < fileSize; offset += chunkSize) {
        const chunk = file.slice(offset, offset + chunkSize);
        const buffer = await chunk.arrayBuffer();
        sha256.update(new Uint8Array(buffer));
    }
    const hashBuffer = sha256.digest("binary");
    return btoa(String.fromCharCode.apply(null, Array.from(hashBuffer)));
}

import hashlib
import base64
from pathlib import Path

def generate_sha256_checksum(file_path: Path) -> str:
    with file_path.open("rb") as f:
        hash_digest = hashlib.file_digest(f, "sha256").digest()
    return base64.b64encode(hash_digest).decode('utf-8')

Encode the file name

The encoded file name is required when uploading a file.

const encodedFileName = encodeURIComponent("file_name123%€.wav")

import urllib.parse

encoded_file_name = urllib.parse.quote("file_name123%€.wav", safe="-.!~*'()")
