Decentralized Storage
Slik offers you the ability to upload or download files to the decentralized web as a simple drop in NPM package.
Using the
slik-files package, you can enable a native upload and download experience for your users within your app. All files uploaded from the slik-files package are backed up to a decentralized storage and replicated across a globally distributed network of 10K+ nodes. API Keys
You can play around with the demo app that uses the slik-files SDK at: https://slikfilesdemo.web.app
To get started, please install the
@sliksafe/slik-files package in your app.Terminal
# Install via yarn
yarn add @sliksafe/slik-files
You can simply upload a file by calling the
uploadFile method after initializing the library. The upload method accepts different parameters based on your requirements, specified in detail below. React
// Import SlikFiles
import { SlikFiles } from '@sliksafe/slik-files'
// Initialize slik-files
const initParams = { apiKey: "api_key_string" }
const filesHandler = await SlikFiles.initialize(initParams)
// A file-like object with raw data. The File interface inherits from Blob.
// Assign the file object received after uploading a file.
let file: File =
// Upload a file with upload options
const uploadOptions = {
networks: ["filecoin"],
walletAddress: "0x5c14E7A5e9D4568Bb8B1ebEE2ceB2E32Faee1311",
file: file,
isEncrypted: false,
}
filesHandler.uploadFile(uploadOptions, (uploadHandle, fileId, err) => {
console.log("The unique identifier of the file uploaded: ", fileId);
if (!!err) {
console.error('Failed to upload file: ', err)
} else {
console.log("Uploading file progress: ", uploadHandle);
setUploadDownloadProgress(uploadHandle.percentage);
if (uploadHandle.status === "uploaded") {
console.log("File upload finished");
console.log("The unique identifier of the file uploaded: ", fileId);
}
}
});
Use the
uploadFile method in the slik-files package with the following parameters:File Upload Options | Data Type | Notes |
|---|---|---|
networks | string[] | An array of strings for networks. The different supported network values are: filecoin, storj, arweave, s3, gcs You can specify as many networks that you'd like while uploading files. |
file | File | Blob | |
walletAddress | string | Please provide the walletAddress of the user who is uploading the file.
(optional) |
isEncrypted | boolean | A boolean that indicates if the file is stored with end-to-end encryption on decentralized web.
The specified file is encrypted on the device before it is uploaded to the decentralized storage.
Default = false
(optional) |
After the file is uploaded the callback method is called with the unique
fileId. You can use this fileId to download the file using the downloadFile method. You can download a file using the same
fileHandler as initialized above and the downloadFile method. React
// Download a file with download options
const downloadOptions = {
fileId: "-N-ZESm8wbGeFuxpawPi",
walletAddress: "0x5c14E7A5e9D4568Bb8B1ebEE2ceB2E32Faee1311",
}
filesHandler.downloadFile(downloadOptions, (downloadHandle, file, err) => {
console.log("Downloading file progress: ", downloadHandle.percentage);
if (downloadHandle.status === "downloaded") {
console.log("File download finished");
console.log("Downloaded file: ", file);
}
});
Use the
downloadFile method in the slik-files package that takes the following parameters:File Upload Options | Data Type | Notes |
|---|---|---|
fileId | string | The unique identifier received after uploading a file.
|
walletAddress | string | Please provide the walletAddress of the user who is downloading the file.
(optional) |
After the file is downloaded a callback method is called with the unique
fileId and the file object that was downloaded. If the file was encrypted during upload, the
slik-files package would decrypt the file after it is downloaded. The
slik-files package automagically handles end-to-end encryption for you when you specify the isEncrypted flag during upload. When specified, each file is encrypted using military grade AES-256 symmetric key encryption, before it is stored on decentralized storage. Also, the file is seamlessly decrypted after being downloaded and before being returned back to you in the
downloadFile method.Encryption is disabled by default, so all files uploaded using this SDK are publicly downloadable and viewable on the decentralized web.
slik-files has a flexible pricing plan with no upfront costs and a pay-as-you-go model, where you are charged based on the size of the files uploaded and the network that they're uploaded to.Network | Price per GB uploaded |
|---|---|
Filecoin | $0.006 |
Storj | $0.006 |
Arweave (permanent storage) | $14.99 |
S3 | $0.03 |
Google Cloud Storage | $0.03 |
An additional egress cost is charged based on the size of file downloaded to handle the bandwidth used from the decentralized network of nodes.
Network | Price per GB downloaded |
|---|---|
Filecoin | $0.01 |
Storj | $0.01 |
Arweave | $0.01 |
S3 | $0.12 |
Google Cloud Storage | $0.12 |
The Slik infrastructure has been designed to scale with the needs of the developer. It is currently used by thousands of users worldwide to backup terabytes of data.
