How to check the backward compatibility of my node app with node version

Question

How can I check what's the oldest (not latest) version of Node can my application work on? Is there a package or a Node utility which can tell me this information?

Answer 1

No, in node.js there is the process.versions property to tell you what version you are running, for example:

Number(process.version.match(/^v(\d+\.\d+)/)[1])

if process.version is 'v0.11.5', then get 0.11 (Number)

But there is no package to tell you what's the oldest version of node your app can work on. You will have to figure it out on your own through testing, preferably unit test, in order to check the different version of node and the affect on your app. Then use the process version to match those findings.
