Your Name 42f4aacf7c feat: append-only version history + bliss CLI ergonomics
Snapshot the code-bearing fields of routes (verb/path/handler), templates
(name/content/test_object), and db libraries (name/library) on every
content-changing save, so nothing edited is ever lost. Recorded in a new
`versions` table via recordVersion() hooked into the create/update functions
in db.js (the single write choke point), deduped against the latest snapshot
so no-op saves, error-flag-only route writes, and server-restart WS
re-bootstraps don't pile up. The live row stays current; old snapshots are the
undo trail. Read-only, no revert UI yet.

- migrations/004_add_versions.sql: versions table + indexes
- db.js: recordVersion/getVersions/getVersion + create/update hooks
- plumbing.js: /versions/:id and per-entity .../versions list endpoints
- bliss: `versions <type> <sid> <id>` and `version <id>` reads;
  `update-settings` (edit route_prefix/head_injection, preserving the
  untouched field); `use <url>` sticky target persisted to ~/.bliss/target
  so BLISS_URL needn't be re-exported each call
- client.js: target-file precedence (BLISS_URL > ~/.bliss/target > localhost)
- SKILL.md: document the above

name description
bliss Drive a remote Bliss instance from the command line the way a human uses the /workshop UI — create/edit structures, routes, templates, databases, run the db REPL, read logs. Use when asked to build, inspect, or modify Bliss Structures against a running instance.

bliss CLI

bliss talks to a running Bliss instance exactly as a human does through the workshop UI. Reads come back as JSON from the /plumbing API (pipe into jq). Writes go through the same /workshop/* endpoints the UI posts to.

Setup

The CLI is at bliss-cli/bliss in the repo. Configure via env vars:

export BLISS_URL=https://your-instance.example.com   # default http://localhost:3000
export BLISS_USER=you
export BLISS_PASS=secret

It logs in once and caches the session cookie under ~/.bliss/, re-logging-in automatically when it expires. Run it as node bliss-cli/bliss <command> (or ./bliss-cli/bliss if on PATH).

Instead of re-exporting BLISS_URL every time, set a sticky target once — it persists to ~/.bliss/target and is used until you change it (a BLISS_URL env var still overrides it when set):

bliss use https://your-instance.example.com   # set the target instance
bliss use                                      # print the current target

The model (what you're editing)

A Structure is a mini web app. It has routes (a VERB + path + a JS handler string run in a sandbox), templates (Eta, with a test_object used for preview), and databases (each with a library JS module and its own SQLite file). Ids are integers. Build a structure by: create it → add a db → write its library → add routes whose handlers call the library → add templates the handlers render.

Reads (JSON)

bliss structures                       # list all structures
bliss structure <sid>                  # structure + its routes, templates, dbs, files
bliss route <sid> <rid>                # one route incl. its handler source
bliss template <sid> <tid>             # one template incl. content + test_object
bliss db <sid> <dbid>                  # one db incl. its library source
bliss files <sid>                      # files attached to a structure
bliss logs <sid> <rid> [--since <id>]  # route logs (console.log output + errors)

bliss versions <route|template|db> <sid> <id>   # save history (newest first)
bliss version <versionId>                        # one version incl. full snapshot

All emit JSON, so: bliss structure 3 | jq '.routes[].path'.

Version history (undo trail)

Every content-changing save of a route handler, template, or db library records an append-only snapshot. The live row is always the current version; old ones are kept so nothing edited is ever lost. versions lists the summaries (id, created_at, bytes) newest-first; version <id> returns the full snapshot (the versioned fields). No-op re-saves are deduped, so identical content doesn't pile up. There's no revert command yet — to roll back, fetch an old snapshot and re-update-* its content:

bliss versions route 3 12                        # what saves exist
bliss version 24 | jq -r .snapshot.handler > /tmp/old.js
bliss update-route 3 12 --handler-file /tmp/old.js   # restore it as a new save

Writes

bliss create-structure "<name>"                 # -> {location, id}
bliss update-settings <sid> [--route-prefix <p>] [--head-injection <s>|--head-injection-file <f>]
bliss clone <sid> --name "<n>" --prefix /p [--clone-dbs]

bliss create-route <sid> <VERB> <path>          # VERB: GET|POST|PUT|DELETE|WS ; -> {id}
bliss update-route <sid> <rid> --handler-file <f|->   # replace handler code
        [--scaffold-file <f>] [--path <p>] [--verb <v>]

bliss create-template <sid> "<name>"            # -> {id}
bliss update-template <sid> <tid> --content-file <f|-> [--test-object-file <f>]

bliss create-db <sid> "<name>"                  # -> {id}
bliss attach-db <sid> <dbid> <alias>            # share an existing db under an alias
bliss update-library <sid> <dbid> --file <f|->  # returns eval output/errors

bliss repl <sid> <dbid> '<code>'                # run JS/SQL against the db; --file <f|-> also works
bliss upload <sid> <path>                       # upload a static file

Previews

bliss preview-route <sid> <rid>        # rendered HTML of a GET route
bliss preview-template <sid> <tid>     # rendered HTML using the template's test_object

Jump straight into the workshop editor for something instead of constructing the URL by hand:

bliss link structure <sid>
bliss link route <sid> <rid>
bliss link template <sid> <tid>
bliss link db <sid> <dbId>       # by numeric db id
bliss link db <sid> <alias>      # or by the alias used in require('db')(alias)

bliss link db resolves an alias (e.g. chat, as in require('db')('chat')) by looking at the structure's attached dbs — handy since the same alias name often points to a different db per structure (aliased/cloned dbs).

Editing code (handlers, templates, library)

Handlers/templates/library are multiline code. Write the code to a temp file and pass --*-file, or pipe via - (stdin):

cat > /tmp/handler.js <<'EOF'
function handler(req, res) {
  const { library } = require('db')('main');
  res.render('home', { items: library.all() });
}
EOF
bliss update-route 3 12 --handler-file /tmp/handler.js

echo "function handler(req,res){ res.send('hi') }" | bliss update-route 3 12 --handler-file -

The db library runs with sql (the better-sqlite3 instance) in scope and sets module.exports. Test it fast with bliss repl <sid> <dbid> 'library.someFn()'.

Typical loop

  1. bliss structures / bliss structure <sid> to orient.
  2. Edit a handler/template/library into a temp file, push with the matching update-* command.
  3. bliss preview-route / bliss repl to see the result; bliss logs to debug.
