Cross-platform solution for using multiple versions of node. Useful for compatibility testing
cli
# specific version
$ nvu 14.4.0 npm run test
# highest of version
$ nvu 12 npm run test
# lts
$ nvu lts npm run test
# comma-delimited list
$ nvu 0.8,4,8,14 npm run test
# use expression
$ nvu >=0.8 node --version
# use engines.node from package.json
$ nvu engines node --version
JavaScript
var assert = require('assert');
var nvu = require('node-version-use');
var NODE = process.platform === 'win32' ? 'node.exe' : 'node';
// results is an array per-version of form {version, error, result}
nvu('>=0.8', NODE, ['--version'], { versions: '12', stdio: 'inherit' }, function (err, results) {
assert.ok(!err);
});
// results is an array per-version of form {version, error, result}
await nvu('engines', NODE, ['--version'], { versions: '12', stdio: 'inherit' });
