# 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:

```bash
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):

```bash
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)

```bash
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:

```bash
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

```bash
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

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

## Links

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

```bash
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):

```bash
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.
