# Screenshot Pipeline
|
|
|
|
Generates screenshots for the docs site using Playwright inside Docker.
|
|
|
|
## Prerequisites
|
|
|
|
- Docker
|
|
- agentsview source at `~/code/agentsview` (override with `AGENTSVIEW_SRC`)
|
|
- A sessions database at `~/.agentsview/sessions.db` (override with `SOURCE_DB`)
|
|
- The screenshot extractor keeps approved public projects from the newest 60-day
|
|
session window (override with `SCREENSHOT_HISTORY_DAYS`)
|
|
- Optional local-only screenshot scrub terms via line-separated files. The
|
|
extractor redacts the current `HOME` path to `~`. By default it also reads
|
|
both `~/.config/agentsview-docs/screenshot-blocked-terms.txt` and the
|
|
canonical private terms file at `~/.config/kenn/private-terms.txt` (or
|
|
`KENN_PRIVATE_TERMS_FILE`). Override the screenshot-specific path with
|
|
`SCREENSHOT_BLOCKED_TERMS_FILE`, or append terms with
|
|
`SCREENSHOT_BLOCKED_TERMS`.
|
|
|
|
## Run all screenshots
|
|
|
|
```bash
|
|
./screenshots/run.sh
|
|
```
|
|
|
|
Output goes to `docs/assets/generated/screenshots/`.
|
|
|
|
## Run a single screenshot
|
|
|
|
Pass `--grep` with the test name:
|
|
|
|
```bash
|
|
./screenshots/run.sh --grep "session filters active"
|
|
```
|
|
|
|
Any extra arguments are forwarded to `npx playwright test` inside the container.
|
|
|
|
## How it works
|
|
|
|
1. Assembles a Docker build context with the agentsview source, sessions
|
|
database, and test files
|
|
1. Builds a multi-stage Docker image:
|
|
- **Stage 1 (builder):** Compiles the agentsview Go binary with frontend
|
|
assets
|
|
- **Stage 2 (db):** Extracts a reduced database with screenshot-safe projects
|
|
- **Stage 3 (playwright):** Installs Playwright + Chromium + PostgreSQL,
|
|
copies binary and DB
|
|
1. Runs the container, which:
|
|
- Starts PostgreSQL and pushes test data from two simulated machines
|
|
- Starts agentsview on port 8090 (SQLite mode, for most screenshots)
|
|
- Starts agentsview pg serve on port 8091 (PG mode, for machine label
|
|
screenshots)
|
|
- Executes the Playwright tests against both servers
|
|
1. Screenshots are written to the mounted `/output` volume
|
|
(`docs/assets/generated/screenshots/`)
|
|
|
|
Stages 1 and 2 are cached by Docker, so re-runs after test file changes are
|
|
fast.
|
|
|
|
## Configuration
|
|
|
|
Viewport: 1440x900, dark mode, `America/Chicago` timezone. See
|
|
`playwright.config.ts`.
|
|
|
|
## Test file
|
|
|
|
All tests live in `tests/screenshots.spec.ts`. Each test navigates to a UI state
|
|
and calls `snap(page, 'name')` or `snapEl(locator, 'name')` to capture a PNG.
