There you can find the official minified version, too, which brings down the size to 38659 bytes (37.8k, 34%).

perma-link to the smallest file on my server:
http://minime.stephan-brumme.com/files/vue/vue-0.9.3.min.js

You will automatically get the smallest Vue 0.9.3 file, ETag caching is available and
if your browser doesn't support GZIP decompression then the uncompressed version will be sent.

Currently best Zopfli settings

Save 483 bytes by using my Vue 0.9.3 Zopfli version instead of the best available CDN (3.77% smaller than unpkg, 12816 vs. 13299 bytes):
You can use my super-compressed files for whatever purpose you like as long as you respect the library's original license agreement.
There are no restrictions from my side - but please avoid hot-linking if you run a high-traffic website.

These command-line settings yielded the best compression ratio so far (Linux version of zopfli-krzymod):
zopfli --i100000 --mb8 --mls64 --bsr6 --lazy --ohh

(found April 9, 2017)
Description Value Parameter
iterations 100000  --i100000
maximum blocks 8  --mb8
maximum length score 64  --mls64
block splitting recursion 6  --bsr6
lazy matching in LZ77 yes  --lazy
optimized Huffman headers yes  --ohh
initial random W for iterations 1  --rw1
initial random Z for iterations 2  --rz2

Heatmaps

This Zopfli heatmap visualizes how compression changes when modifying the --bsr and --mls parameter.
Cell's contents is the best filesize achieved (in bytes, hover with mouse over cells to see number of iterations).

Good parameters are green, bad are red. The best and worst are bold as well.
The brightness of the blue background color indicates how many iterations were processed:
10,000 or 100,000.

Due to the Monte Carlo design of my search algorithm, not all parameters have reached the same number of iterations yet:
Iterations Min. Bytes Reduction Coverage
100 12821 bytes 100%
1,000 12819 bytes -2 bytes 100%
10,000 12817 bytes -2 bytes 100%
100,000 12816 bytes -1 byte 13.62%
1,000,000
10,000,000

KZIP has far less options available for tuning/optimization. I only played around with the number of blocks (parameter -n):
Blocks Min. Bytes Compared To Best Zopfli Compared To Best KZIP
12865 bytes +49 bytes (+0.38%) +11 bytes
12865 bytes +49 bytes (+0.38%) +11 bytes

12862 bytes +46 bytes (+0.36%) +8 bytes
12893 bytes +77 bytes (+0.60%) +39 bytes
12885 bytes +69 bytes (+0.54%) +31 bytes
12919 bytes +103 bytes (+0.80%) +65 bytes
12951 bytes +135 bytes (+1.05%) +97 bytes
12989 bytes +173 bytes (+1.35%) +135 bytes

Non-DEFLATE Algorithms

Archivers based on completely different compression algorithms often produce superior results.
Unfortunately, browsers only support gzip compression at the moment.

Detailled Analysis

I wrote a DEFLATE decoder in Javascript. Click the button below to start a client-side analysis of the smallest gzipped files (may take a second):


Notes: pigz is a fast open source multi-threaded implementation of gzip written by one of the original authors of gzip.
However, when using compression level 11, pigz actually switches to the slower Zopfli algorithm and isn't multi-threaded anymore.
KrzyMOD's extensions to Zopfli offer the highest level of configuration and is therefore used for my brute-force search.
Ken Silverman wrote the closed-source KZIP compression program and Jonathon Fowler ported it to Linux.
Defluff was created by Joachim Henke; DeflOpt is a tool by Ben Jos Walbeehm.
