Fix logic of error handling for npm warning and uncaught exception

In scope of this release we fix logic of error handling related to caching (#358) and (#359).

In the previous behaviour we relied on stderr output to throw error. The warning messages from package managers can be written to the stderr's output. For now the action will throw an error only if exit code differs from zero. Besides, we add logic to сatch and log unhandled exceptions.

Adding Node.js version file support

In scope of this release we add the node-version-file input and update actions/cache dependency to the latest version.

Adding Node.js version file support

The new input (node-version-file) provides functionality to specify the path to the file containing Node.js's version with such behaviour:

• If the file does not exist the action will throw an error.
• If you specify both node-version and node-version-file inputs, the action will use value from the node-version input and throw the following warning: Both node-version and node-version-file inputs are specified, only node-version will be used.
• For now the action does not support all of the variety of values for Node.js version files. The action can handle values according to the documentation and values with v prefix (v14)

steps:
  - uses: actions/checkout@v2
  - name: Setup node from node version file
    uses: actions/setup-node@v2
    with:
      node-version-file: '.nvmrc'
  - run: npm install
  - run: npm test

Update actions/cache dependency to 1.0.8 version.

We updated actions/cache dependency to the latest version (1.0.8). For more information please refer to the toolkit/cache.

Add "cache-hit" output

This release introduces a new output: cache-hit (#327).

The cache-hit output contains boolean value indicating that an exact match was found for the key. It shows that the action uses already existing cache or not. The output is available only if cache is enabled.

Support caching for mono repos and repositories with complex structure

This release introduces dependency caching support for mono repos and repositories with complex structure (#305).

By default, the action searches for the dependency file (package-lock.json or yarn.lock) in the repository root. Use the cache-dependency-path input for cases when multiple dependency files are used, or they are located in different subdirectories. This input supports wildcards or a list of file names for caching multiple dependencies.

Yaml example:

steps:
- uses: actions/checkout@v2
- uses: actions/setup-node@v2
  with:
    node-version: 14
    cache: npm
    cache-dependency-path: 'sub-project/package-lock.json'

For more examples of using cache-dependency-path input, see the Advanced usage guide.

Revert temporary fix

We had to disable pre-cached Node.js usage in the previous version due to the broken image cache. Now cache is fixed, so we can safely enable its usage again.
Thank you for understanding.

Revert temporary fix for v1

Temporary maintenance fix.

Temporarily disabled usage of pre-cached Node.js.

Support caching pnpm dependencies

This release introduces dependency caching support for the pnpm package manager (#278).

Caching pnpm dependencies:

# This workflow uses actions that are not certified by GitHub.
# They are provided by a third-party and are governed by
# separate terms of service, privacy policy, and support
# documentation.

steps:
- uses: actions/checkout@v2
- uses: pnpm/action-setup@646cdf48217256a3d0b80361c5a50727664284f2
  with:
    version: 6.10.0
- uses: actions/setup-node@v2
  with:
    node-version: '14'
    cache: 'pnpm'
- run: pnpm install
- run: pnpm test

NOTE: pnpm caching support requires pnpm version >= 6.10.0

Support caching dependencies and LTS aliases

This release brings two major features:

• Support LTS aliases #270
• Implementation of node's caching #272

Supported version syntax

The node-version input supports the following syntax:

major versions: 12, 14, 16
more specific versions: 10.15, 14.2.0, 16.3.0
nvm LTS syntax: lts/erbium, lts/fermium, lts/*

Caching dependencies

The action has a built-in functionality for caching and restoring npm/yarn dependencies. Supported package managers are npm, yarn. The cache input is optional, and caching is turned off by default.

Caching npm dependencies:

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

Caching yarn dependencies:

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

Yarn caching handles both yarn versions: 1 or 2.

At the moment, only lock files in the project root are supported.
