Multiline strings are gone when using uglifyify
opened this issue · comments
Comments are being stripped out in the final bundle when using uglifyify module.
To reproduce the issue, first install these modules:
# npm install -g watchify
# npm install uglifyify
Then just create a simple file test.js:
var multiline = require("multiline");
var str = multiline(function(){/*@preserve
<!doctype html>
<html>
<body>
<h1>❤ unicorns</h1>
</body>
</html>
*/console.log});
console.log("Starting multiline test:");
console.log(str);
console.log("Finished multiline test:");
First check the bundle.js is alright without uglifying the code:
> watchify test.js -o bundle.js -v
1911 bytes written to bundle.js (0.06 seconds)
> grep unicorns bundle.js
<h1>❤ unicorns</h1>
BUT when you use -t uglifyify transformation as explained in the documentation:
> watchify test.js -o bundle.js -v -t [uglifyify --comments]
1799 bytes written to bundle.js (0.13 seconds)
You'll see the multiline string isn't in the bundle anymore:
> grep unicorns bundle.js
Am I missing something here or is it a bug?
