fast-pug

When you use jade for client side (like with angular), you don't always need dynamic features or fancy features that jade provided. This is where fast-pug comes in. If you use gulp, you can use gulp-fast-pug.

installation:

• for python sudo pip install jade
• for nodejs npm install fast-pug

performance: 500~1500 times faster than jadejs/jade(1.11.0) in my project around 175 jade files (~250kB)

read: 29.708ms
fast-pug: 2.348ms
jadejs/jade: 3190.300ms

• #id
• .a.b.c
• tag
• above3(a,b="a",c=1)
• above4 text

• // jade comments and <!-- html --> comments are ignored
• experimental '.' block support, Eg. script.
• < one liner html tags will keep as is

• does not support stacked tags a: b: c. if program encounter ':', the whole program will exit.
