EOSJS v21.0.0-rc1 Release Notes

This is a RELEASE CANDIDATE for version 21.0.0. The latest STABLE release is v20.0.0.

This Release Candidate can be accessed by running yarn add eosjs@RC.

Switch to elliptic cryptography library

eosjs-ecc has been replaced with the elliptic cryptographic library. The eosjs public API has been maintained; this is only a change to the internals.

Context-free Actions Support

Context-free actions are now supported in eosjs.

WebAuthn Support

Read more about WebAuthn support in the EOSIO 2.0 Medium article. For technical details, see the PR.

We have updated the Tropical Example app to demonstrate a use of Webauthn.

Conversion Helpers To/From elliptic lib's Format

elliptic stores keys and signatures differently than eosjs-ecc. For ease of use, conversion functions have been added. These are primarily located in src/eosjs-key-conversions.ts as well as re-exported in src/eosjs-jssig.ts. Usage examples of each can be found in src/tests/eosjs-jssig.test.ts. A glimpse of the functions follows:

// Private Key from EOSIO PUB_K1_ string format to `elliptic` and back
const privEllipticKey = PrivateKey.fromString(eosioK1PrivateKeyAsString).toElliptic();
const finalEosioKeyAsK1String = PrivateKey.fromElliptic(privEllipticKey).toString();

// Public Key from EOSIO PUB_K1_ string format to Elliptic and back
const ellipticPubKey = PublicKey.fromString(eosioK1PubKeyAsString).toElliptic();
const finalEosioKeyAsK1String = PublicKey.fromElliptic(ellipticPubKey).toString();

// Signature from EOS string format to `elliptic` and back
const ellipticSig = Signature.fromString(eosioSignatureAsString).toElliptic();
const finalEosioSignatureAsString = Signature.fromElliptic(ellipticSig).toString();

// Perform digest of data
digestFromSerializedData()  // wraps the construction of a digest from the data being digested
