12 @command{godlighty} is highly-customizable HTTP, HTTP/2, HTTPS server
15 Why yet another web-server? Because all others suck even for my simple
16 ordinary needs: they use hateful OpenSSL, lacks documentation, has
17 complex configuration format, lack some features, hard to extend with.
21 @item Rather minimalistic pure-Go web-server with few number of
22 dependencies, producing single statically linked executable. Maximal
23 reuse of native libraries capabilities.
25 @item Modern, reliable, secure and fast TLS 1.3 implementation with
26 ChaCha20-Poly1305, session resumption and GOST cryptography (if built
27 with @url{http://www.gostls13.cypherpunks.ru/, gostls13}). SNI supported.
29 @item HTTP/1.1, @url{https://en.wikipedia.org/wiki/HTTP%2F2, HTTP/2}
30 (only when negotiated during ALPN) and keepalives support. Graceful
33 @item @code{gzip} and @url{https://facebook.github.io/zstd/, Zstandard}
34 compression on-the-fly.
36 @item @code{Range}, @code{ETag} (based on file/directory's
37 @code{ctime}), @code{Last-Modified} and corresponding precondition
38 handlers are fully used.
40 @item Auto-generated directory listings and
41 read-only @url{https://en.wikipedia.org/wiki/WebDAV, WebDAV} support.
43 @item If corresponding @file{.meta4} files are found, then @code{Link}
44 header is generated automatically to that
45 @url{http://www.metalinker.org/, Metalink}.
47 @item Very friendly to @url{http://cr.yp.to/daemontools.html, daemontools}.
48 Can drop (UID, GID, groups) privileges.
52 Basically all configuration is done directly inside source code.
53 Initially @command{godlighty} has basic static files handlers (with
54 compression, HTTP preconditions are enabled of course). In the example
55 below there are nearly all default functions.
58 Hosts["example.com"] = &godlighty.HostCfg{
59 Root: "/www/example.com",
60 TLS: &godlighty.TLSCfg{
61 Cert: "/path/to/example.com.pem",
62 Key: "/path/to/example.com.key.pem",
63 CACert: "/path/to/ca.pem",
67 MIMEOverride: map[string]string{
68 ".special": "text/x-special-type",
73 If your keys and certificates are in single file and you use common CA
74 certificate, then it is trivial to DRY:
79 CACert = path.Join(Etc, "ca.pem")
82 func newTLSCfg(host string) *godlighty.TLSCfg {
83 return &godlighty.TLSCfg{
84 Cert: path.Join(Etc, host+".pem"),
85 Key: path.Join(Etc, host+".pem"),
91 But there are hooks that can do anything more. For example if you want
92 to run CGI script or make a redirection:
97 Hooks: []godlighty.Hook{
98 func(w http.ResponseWriter, r *http.Request) bool {
99 if r.URL.Path == "/" {
100 http.Redirect(w, r, "//here.we.go/", http.StatusMovedPermanently)
105 func(w http.ResponseWriter, r *http.Request) bool {
107 Path: "/usr/local/libexec/git-core/git-http-backend",
110 "GIT_PROJECT_ROOT=" + root,
111 "GIT_HTTP_EXPORT_ALL=",

142 func addStaticCfg(host, root string) {
143 if !path.IsAbs(root) {
144 root = path.Join(WWW, root)
146 godlighty.Hosts[host] = &godlighty.HostCfg{
148 TLS: newTLSCfg(host),
152 func addStaticListedDir(host, root string) {
153 addStaticCfg(host, root)
154 godlighty.Hosts[host].DirList = true
155 godlighty.Hosts[host].WebDAV = true
160 addStaticCfg("paster.stargrave.org", "/storage/paster/pastes")
161 addStaticCfg("www.godlighty.stargrave.org", "godlighty.stargrave.org")
162 addStaticCfg("www.nncpgo.org", "nncpgo.org")
163 addStaticListedDir("www.mds.cypherpunks.ru", "/storage/audiobook/mds")
168 It is created exclusively to drive my own websites, but if you are
169 interested, then @code{git clone git://git.stargrave.org/godlighty.git} it.
