Revel requires itself and the user application to be installed into a GOPATH layout as prescribed by the go command line tool. (See “GOPATH Environment Variable” in the go command documentation)
Below is the default layout of a Revel application called
sample, within a
typical Go installation.
my_gocode/- GOPATH root
src/- GOPATH src/ directory
github.com/revel/revel/- Revel source code
bitbucket.org/me/sample/- Sample app root
app/- app sources
tests/- test suites
conf/- configuration files
messages/- i18n message files
public/- static/public assets
css/- stylesheet files
images/- image files
app/ directory contains the source code and templates for your application.
Beyond that, the application may organize its code however it wishes. Revel
will watch all directories under
app/ and rebuild the app when it
notices any changes. Any dependencies outside of
app/ will not be watched for
changes – it is the developer’s responsibility to recompile when necessary.
Additionally, Revel will import any packages within
app/ (or imported
modules) that contain
init() functions on startup, to ensure
that all of the developer’s code is initialized.
app/init.go file is a conventional location to register all of the
interceptor hooks. The order of
init() functions is
undefined between source files from the same package, so collecting all of the
interceptor definitions into the same file allows the developer to specify (and
know) the order in which they are run. (It could also be used for other
order-sensitive initialization in the future.)
conf/ directory contains the application’s configuration files. There are
two main configuration files:
app.conf- the main configuration file for the application
routes- the URL routing definition file.
messages/ directory contains all localized message files.
Resources stored in the
public/ directory are static assets that are served
directly by the web server. Typically it is split into three standard
css/ stylesheets and
The names of these directories may be anything and the developer need only update the routes.
