A fabulous library for defining continuous pipelines for building, testing and releasing code libraries.

import { getToken } from "./get-token";
export async function githubAppJwt({ id, privateKey, now = Math.floor(Date.now() / 1000), }) {
    // When creating a JSON Web Token, it sets the "issued at time" (iat) to 30s
    // in the past as we have seen people running situations where the GitHub API
    // claimed the iat would be in future. It turned out the clocks on the
    // different machine were not in sync.
    const nowWithSafetyMargin = now - 30;
    const expiration = nowWithSafetyMargin + 60 * 10; // JWT expiration time (10 minute maximum)
    const payload = {
        iat: nowWithSafetyMargin,
        exp: expiration,
        iss: id,
    };
    const token = await getToken({
        privateKey,
        payload,
