Preprocessor config error in rollup.config.js after running setupTypeScript.js

[petercoulton]

#189 seems to introduce a bug in rollup.config.js after running setupTypeScript.js. Specifically the preprocess directive is being added to compilerOptions instead of to the svelte config:

Expected -

...
svelte({
	// enable run-time checks when not in production
	compilerOptions: {
		dev: !production
	},
 	preprocess: sveltePreprocess()
}),
...

Actual -

svelte({
	// enable run-time checks when not in production
	compilerOptions: {
		dev: !production,
		preprocess: sveltePreprocess()
	},
}),
...
