Is there anyway,we could extend this to accept class level public fields as?

[ashishyog]

Parser starts giving error "Only methods are allowed in class".

For below example:

class Rectangle {
height;
width;
constructor(height, width) {
this.height = height;
this.width = width;
}
}

any idea how could we support this?

We will add support for these in a future release. Currently, shift-parser-js supports only the features of ES2018.
