+# Manipulating documents and entries
+
+This guide will explore TypeScript patterns for manipulating documents and entries in a Strapi v5 application, including how to leverage Strapi's `UID` and `Data` namespaces to interact with both generic and known entity types safely. If you're working on a TypeScript-based Strapi project, mastering these approaches will help you take full advantage of type safety and code completion, ensuring robust, error-free interactions with your application’s content and components.
+
+:::prerequisites
+
+- **Strapi Application:** A Strapi v5 application. If you don't have one, follow the [documentation](/dev-docs/quick-start) to get started.
+- **TypeScript:** Ensure TypeScript is set up in your Strapi project. You can follow Strapi's [official guide](/dev-docs/typescript#getting-started-with-typescript-in-strapi) on configuring TypeScript.
+- **Generated Types:** Application types [have been generated](/dev-docs/typescript/development#generate-typings-for-content-types-schemas) and are accessible.
+ :::
+
+## Type Imports
+
+The `UID` namespace contains literal unions representing the available resources in the application.
+
+```typescript
+import type { UID } from '@strapi/strapi';
+```
+
+- `UID.ContentType` represents a union of every content-type identifier in the application
+- `UID.Component` represents a union of every component identifier in the application
+- `UID.Schema` represents a union of every schema (content-type or component) identifier in the application
+- And others...
+
+---
+
+Strapi provides a `Data` namespace containing several built-in types for entity representation.
+
+```typescript
+import type { Data } from '@strapi/strapi';
+```
+
+- `Data.ContentType` represents a Strapi document object
+- `Data.Component` represents a Strapi component object
+- `Data.Entity` represents either a document or a component
+
+:::tip
+Both the entities' type definitions and UIDs are based on the generated schema types for your application.
+
+In case of a mismatch or error, you can always [regenerate the types](/dev-docs/typescript/development#generate-typings-for-content-types-schemas).
+:::
+
+## Usage
+
+### Generic entities
+
+When dealing with generic data, it is recommended to use non-parametrized forms of the `Data` types.
+
+#### Generic documents
+
+```typescript
+async function save(name: string, document: Data.ContentType) {
+ await writeCSV(name, document);
+ // ^ {
+ // id: Data.ID;
+ // documentId: string;
+ // createdAt?: DateTimeValue;
+ // updatedAt?: DateTimeValue;
+ // publishedAt?: DateTimeValue;
+ // ...
+ // }
+}
+```
+
+:::warning
+In the preceding example, the resolved properties for `document` are those common to every content-type.
+
+Other properties have to be checked manually using type guards.
+
+```typescript
+if ('my_prop' in document) {
+ return document.my_prop;
+}
+```
+
+:::
+
+#### Generic components
+
+```typescript
+function renderComponent(parent: Node, component: Data.Component) {
+ const elements: Element[] = [];
+ const properties = Object.entries(component);
+
+ for (const [name, value] of properties) {
+ // ^ ^
+ // string any
+ const paragraph = document.createElement('p');
+
+ paragraph.textContent = `Key: ${name}, Value: ${value}`;
+
+ elements.push(paragraph);
+ }
+
+ parent.append(...elements);
+}
+```
+
+### Known entities
+
+When manipulating known entities, it is possible to parametrize `Data` types for better type safety and code completion.
+
+#### Known documents
+
+```typescript
+const ALL_CATEGORIES = ['food', 'tech', 'travel'];
+
+function validateArticle(article: Data.ContentType<'api::article.article'>) {
+ const { title, category } = article;
+ // ^? ^?
+ // string Data.ContentType<'api::category.category'>
+
+ if (title.length < 5) {
+ throw new Error('Title too short');
+ }
+
+ if (!ALL_CATEGORIES.includes(category.name)) {
+ throw new Error(`Unknown category ${category.name}`);
+ }
+}
+```
+
+#### Known components
+
+```typescript
+function processUsageMetrics(
+ id: string,
+ metrics: Data.Component<'app.metrics'>
+) {
+ telemetry.send(id, { clicks: metrics.clicks, views: metrics.views });
+}
+```
+
+### Advanced use cases
+
+#### Entities subsets
+
+Using the types' second parameter (`TKeys`), it is possible to obtain a subset of an entity.
+
+```typescript
+type Credentials = Data.ContentType<'api::acount.acount', 'email' | 'password'>;
+// ^? { email: string; password: string }
+```
+
+```typescript
+type UsageMetrics = Data.Component<'app.metrics', 'clicks' | 'views'>;
+// ^? { clicks: number; views: number }
+```
+
+#### Type argument inference
+
+It is possible to bind and restrict an entity type based on other function parameters.
+
+In the following example, the `uid` type is inferred upon usage as `T` and used as a type parameter for the `document`.
+
+```typescript
+import type { UID } from '@strapi/strapi';
+
+function display<T extends UID.ContentType>(
+ uid: T,
+ document: Data.ContentType<T>
+) {
+ switch (uid) {
+ case 'api::article.article': {
+ return document.title;
+ // ^? string
+ // ^? Data.ContentType<'api::article.article'>
+ }
+ case 'api::category.category': {
+ return document.name;
+ // ^? string
+ // ^? Data.ContentType<'api::category.category'>
+ }
+ case 'api::account.account': {
+ return document.email;
+ // ^? string
+ // ^? Data.ContentType<'api::account.account'>
+ }
+ default: {
+ throw new Error(`unknown content-type uid: "${uid}"`);
+ }
+ }
+}
+```
+
+When calling the function, the `document` type needs to match the given `uid`.
+
+```typescript
+declare const article: Data.Document<'api::article.article'>;
+declare const category: Data.Document<'api::category.category'>;
+declare const account: Data.Document<'api::account.account'>;
+
+display('api::article.article', article);
+display('api::category.category', category);
+display('api::account.account', account);
+// ^ ✅
+
+display('api::article.article', category);
+// ^ Error: "category" is not assignable to parameter of type ContentType<'api::article.article'>
+```
