How do you specify angular template compiler options?

The angular template compiler options are specified as members of the angularCompilerOptions object in the tsconfig.json file. These options will be specified adjacent to typescript compiler options.

{
"compilerOptions": {
"experimentalDecorators": true,
...
},
"angularCompilerOptions": {
"fullTemplateTypeCheck": true,
"preserveWhitespaces": true,
...
}
}
