# Creating Templates

### Define a JSON Schema for a Template

Create a JSON schema directly or from a TypeScript interface:

```typescript
// Direct JSON Schema definition
const schema = {
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "properties": {
    "name": {"type": "string", "description": "The name of the organization."},
    "description": {"type": "string", "description": "A brief description of the organization."},
    "website": {"type": "string", "description": "The URL of the organization's website.", "format": "uri"}
  },
  "required": ["name"],
};

// Generate JSON schema from a TypeScript interface
const dataName = 'User';
const myDataType = `interface ${dataName} {
  name: string;
  age: number;
}`;
const schema = generateJsonSchema(dataName, myDataType);
```

### Create a New Template

Use the defined schema to create a new template:

```typescript
const metadata = { name: "Template Name", description: "Template Description", readme: "Markdown document" };  // Optional metadata
const template = await ctx.createTemplate("template_path", schema, [], metadata /* optional */);
```

### Installing Templates

Once we have the template, we can install it in a document by using the `install` method:

```typescript
const document = await ctx.document("document_path");
if (!document.success) {
    // Handle error
}
const templateArrayToInstall = ["template_path"];
const newDoc = await document.data.install(templateArrayToInstall);
```

### Uninstalling Templates

To uninstall a template from a document, we can use the `uninstall` method:

```typescript
const document = await ctx.document("document_path");
if (!document.success) {
    // Handle error
}
const templateArrayToUninstall = ["template_path"];
const newDoc = await document.data.uninstall(templateArrayToUninstall);
```
