The frontend presents user-facing web pages on pkg.go.dev.
For additional information on functionality of the frontend, see the design document.
The main program lives in
cmd/frontend. The bulk of the code lives in
See experiment.md for instructions how to enable experiments.
You can run the frontend locally like so:
go run ./cmd/frontend [-dev] [-direct_proxy]
The frontend can use one of three datasources:
Datasource interface implementation is available at internal/datasource.go.
You can use the
-direct_proxy flag to run the frontend with its datasource as the proxy service. This allows you to run the frontend without setting up a postgres database.
You can then run the frontend with:
go run ./cmd/frontend
If you add, change or remove any inline scripts in templates, run
devtools/cmd/csphash to update the hashes. Running
all.bash will do that as well.
You can also use run the frontend locally with an in-memory datasource populated with modules loaded from your local filesystem.
go run ./cmd/pkgsite [path1,path2]
This allows you to run the frontend without setting up a database and to view documentation of local modules without requiring a proxy. The command accepts a list of comma-separated strings each representing a path of a module to load into memory.
In addition to tests written in Go inside internal/frontend and internal/testing/integration, pages on pkg.go.dev may have accessibility tree and image snapshot tests. These tests will create diffs for inspection on failure. Timeouts and diff thresholds are configurable for image snapshots if adjustments are needed to prevent test flakiness. See the API for jest image snapshots for more information.
When modifying any TypeScript code, you must run
go run ./devtools/cmd/static before commiting your changes.
You can test html and static asset changes by running
npm test. This will run the TypeScript type checker and unit tests.
Lint your changes by running
npm run lint. This will run stylelint and eslint on CSS and TS files in content/static. You can autofix some errors by running
npm run lint -- --fix.
To run the the unit tests or linters without installing npm prefix the command with
./all.bash. This will run the npm through a docker container that has the pkgsite code mounted in an internal directory.
./all.bash npm run <command>
