Cache dependencies in GitHub Actions on Windows-CodePudding

I am having a Github action which runs on Windows OS. Then, for caching the dependencies, I use the actions/cache@v2. But, it is not working as expected. When I saw the debug logs, the size of the cache is only about 30 B.

Here is the code I am using:

name: Build
on: push

jobs:
 build_on_win:
runs-on: windows-latest
if: "!contains(github.event.head_commit.message, 'skip-publish')"

steps:
  - uses: actions/checkout@v2
  - uses: actions/setup-node@master
    with:
      node-version: 15
  - name: Cache NPM dependencies
    uses: actions/cache@v2
    with:
      path: ~/.npm
      key: ${{ runner.OS }}-npm-cache-${{ hashFiles('**/package-lock.json') }}
      restore-keys: |
        ${{ runner.OS }}-npm-cache-
  - name: install dependencies
    run: npm install

  rest of the code..

Any help is greatly appreciated !

Caching package dependencies is a feature that is already available in the actions/setup-node@v2. You don't have to configure actions/cache@v2 and instead of that what you can do is use the setup-node@v2 action like below and you just have to add cache: 'npm' and it will automatically detect and will cache the dependencies.

steps:
- uses: actions/checkout@v2
- uses: actions/setup-node@v2
  with:
    node-version: '14'
    cache: 'npm'
- run: npm install
- run: npm test

If you have monorepo then you can also define the path

steps:
- uses: actions/checkout@v2
- uses: actions/setup-node@v2
  with:
    node-version: '14'
    cache: 'npm'
    cache-dependency-path: subdir/package-lock.json
- run: npm install
- run: npm test
