+## Avoid circular import errors
+
+Here is an example if you want to define your entities, and you don't want those to cause errors in some environments.
+In this situation we have Action.ts and Person.ts importing each other for a many-to-many relationship.
+We use import type so that we can use the type information without any JavaScript code being generated.
+
+```typescript
+import { Entity, PrimaryColumn, Column, ManytoMany } from "typeorm"
+import type { Person } from "./Person"
+
+@Entity()
+export class ActionLog {
+    @PrimaryColumn()
+    id: number
+
+    @Column()
+    date: Date
+
+    @Column()
+    action: string
+
+    @ManyToMany("Person", "id")
+    person: Person
+}
+```
+
+```typescript
+import { Entity, PrimaryColumn, ManytoMany } from "typeorm"
+import type { ActionLog } from "./Action"
+
+@Entity()
+export class Person {
+    @PrimaryColumn()
+    id: number
+
+    @ManyToMany("ActionLog", "id")
+    log: ActionLog
+}
+```
