pub-time

A much better npm publish, that:

• performs automatic semantic release versioning, like semantic-release
• has zero dependencies - uses your built-in git, npm
• integrates with your npm scripts like build, test and lint
• checks your package.json for invalid types
• includes an API (including TypeScript support)
• supports a --dry-run option to give it a test drive

Release

If "checks" fail or "runs script" has nonzero error code, pub-time exits and the publish is cancelled.

1. checks you are on local main branch

2. checks you are level with remote origin/main

3. checks various key fields in package.json

4. checks for a README.md

5. checks that npm audit shows no vulnerabilities

6. runs script npm run lint if it exists (with default setting)

7. calculates the next version by looking at both:

   • the latest version (if any) published to npm
   • commits since the previous git tag v#.#.#

8. final warning, pausing for user input and showing some common final todos that can't be automatically checked

9. updates the version in package.json

10. checks that the user's npm and node versions match the user's engines in package.json

11. deletes and reinstalls npm dependencies

12. runs script npm run build (with default setting)

13. runs script npm run test (with default setting)

14. runs script npm run check-build if it exists (with default setting)

15. (!) dry run stops doing anything here, but instead logs out the commands it would run

16. releases

    • commits any changes
    • creates a new v#.#.# git tag
    • pushes up commits and tag
    • npm publish 🎉

Background

I created this library because I was unhappy with the alternatives (especially the install size):

package	install size
np
release-it
semantic-release

pub-time leans into the conventions you may already use in your projects and will use your pre-existing project specific scripts in your package.json.

Install

This package is available from the npm registry.

npm install pub-time

Usage

npx pub-time
# Options:
#   --dry-run |
#   1ad4719d1 | custom commit hash override (manually specify previous release commit)

API

Supports JavaScript + TypeScript:

import { publish } from "pub-time";

export const publish = (config: Partial<Config>) => Promise<boolean>;

export type Config = {
  /* custom log function instead of console.log */
  log: (message: string) => void;
  /* if true, package will not be published, git will not be updated */
  dryRun: boolean;
  /* if left undefined, will treat last 'v#.#.#' git tag as the last commit of the prev release
     if a string, will be treated as the hash of the last commit of the prev release
     to force include all commits, use the value 'all' */
  prevHash?: string;
  /* custom functions used in publish process */
  build: string | ((nextSemver: string) => Promise<void>);
  checkBuild: string | ((nextSemver: string) => Promise<void>);
  test: string | (() => Promise<void>);
  lint: string | (() => Promise<void>);
};

export const DEFAULT_CONFIG: Config = {
  // eslint-disable-next-line no-console
  log: console.log,
  prevHash: undefined,
  dryRun: false,
  lint: "lint",
  build: "build",
  checkBuild: "check-build",
  test: "test",
};

Can also be imported via require("pub-time").
