Vue 2.0.7 - as small as it gets (near-perfect GZIP compression)

Choose a version:

The original file has 203441 bytes (198.7k) and is available from the project website.
There you can find the official minified version, too, which brings down the size to 66982 bytes (65.4k, 33%).

After GZIP compression these minified files vary in size:

Boot	28127 bytes (27.5k)	CDN
cdnjs	24712 bytes (24.1k)	CDN
unpkg	24560 bytes (24.0k)	CDN
gzip -6 (default)	24557 bytes (24.0k)	local copy
gzip -9	24536 bytes (24.0k)	local copy
jsdelivr	24521 bytes (23.9k)	CDN
7zip -mx=9 -tgzip	23771 bytes (23.2k)	local copy
kzip -s0 -rn -b3	23753 bytes (23.2k)	local copy
libdeflate -12	23747 bytes (23.2k)	local copy
zultra	23732 bytes (23.2k)	local copy
pigz -11 -n	23726 bytes (23.2k)	local copy
Zopfli	23661 bytes (23.1k)	local copy

perma-link to the smallest file on my server:
http://minime.stephan-brumme.com/files/vue/vue-2.0.7.min.js (or via HTTPS)

You will automatically get the smallest Vue 2.0.7 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 860 bytes by using my Vue 2.0.7 Zopfli version instead of the best available CDN (3.63% smaller than jsdelivr, 23661 vs. 24521 bytes):

Download

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 --mls4096 --bsr22 --lazy --ohh

(found April 6, 2017)

Description	Value	Parameter
iterations	100000	--i100000
maximum blocks	8	--mb8
maximum length score	4096	--mls4096

Verify file integrity

After decompression, my uncompressed files are identical to the original ones:

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	23672 bytes	–	100%
1,000	23670 bytes	-2 bytes	100%
10,000	23665 bytes	-5 bytes	100%
100,000	23661 bytes	-4 bytes	1.16%
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

1	23757 bytes	+96 bytes (+0.41%)	+4 bytes
2	23754 bytes	+93 bytes (+0.39%)	+1 byte

8	23866 bytes	+205 bytes (+0.87%)	+113 bytes

Non-DEFLATE Algorithms

Archivers based on completely different compression algorithms often produce superior results.
Unfortunately, browsers only support gzip compression at the moment.
However, support for Brotli is constantly growing - for example, your browser actually supports it !

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):

Load and Parse Data

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.
