BABEL Note: The code generator has deoptimised the styling of "app.js" as it exceeds the max of "100KB in Meteor
This is not a real issue. Just a warning. When babel compiles some code, it try to offer a readable output, but when files become big (>100KB), babel considers (by default) that it's not useful to keep this option enabled (because yes it's an option, see https://stackoverflow.com/a/30879872/988941 for more information).
It's not a problem to keep it. If you don't care about readability, you can just use compact: true
. Or false
if you do. Only "auto"
value (default value) will print this warning.
At first for more explanation read the Babel documentation on Options.
It is a common option of Babel compiler
that commands not include superfluous whitespace characters and line terminators. sometimes ago its threshold was 100KB
but now is 500KB
.
And I advise to you disable this option in your development environment, with this code in .babelrc
file.
{
"env": {
"development" : {
"compact": false
}
}
}
For production environment Babel
use the default config which is auto
.
