Function loadComponentTemplate

loadComponentTemplate(
classDecl: ClassDeclaration,
options?: ComponentTemplateOptions,
): ComponentTemplateSource | undefined
Loads the template of an Angular component. This is the single entry point for reading a component template: it handles both template: literals and templateUrl: files, reads external files through the ts-morph file system (so in-memory projects work), and maps offsets back to line/column positions in the file that holds the text.

Returns undefined when the class is not a component, declares neither template nor templateUrl, or the external file cannot be read.
Parameters
- classDecl: ClassDeclaration
- Optionaloptions: ComponentTemplateOptions
Returns ComponentTemplateSource | undefined
Example
```
const source = loadComponentTemplate(classDecl);
if (source) {
  const { line } = source.locate(source.content.indexOf('*ngFor'));
  console.info(`${source.file}:${line}`);
}
```
