Vue 1.0.15 - as small as it gets (near-perfect GZIP compression)

Choose a version:

The original file has 254252 bytes (248.3k) and is available from the project website.
There you can find the official minified version, too, which brings down the size to 72105 bytes (70.4k, 28%).

After GZIP compression these minified files vary in size:

Boot	28912 bytes (28.2k)	CDN
cdnjs	24981 bytes (24.4k)	CDN
gzip -6 (default)	24808 bytes (24.2k)	local copy
unpkg	24749 bytes (24.2k)	CDN
jsdelivr	24744 bytes (24.2k)	CDN
gzip -9	24722 bytes (24.1k)	local copy
libdeflate -12	23958 bytes (23.4k)	local copy
7zip -mx=9 -tgzip	23924 bytes (23.4k)	local copy
kzip -s0 -rn -b4	23879 bytes (23.3k)	local copy
pigz -11 -n	23859 bytes (23.3k)	local copy
zultra	23854 bytes (23.3k)	local copy
Zopfli	23821 bytes (23.3k)	local copy
Zopfli (defluff)	23818 bytes (23.3k)	local copy

perma-link to the smallest file on my server:
http://minime.stephan-brumme.com/files/vue/vue-1.0.15.min.js (or via HTTPS)

You will automatically get the smallest Vue 1.0.15 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 923 bytes by using my Vue 1.0.15 Zopfli version instead of the best available CDN (3.87% smaller than jsdelivr, 23821 vs. 24744 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 --mls16 --bsr20 --lazy --ohh

(found April 10, 2017)

Description	Value	Parameter
iterations	100000	--i100000
maximum blocks	8	--mb8
maximum length score	16	--mls16
block splitting recursion	20	--bsr20
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

Even Smaller Files Thanks To Defluff

Zopfli's output can be further optimized by the defluff tool.
In this particular case, defluff saves 3 more bytes (23818 bytes).

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	23835 bytes	–	100%
1,000	23825 bytes	-10 bytes	100%
10,000	23823 bytes	-2 bytes	100%
100,000	23821 bytes	-2 bytes	1.45%
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
(any)	23887 bytes	+66 bytes (+0.28%)	+8 bytes
1	23888 bytes	+67 bytes (+0.28%)	+9 bytes
2	23895 bytes	+74 bytes (+0.31%)	+16 bytes
3	23894 bytes	+73 bytes (+0.31%)	+15 bytes
4	23879 bytes	+58 bytes (+0.24%)	–
5	23912 bytes	+91 bytes (+0.38%)	+33 bytes
6	23947 bytes	+126 bytes (+0.53%)	+68 bytes
7	23982 bytes	+161 bytes (+0.68%)	+103 bytes
8	24015 bytes	+194 bytes (+0.81%)	+136 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 !

Algorithm	Program	Parameters	Size	Compared To Best Zopfli
ZPAQ (Wikipedia)	zpaq	zpaq -method 69	19775 bytes	-4046 bytes (-16.99%)

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.
