# JerapahFlow
|
||
|
||
|
||
|
||
Workflow runner with a sandboxed script engine, SQLite run history, and an admin UI.
|
||
|
||
## Packages
|
||
|
||
- `@jerapah-flow/server` (`packages/server`) — Fastify runner, HTTP/cron triggers, admin REST API
|
||
- `@jerapah-flow/web` (`packages/web`) — React admin UI (Vite, DaisyUI, React Query)
|
||
|
||
## Setup
|
||
|
||
```bash
|
||
pnpm install
|
||
pnpm dev
|
||
```
|
||
|
||
- API: http://localhost:8700
|
||
- UI (dev): http://localhost:5173
|
||
|
||
The first account created becomes **admin**. Later accounts are created from Users.
|
||
|
||
## Script contract
|
||
|
||
Each script is `async function main(ctx)` and **must** return:
|
||
|
||
```js
|
||
{ output, context?, skipRemaining? }
|
||
```
|
||
|
||
| Field | Meaning |
|
||
|---|---|
|
||
| `ctx.data` | This step’s input (trigger payload, previous `output`, or DAG `needs`) |
|
||
| `ctx.context` | Run clipboard (plain object, default `{}`) |
|
||
| `ctx.config` | This step’s YAML config |
|
||
| `output` | Becomes the **next** step’s `data` |
|
||
| `context` | Next snapshot of the bag. Omitted → keep incoming |
|
||
| `skipRemaining` | Stop later steps. Sibling of `output`/`context`, not inside `output` |
|
||
|
||
Returning the full `ctx` is an error. Mutating `ctx.data` or `ctx.context` does not persist unless returned.
|
||
|
||
YAML **SET** evaluates JSONata against the full `ctx`; the result is `output` (the next step’s data). `jsonata.js` does the same.
|
||
|
||
DAG `needs` assemble this step’s `data` from upstream **outputs**. Independent steps in the same wave share a context snapshot; sibling writes to the same context key fail the run.
|
||
|
||
Optional `script.meta.reads = "ctx"` documents expression hosts. `meta.input` / `meta.output` / `meta.context` describe `data`, the return pipe, and clipboard keys.
|
||
|
||
## Scripts
|
||
|
||
| Command | Description |
|
||
|---|---|
|
||
| `pnpm dev` | Server + Vite together |
|
||
| `pnpm dev:server` | API/runner only |
|
||
| `pnpm dev:web` | UI only (proxies `/api` to :8700) |
|
||
| `pnpm build` | Production UI build |
|
||
| `pnpm start` | Serve API and built UI from :8700 |
|
||
| `pnpm migrate` | Apply SQLite migrations |
|
||
|
||
## Environment
|
||
|
||
| Variable | Default | Notes |
|
||
|---|---|---|
|
||
| `JFLOW_JWT_SECRET` | `jflow-dev-secret` (dev only) | **Required in production**. |
|
||
| `JFLOW_SECRETS_KEY` | `jflow-dev-secrets-key` (dev only) | Master key for named secrets. **Required in production**. Changing it makes existing secrets unreadable. 64 hex chars are used as a raw AES-256 key; any other string is derived with scrypt. |
|
||
| `JFLOW_DB_PATH` | `packages/server/data/jerapah-flow.db` | SQLite file. |
|
||
| `JFLOW_LOG_LEVEL` | `debug` | Pino level |
|
||
| `JFLOW_RETENTION_DAYS` | `30` | Run history prune |
|
||
| `JFLOW_CORS_ORIGIN` | `http://localhost:5173` | Vite origin in dev |
|
||
| `PORT` | `8700` | HTTP port |
|
||
| `NODE_ENV` | — | Set `production` for secure cookies |
|
||
|
||
## Production
|
||
|
||
```bash
|
||
pnpm install
|
||
pnpm build
|
||
JFLOW_JWT_SECRET=... JFLOW_SECRETS_KEY=... NODE_ENV=production pnpm start
|
||
```
|
||
|
||
The server serves `packages/web/dist` when that folder exists.
