We have a library call quantr-spfx-library, which is a supporting library for our SPFx project. I tried to update a spfx project to 1.8.0 and unable to bundle it. The error is:
Using webpack.optimize.UglifyJsPlugin() in webpack.config throws SyntaxError: Unexpected token: name (l) . The code there is unreachable.
Here is the original code from our library:
export function widerDevMode() {
var l: string = location.href;
if (l.endsWith('workbench.aspx') || l.endsWith('workbench.html')) {
if (document.getElementById('workbenchPageContent') != null) {
(document.getElementById('workbenchPageContent') as HTMLElement).style.maxWidth = '1200px';
}
if (document.querySelector('.CanvasZone') != null) {
//document.getElementsByClassName('CanvasZone')[0].style.maxWidth='1600px';
(document.querySelector('.CanvasZone') as HTMLElement).style.maxWidth = '1200px';
}
if (document.querySelector('.ms-compositeHeader') != null) {
(document.querySelector('.ms-compositeHeader') as HTMLElement).style.display = 'none';
}
}
}
As you can see, in the second line of above code, we have a library which has a simple name “l”. After i rename it to something longer, the error disappear.
