@actions/tool-cache

Functions necessary for downloading and caching tools.

Usage

Download

You can use this to download tools (or other files) from a download URL:

const tc = require('@actions/tool-cache');

const node12Path = await tc.downloadTool('http://nodejs.org/dist/v12.7.0/node-v12.7.0-linux-x64.tar.gz');

Extract

These can then be extracted in platform specific ways:

const tc = require('@actions/tool-cache');

if (process.platform === 'win32') {
  tc.downloadTool('http://nodejs.org/dist/v12.7.0/node-v12.7.0-win-x64.zip');
  const node12ExtractedFolder = await tc.extractZip(node12Path, 'path/to/extract/to');
  
  // Or alternately
  tc.downloadTool('http://nodejs.org/dist/v12.7.0/node-v12.7.0-win-x64.7z');
  const node12ExtractedFolder = await tc.extract7z(node12Path, 'path/to/extract/to');
}
else {
  const node12Path = await tc.downloadTool('http://nodejs.org/dist/v12.7.0/node-v12.7.0-linux-x64.tar.gz');
  const node12ExtractedFolder = await tc.extractTar(node12Path, 'path/to/extract/to');
}

Cache

Finally, you can cache these directories in our tool-cache. This is useful if you want to switch back and forth between versions of a tool, or save a tool between runs for private runners (private runners are still in development but are on the roadmap).

You'll often want to add it to the path as part of this step:

const tc = require('@actions/tool-cache');
const core = require('@actions/core');

const node12Path = await tc.downloadTool('http://nodejs.org/dist/v12.7.0/node-v12.7.0-linux-x64.tar.gz');
const node12ExtractedFolder = await tc.extractTar(node12Path, 'path/to/extract/to');

const cachedPath = await tc.cacheDir(node12ExtractedFolder, 'node', '12.7.0');
core.addPath(cachedPath);

You can also cache files for reuse.

const tc = require('@actions/tool-cache');

tc.cacheFile('path/to/exe', 'destFileName.exe', 'myExeName', '1.1.0');

Find

Finally, you can find directories and files you've previously cached:

const tc = require('@actions/tool-cache');
const core = require('@actions/core');

const nodeDirectory = tc.find('node', '12.x', 'x64');
core.addPath(nodeDirectory);

You can even find all cached versions of a tool:

const tc = require('@actions/tool-cache');

const allNodeVersions = tc.findAllVersions('node');
console.log(`Versions of node available: ${allNodeVersions}`);
