+# Ignore All Errors In A TypeScript File
+
+As of TypeScript 3.7, we can mark an entire TypeScript file to be ignored by
+the TypeScript compiler when it is doing static type checking.
+
+We can do this by adding the `@ts-nocheck` directive at the top of the file:
+
+```typescript
+// @ts-nocheck
+
+type User = {
+  id: string;
+  name: string;
+  email: string;
+}
+
+const user: User = {
+  id: 123,
+  name: "Liz Lemon",
+  email: "liz.lemon@nbc.com",
+};
+```
+
+Notice that `id` is typed as a `string`, but we are using a `number` with `id`
+for `user`. That is a type error. But with the `@ts-nocheck` directive at the
+top, the type checker doesn't run on the file and we see no type errors.
+
+I'd generally suggest to avoid doing this. It can hide real type errors that
+you should be addressing. That said, in special circumstances, you may need it,
+even if just temporarily, like if an imported package doesn't have types. Here
+is an example of that in [uploadthing's
+`rehype.js`](https://github.com/pingdotgg/uploadthing/blob/d98fbefedddf64d183cc5a00b3fd707e8d8f2f6c/docs/src/mdx/rehype.js#L1)
+which is missing types from `mdx-annotations`.
