Forgejo Docs - v7.0

Compiling from source

Installation from source

You should install go and set up your go environment correctly. In particular, it is recommended to set the $GOPATH environment variable and to add the go bin directory or directories ${GOPATH//://bin:}/bin to the $PATH. See the Go wiki entry for GOPATH.

Next, install Node.js with npm which is required to build the JavaScript and CSS files. The minimum supported Node.js version is 20.

Note: When executing make tasks that require external tools, like make misspell-check, Forgejo will automatically download and build these as necessary. To be able to use these, you must have the "$GOPATH/bin" directory on the executable path.

Note 2: Go version 1.22 or higher is required. However, it is recommended to obtain the same version as the continuous integration.

Note 3: If you want to avoid installing build dependencies manually, you can also build the Docker image, which runs the build process in a Docker image containing all the required dependencies.

Download

First, we must retrieve the source code.

Terminal window
git clone https://codeberg.org/forgejo/forgejo

Decide which version of Forgejo to build and install. Currently, there are multiple options to choose from. The forgejo branch represents the current development version.

To work with tagged releases, the following commands can be used:

Terminal window
git branch -a
git checkout v7.0.3

To build Forgejo from source at a specific tagged release (like v7.0.3), list the available tags and check out the specific tag.

List available tags with the following.

Terminal window
git tag -l
git checkout v7.0.3

Build

To build from source, the following programs must be present on the system:

  • go v1.22 or higher, see here
  • node 20 or higher with npm, see here
  • make

There are a number of useful make targets, only some of which are documented here. They can all be displayed with:

Terminal window
$ make help
Make Routines:
 - ""                               equivalent to "build"
 - build                            build everything
 - frontend                         build frontend files
 - backend                          build backend files
 - watch                            watch everything and continuously rebuild
 - watch-frontend                   watch frontend files and continuously rebuild
 - watch-backend                    watch backend files and continuously rebuild
...

Depending on requirements, the following build tags can be included.

  • bindata: Build a single monolithic binary, with all assets included. Required for production build.
  • sqlite sqlite_unlock_notify: Enable support for a SQLite3 database. Suggested only for small installations.
  • pam: Enable support for PAM (Linux Pluggable Authentication Modules). Can be used to authenticate local users or extend authentication to methods available to PAM.

Using the bindata build tag is required for production deployments. You could exclude bindata when you are developing/testing Forgejo or able to separate the assets correctly.

To include all assets, use the bindata tag:

Terminal window
TAGS="bindata" make build

In the default release build of the continuous integration system, the build tags are: TAGS="bindata timetzdata sqlite sqlite_unlock_notify". The simplest recommended way to build from source is therefore:

Terminal window
TAGS="bindata timetzdata sqlite sqlite_unlock_notify" make build

The build target is split into two sub-targets:

  • make backend which requires Go v1.22 or greater.
  • make frontend which requires Node.js 20 or greater.

If pre-built frontend files are present it is possible to only build the backend:

Terminal window
TAGS="bindata" make backend

Webpack source maps are by default enabled in development builds and disabled in production builds. They can be enabled by setting the ENABLE_SOURCEMAP=true environment variable.

Build the Docker image

To build Forgejo’s Docker image, you need to have Docker and the Docker Buildx plugin installed. You can build the Docker image with:

Terminal window
docker buildx build --output type=docker --tag forgejo:mybuild .

This will run the entire build process in a Docker container with the required dependencies. You can also supply a tag during the build process with the -t option, to make it easier to publish or run the image later.

Testing

See the section dedicated to testing.
