setup-node
This action sets by node environment for use in actions by:
- optionally downloading and caching a version of node - npm by version spec and add to PATH
- registering problem matchers for error output
- configuring authentication for GPR or npm
v2-beta
A beta release which adds reliability for pulling node distributions from a cache of node releases is available by referencing the v2-beta
tag.
steps:
- uses: actions/checkout@v2
- uses: actions/setup-node@v2-beta
with:
node-version: '12'
The action will first check the local cache for a semver match. The hosted images have been updated with the latest of each LTS from v8, v10, v12, and v14. self-hosted
machines will benefit from the cache as well only downloading once. The action will pull LTS versions from node-versions releases and on miss or failure will fall back to the previous behavior of downloading directly from node dist.
The node-version
input is optional. If not supplied, the node version that is PATH will be used. However, this action will still register problem matchers and support auth features. So setting up the node environment is still a valid scenario without downloading and caching versions.
Usage
See action.yml
Basic:
steps:
- uses: actions/checkout@v2
- uses: actions/setup-node@v1
with:
node-version: '12'
- run: npm install
- run: npm test
Check latest version:
In the basic example above, the check-latest
flag defaults to false
. When set to false
, the action tries to first resolve a version of node from the local cache. For information regarding locally cached versions of Node on GitHub hosted runners, check out GitHub Actions Virtual Environments. The local version of Node in cache gets updated every couple of weeks. If unable to find a specific version in the cache, the action will then attempt to download a version of Node. Use the default or set check-latest
to false
if you prefer stability and if you want to ensure a specific version of Node is always used.
If check-latest
is set to true
, the action first checks if the cached version is the latest one. If the locally cached version is not the most up-to-date, a version of Node will then be downloaded. Set check-latest
to true
it you want the most up-to-date version of Node to always be used.
Setting
check-latest
totrue
has performance implications as downloading versions of Node is slower than using cached versions
steps:
- uses: actions/checkout@v2
- uses: actions/setup-node@v2
with:
node-version: '12'
check-latest: true
- run: npm install
- run: npm test
