Migrate from v1 to v2 beta

TIP

This page concerns projects created with DataProtector prior or equal to version 1.0.0

sh
npm install @iexec/dataprotector@beta --save-exact

Constructor

The instantiation process has been updated to accommodate new modular architecture introduced in version 2. This change allows for more flexibility and enables the use of specific functionalities tailored to the developers' needs.

When instantiating the IExecDataProtector object, reference the dataProtector property to use core methods. Newer versions allow to use extended methods using the dataProtectorSharing property.

js
// 1.0.0 and before
const dataProtector = new IExecDataProtector(web3Provider);

// AFTER 2.0.0
// with Umbrella Module
const dataProtector = new IExecDataProtector(web3Provider).dataProtector;
// Or with Core Module
const dataProtector = new IExecDataProtectorCore(web3Provider);

Methods

Some methods were renamed in order to standardize the SDK, they still provide the same functionalities as before.

Rename fetchProtectedData & add new filtering param

js
await dataProtector.fetchProtectedData({
await dataProtector.getProtectedData({
  owner: '0xa0c15e...',
  creationTimestampGte: 1707237580, // Feb 6th, 2024 16:39:40 GMT
});

Rename fetchGrantedAccess

js
await dataProtector.fetchGrantedAccess({
await dataProtector.getGrantedAccess({
  protectedData: '0x123abc...',
  authorizedApp: '0x456def...',
  owner: '0xa0c15e...',
});

Removed protectDataObservable

The protectDataObservable function has been removed and its functionality has been integrated into the protectData method with a new optional parameter. This parameter is a callback function that provides status updates during the data protection process. This change simplifies the API and enhances flexibility in handling the protection process status updates.

ts

const 
protectedData
= await
dataProtectorCore
.
protectData
({
name
: 'myEmail',
data
: {
email
: 'example@gmail.com',
},
onStatusUpdate
: ({
title
,
isDone
}) => {
console
.
log
(
title
,
isDone
);
}, });

Removed revokeAllAccessObservable

Similarly, the revokeAllAccessObservable method has been replaced for revokeAllAccess which does the same thing as revokeAllAccessObservable but includes an optional callback function parameter. This callback allows developers to receive feedback about the revocation status of the process, providing more control and better handling of the process.

ts

const 
allAccessRevoked
= await
dataProtectorCore
.
revokeAllAccess
({
protectedData
: '0x123abc...',
onStatusUpdate
: ({
title
,
isDone
}) => {
console
.
log
(
title
,
isDone
);
}, });

TIP

The introduction of callback functions in protectData and revokeAllAccess methods allows for real-time status updates, making the data protection and access revocation processes more interactive and manageable.

Protected Data Schema

The serialization of the data protected by protectData() has been changed to support a wider range of numbers, and extend the support for processing protected data in non-JS-based applications.

The new serialization mechanism is based on the borsh specification.

Consequently, the data schemas associated with protected data have changed.
