⚙ Implementation

Dependencies

• Node.js 18+

npm install @vedustorm/novacore

Code

import { login, login_silent, login_noexit } from "./license.js";

try {
    await login();
    // This does print the brief summary of LicenseCheck, no matter if mismatch occurs or not
  } catch (e) {
    console.error("Unexpected error:", e);
    process.exit(1);
}


try {
    await login_silent();
    // This doesn't print anything on successful check but if mismatch occurs it print what was mismatching
  } catch (e) {
    console.error("Unexpected error:", e);
    process.exit(1);
}

try {
    await login_noexit();
    // This prints summary; if mismatches exist, it does NOT exit.
  } catch (e) {
    console.error("Unexpected error:", e);
    process.exit(1);
}

// If you want to get license info from a json file not located at config/config.json but rather located at "path" then use
try{
    await login(path)
    await login_noexit(path)
    await login_silent(path)
} catch (e) {
    console.error("Unexpected error:", e);
    process.exit(1);
}

// It will exit (not the noexit one) if mismatches found and will continue running normally if not
