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.

v2.1.5 Release

Improve error and warning line number handling (problem matcher regex)

v2.1.4

The first stable release of actions/setup-node V2

v2.1.3 (beta)

• Add support for specifying architecture of Node.JS

v2.1.2 (beta)

• Updated communication with runner to use environment files rather then workflow commands

v1.4.4

• Updated communication with runner to use environment files rather then workflow commands

v1.4.3

This release includes vendored licenses for this action's npm dependencies.

v2.1.1 (beta)

Switch to main branch of node-versions repository to consume latest added versions.

v2.1.0 (beta)

Added check-latest input option to query the versions manifest for latest version before checking for semver match in local VM cache first (the default). That's useful for ensuring you get latest as soon as it's released to the cache but at the cost of perf / reliability (much more likely to incur and download and extract).

v2.0.0 (beta)

This is a beta release.

• Downloads LTS versions from node-versions releases for reliability. Falls back to nodejs.org dist on misses or failures
• Full semver spec support
• Support for upcoming GHES
