We’ve upgraded!

The old Fleek Storage SDK is now part of our all-new Fleek Platform SDK, which brings enhanced performance, new features, and broader support for all your web3 development needs. Head to https://www.npmjs.com/package/@fleek-platform/sdk to get started.

Fleek Storage Js

Fleek Storage Js is an SDK to interact with Fleek Storage.

❗ Please do not use this package directly in the browser. Your API secret will be visible to users of that page. If you need to make requests from the client side, please use an S3 SDK directly with pre-signed urls: https://docs.aws.amazon.com/AmazonS3/latest/userguide/using-presigned-url.html.

yarn add @fleekhq/fleek-storage-js

Importing

The SDK can be imported using an import statement.

import fleekStorage from '@fleekhq/fleek-storage-js'

The SDK can also be imported using a require.

const fleekStorage = require('@fleekhq/fleek-storage-js')

Getting Api Keys

The api key and secret can be generated on the Fleek Web app or from the Fleek CLI.

See Getting an Api Key

Methods

get

The get method is for fetching individual files, either the content or related data, such as the key, hash and publicUrl.

Example of usage:

const myFile = await fleekStorage.get({
  apiKey: 'my-key',
  apiSecret: 'my-secret',
  key: 'my-file-key',
  getOptions: [
    'data',
    'bucket',
    'key',
    'hash',
    'publicUrl'
  ],
})

Input parameters of get

param	type	description
apiKey	String	The api key used for authentication
apiSecret	String	The api secret used for authentication
key	String	The key identifying the requested file in the bucket
bucket	String, optional, defaults to the default account bucket	The name of the bucket containing the file. A bucket is created by default with every Fleek account
getOptions	Array, optional, defaults to ['data']	An array specifying what type of information to retrieve concerning the file. Possible values for the array includes data, bucket, hash, key, publicUrl

upload

The upload method uploads a file, identified by a key, to a bucket. The function returns the hash of the file, the publicUrl, the key and the bucket.

Example of usage:

fs.readFile(filePath, async (error, fileData) => {
  const uploadedFile = await fleekStorage.upload({
    apiKey: 'my-key',
    apiSecret: 'my-secret',
    key: 'my-file-key',
    data: fileData,
  });
})

Input parameters of upload

param	type	description
apiKey	String	The api key used for authentication
apiSecret	String	The api secret used for authentication
key	String	The key identifying the requested file in the bucket
bucket	String, optional, defaults to the default account bucket	The name of the bucket containing the file. A bucket is created by default with every Fleek account
data	Any	The data of the file to be uploaded

deleteFile

The deleteFile method deletes a file, identified by its key and bucket. The function returns the key and bucket of the deleted file if successful. If the file does not exist, the method will still execute successfully.

Example of usage:

  await fleekStorage.deleteFile({
    apiKey: 'my-key',
    apiSecret: 'my-secret',
    key: 'my-file-key',
    bucket: 'my-bucket',
  });

Input parameters of deleteFile

param	type	description
apiKey	String	The api key used for authentication
apiSecret	String	The api secret used for authentication
key	String	The key identifying the file in the bucket
bucket	String, optional, defaults to the default account bucket	The name of the bucket containing the file. A bucket is created by default with every Fleek account

listFiles

The listFiles method is for fetching information about all files in a bucket such as the key, hash and publicUrl.

Example of usage:

const files = await fleekStorage.listFiles({
  apiKey: 'my-key',
  apiSecret: 'my-secret',
  prefix: 'my-folder',
  getOptions: [
    'bucket',
    'key',
    'hash',
    'publicUrl'
  ],
})

Input parameters of listFiles

param	type	description
apiKey	String	The api key used for authentication
apiSecret	String	The api secret used for authentication
bucket	String, optional, defaults to the default account bucket	The name of the bucket containing the file. A bucket is created by default with every Fleek account
prefix	String, optional, defaults to the empty string	The name of the folder you want to list files in. Can be used to recurse through the folder structure in Fleek Storage
getOptions	Array, optional, defaults to ['key', 'bucket', 'publicUrl']	An array specifying what type of information to retrieve concerning the file. Possible values for the array includes bucket, hash, key, publicUrl

listBuckets

The listBuckets method returns an array of bucket names associated with the api key's account.

Example of usage:

const buckets = await fleekStorage.listBuckets({
  apiKey: 'my-key',
  apiSecret: 'my-secret',
})

Input parameters of listBuckets

param	type	description
apiKey	String	The api key used for authentication
apiSecret	String	The api secret used for authentication

getFileFromHash

getFileFromHash is a utility function that downloads a file's data from Fleek's IPFS gateway using the hash. The key and secret is not required since the gateway is publicly available.

Example of usage:

const myFile = await fleekStorage.getFileFromHash({
  hash: 'bafybeige4bhzjvrptn7fdz7mqgigzoczcliqpuo7km4jm7vgjg2pbmuhna',
  getFileFromHashOptions: [
    'buffer',
  ],
})

Input parameters of getFileFromHash

param	type	description
hash	String	The hash of the requested file
getFileFromHashOptions	Array, optional, defaults to []	An array specifying additional options when it comes to fetching by hash. Possible values for the array includes buffer (this returns the whole file at once instead of chunks)
