Usage
Installation
$ npm i nodejs-version-checkerImporting
const nodeJSVersionChecker = require("nodejs-version-checker");Example
const nodeJSVersionChecker = require("nodejs-version-checker");
//Node version <=6.x.x
nodeJSVersionChecker({ node: "6.17.1", npm: "3.10.0"})
.then((result) => {
console.log(result);
})
.catch((error) => console.error(error));
//Node version >=6.x.x
(async () => {
try {
const result = await nodeJSVersionChecker();
console.log(result);
} catch (error) {
console.error(error);
}
})();

{ node:
{ current: '8.17.1',

{ current: '3.5.10',
expected: '3.10.0',
comparison: -1,
comparisonString: 'less' } }

// Default result if no parameters is passed
{ node: { current: '6.17.1' } }
Comparison mapping
-
comparison: 0: The local version is equal to the one expected -
comparison: 1: The local version is greater than the one expected -
comparison: -1: The local version is less than the one expected - If the key does not appear, it means that a comparison parameter was not passed
