s3.js | a Root project

Minimalist S3 client

A lightweight alternative to the s3 SDK that uses only @root/request and aws4.

• set()
• get()
• head()
• delete()
• sign()

Download a file from S3

s3.get({
    accessKeyId,
    secretAccessKey,
    region,
    bucket,
    prefix,
    key
});

Upload a new file to S3

s3.set({
    accessKeyId,
    secretAccessKey,
    region,
    bucket,
    prefix,
    key,
    body,
    size
});

Return signed URL without fetching.

s3.sign({
    method: 'get',
    accessKeyId,
    secretAccessKey,
    region,
    bucket,
    prefix,
    key
});

If the body is a stream then size must be set to fs.statSync(filePath).size, or the request will fail:
