when all you needed was a contact form, anyways.

• Save the mail: Contact form saves messages to a local .mbox file
• Read the mail with something like: mutt -Rf cosgo.mbox
• Option to send mail using Sendgrid
• Option to use GPG for encrypting the messages
• Customize: Uses Go style templates, templates/index.html and templates/error.html
• Static Files: /sitemap.xml /favicon.ico, /robots.txt. Limited to .woff, .ttf, .css, .js .png .jpg and custom -ext flag
• You can stuff .zip, .tgz. .tar, .tar.gz files in /files/ and cosgo will serve them, too.
• Easy to convert static web sites to cosgo template.

See newest version in action at https://cosgo.herokuapp.com/

Releases:

1. Extract the archive.
2. Copy the binary to /usr/local/bin/ ( or extract everything to C:/cosgo/ )
3. Run cosgo from the command line. This will listen on all interfaces, port 8080.
4. Edit templates, static files

Building from source:

# Grab latest source code ( also check https://isupon.us )
git clone https://github.com/aerth/cosgo.git && cd cosgo
# make deps # optional, cosgo comes with vendor directory.

# Build a static binary
CGO_ENABLED=0 make

# Install to /usr/local/bin/cosgo
sudo make install

Customize the theme by modifying ./templates/index.html and ./templates/error.html Included in the binary is the bare minimal. o If they don't exist, the templates and static directories will be created where you run cosgo from. (since v0.9) Upload your static .css .js .png .jpeg .woff and .ttf files in ./static/ like /static/{foldername}/whatever.css, they will be available like any typical static file server. Some web design themes look in /assets, which won't be served by cosgo. s/assets/static/

cp favicon into static/ too. it will be served as if it were located at /favicon.ico

cp robot.txt into static/ too. it will be served at /robots.txt

• Make sure your template starts with {{define "Index"}}

• Make sure your template ends with {{end}}

• And is named index.html

• Your form needs {{ .csrfField }} and action="/{{.Key}}/send" method="POST"

• The minimal captcha stuff would be:

<p><img id="image" src="/captcha/{{.CaptchaId}}.png" alt="Captcha image"></p> ,

<input type=hidden name=captchaId value="{{.CaptchaId}}" />

and something like:

<input name=captchaSolution placeholder="Enter the code to proceed" />

All your static files should be neatly organized in /static/css/*.css to be used with the templates.

error.html: {{define "Error"}} Houston: We have a {{.err}} problem. {{end}}

or with fastcgi:

        location / {

        fastcgi_pass 127.0.0.1:8080; # no https:// with fastcgi
        include $fastcgi_params;
        }

}

Please add your use case. It could make cosgo better. Report any bugs or feature requests directly at https://isupon.us ( running casgo with a pixelarity theme )

• Casgo is short for "Contact API server in Golang"
• Turns out theres another casgo. Now this is cosgo.
• Cosgo is still not to be confused with Costco, the warehouse-style superstore.
• It began as a fork of https://github.com/munrocape/staticcontact
