Package Exports

pkce-challenge

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (pkce-challenge) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Usage

Default length for the verifier is 43

const pkceChallenge = require("pkce-challenge");

pkceChallenge();

    code_challenge: 'CUZX5qE8Wvye6kS_SasIsa8MMxacJftmWdsIA_iKp3I'
}

Specify a verifier length

const challenge = pkceChallenge(128);

challenge.code_verifier.length === 128; // true

Challenge verification

const { verifyChallenge } = require("pkce-challenge");

verifyChallenge(challenge.code_verifier, challenge.code_challenge) === true; // true

Challenge generation from existing code verifier

const { generateChallenge } = require("pkce-challenge");

generateChallenge(challenge.code_verifier) === challenge.code_challenge; // true
