1. Install requisite dependencies

    # run local scripts for executing ts file for deploying docs
npm i -D @types/node
npm i -D ts-node

# semantic-release and plugin for attaching version number to package.json
npm i -D semantic-release
npm i -D @semantic-release/git

# git hooks and validate commit messages
npm i -D husky
npm i -D @commitlint/cli

  2. Add content to package.json

    {
  "scripts": {
    "deploy-docs": "ts-node tools/gh-pages-publish.ts",
    "semantic-release": "semantic-release"
  },
  "files": [
    "dist"
  ],
  // if package scoped like @bndynet/ui, by default private, so...
  "publishConfig": {
    "access": "public"
  },
  "husky": {
    "hooks": {
      "commit-msg": "commitlint -E HUSKY_GIT_PARAMS"
    }
  }
}

  3. New file .releaserc (Release Configurations)

    {
  "branch": "master",
  "prepare": [
    "@semantic-release/npm",
    {

      "assets": [
        "package.json",
        "package-lock.json"
      ],
      "message": "chore(release): ${nextRelease.version} by CI\\n\\n${nextRelease.notes}"
    }
  ],
  "plugins": [

    "@semantic-release/npm",
    "@semantic-release/github",

    language: node_js
cache:
  directories:
    - ~/.npm
notifications:
  email: false
node_js:
  - '10'
script:
  - npm run build
after_success:
  - if [ "$TRAVIS_BRANCH" = "master" -a "$TRAVIS_PULL_REQUEST" = "false" ]; then npm run deploy-docs; fi
  - if [ "$TRAVIS_BRANCH" = "master" -a "$TRAVIS_PULL_REQUEST" = "false" ]; then npm run semantic-release; fi
branches:
  except:
  - /^v\\d+\\.\\d+\\.\\d+$/

  5. New file tools/gh-pages-publish.ts (Scripts to upload docs to gh-pages branch)

    import { cd, exec, echo, touch } from "shelljs";
import { readFileSync } from "fs";
import { parse } from "url";

let repoUrl
let pkg = JSON.parse(readFileSync("package.json"))
if (typeof pkg.repository === "object") {
  if (!pkg.repository.hasOwnProperty("url")) {
    throw new Error("URL does not exist in repository section")
  }
  repoUrl = pkg.repository.url
} else {
  repoUrl = pkg.repository
}

let parsedUrl = parse(repoUrl)
let repository = (parsedUrl.host || "") + (parsedUrl.path || "")
let ghToken = process.env.GH_TOKEN

echo("Deploying docs!!!")
cd("docs")
touch(".nojekyll")
exec("git init")
exec("git add .")
exec('git config user.name "Bendy Zhang"')
exec('git config user.email "zb@bndy.net"')
exec('git commit -m "docs(docs): update gh-pages"')
exec(
`git push --force --quiet "<https://${ghToken}@$>{repository}" master:gh-pages`
)
echo("Docs deployed!!")
