How to download binary?

[marcus2vinicius]

var data = template.generate();

using FileSaver.js

saveAs(data,"Rel.xlsx");

does not work

[ksafranski]

Try fs.writeFile (or writeFileSync) with encoding set to binary (see this test for full example)

fs.writeFileSync('test.xlsx', newData, 'binary')

As a note to the contributors, that little bit would make a nice addition to the docs/readme. It's a great lib and saved me a ton of time but I didn't think of the encoding on writeFile and kind of banged my head on something rather small till I found it in the test.

@Fluidbyte I seen this example, but in this case you need to save to disk before.
maybe so
