How to find what node version a project supports? When developer not specify in documentation OR package.json (engine)

[abhint]

You can specify the version of the node running stuff using package.json.
if you want more please visit: https://docs.npmjs.com/cli/v9/configuring-npm/package-json#engines

{
  "engines": {
    "node": ">=0.10.3 <15"
  }
}

You don't understand my question. I am working on old project that does not specify a Node.js version in package.json. Like your reply. I have tried different Node.js versions, but they do not work.

I think you already know the answer: trial and error. You're probably hoping for an easier way out but there isn't one if your predecessor didn't write anything down.

Can you show the error?

How can find which node version is compatible from this?

[arpit9616]

If the project's required Node.js version isn't explicitly specified in the documentation or the package.json file, you can determine it by examining the GitHub release tags for all dependencies and inspecting their respective package.json files. This approach will allow you to derive a range of compatible Node.js versions, streamlining your analysis process.

For instance, let's consider the Angular framework as a central dependency. By referring to the specific version, such as "@angular/core": "~10.2.3", you can explore its dependency details. This may lead you to infer a compatible Node.js version range, such as ">=10.9.0 <13.0.0", based on the Angular version's supported engine range.

Though this investigation might be somewhat time-consuming, particularly when applied to major dependencies, this method should help you gain valuable insights into the required Node.js environment. By repeating this process for the primary dependencies, you should be able to approximate the appropriate Node.js version for your project.

Hope this helps.
