 To specify the target in dev, the [`esbuild.target`](/config/shared-options.html#esbuild) option can be used, which defaults to `esnext` for minimal transpilation. In builds, the [`build.target`](/config/build-options.html#build-target) option takes higher priority over `esbuild.target` and can also be set if needed.
 
-::: warning `useDefineForClassFields`
-
-If `target` in `tsconfig.json` is not `ESNext` or `ES2022` or newer, or if there's no `tsconfig.json` file, `useDefineForClassFields` will default to `false` which can be problematic with the default `esbuild.target` value of `esnext`. It may transpile to [static initialization blocks](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes/Static_initialization_blocks#browser_compatibility) which may not be supported in your browser.
-
-As such, it is recommended to set `target` to `ESNext` or `ES2022` or newer, or set `useDefineForClassFields` to `true` explicitly when configuring `tsconfig.json`.
