Do not store your license key directly in client-side source code if you are building a public-facing application where the source is exposed. Consider obfuscation or, ideally, keep the key on your backend and inject it at runtime via an environment variable (e.g., process.env.VUE_APP_AG_GRID_KEY ).
For webpack, use process.env.AG_GRID_KEY . For server-side rendering (Next.js, Nuxt), ensure the key is injected at build time. ag grid license key
