## What it does

The skill spells out what a SASjs app is made of: a web frontend in any framework plus SAS backend code in a standard layout, compiled and deployed by `@sasjs/cli` to SAS 9, Viya or SASjs server. The frontend reaches SAS through `@sasjs/adapter`, and services hand back JSON in `_webout`.

Config work gets most of the space. Root defaults live in `sasjsconfig.json`, and each `targets[]` entry can override them: `serverUrl`, `serverType` (`SAS9`/`SASVIYA`/`SASJS`), `appLoc`, per-target macro folders, `httpsAgentOptions`, `deployConfig`. Folders are declared through `macroFolders`, `binaryFolders`, `serviceConfig.serviceFolders`, `jobConfig.jobFolders`, `programFolders`. With `streamWeb: true` the built frontend is uploaded into SAS itself, so no separate web server is needed; `webSourcePath` points at the build output. The bundled schema is referenced as `"$schema": "https://cli.sasjs.io/sasjsconfig-schema.json"`.

There is a hard rule about the service header. The `@li` lines under `SAS Macros` are a dependency manifest, not comments: any macro the service calls must be listed, or it never gets inlined and the deployed job dies with `Apparent invocation of macro X not resolved`. Editing an existing service means re-auditing every `%macro()` call against that header. Errors are raised with `%mp_abort(...)` using the `iftrue=` parameter rather than inside `%if/%else`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add sasjs/skills --skill sasjs-framework -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/sasjs-framework/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/sasjs-framework/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add sasjs/skills --skill sasjs-framework -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/sasjs-framework/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add sasjs/skills --skill sasjs-framework -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/sasjs-framework/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install sasjs/skills sasjs-framework
```

2. **Manually: put the files in place**
- File: `.github/skills/sasjs-framework/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add sasjs/skills --skill sasjs-framework -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/sasjs/skills --path sasjs-framework
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/sasjs-framework/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add sasjs/skills --skill sasjs-framework -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/sasjs/skills/tree/HEAD/sasjs-framework/SKILL.md

## When to use it
- scaffold a new SASjs project in the standard folder layout
- point one config at SAS 9, Viya and SASjs server
- return JSON from a SAS service to the frontend
- validate request inputs before they reach generated code
- fix a service that fails on an unresolved macro

## Example prompts
- Scaffold a SASjs app and fill in `sasjsconfig.json` for Viya
- Add a service that reads an input table and writes JSON to `_webout`
- Audit the service header: is every called macro declared with `@li`?

# SASjs Framework - Building SASjs Applications

A SASjs app = a web frontend (any framework: Angular, React, vanilla) + SAS backend code organised in a standard layout, compiled and deployed by `@sasjs/cli` to SAS 9, Viya, or SASjs server. Frontend talks to SAS via `@sasjs/adapter`; backend services return JSON via `_webout`.

## Standard project layout

```
sasjs/
  sasjsconfig.json     # project + target configuration
  macros/              # project-specific macros (macroFolders)
  services/            # web services called from the frontend
  jobs/                # jobs (scheduled / flow / long-running)
  programs/            # plain programs (initProgram, termProgram, utilities)
  db/                  # DDL + static data per library (sasjs db)
  tests/               # tests run by `sasjs test`
  mocks/               # mock responses for offline frontend dev (syncFolder)
  doxy/                # extra doxygen content for `sasjs doc`
```

## sasjsconfig.json

Root config holds defaults; each entry in `targets[]` can override them. Key sections:

- `macroFolders`, `binaryFolders` - where the CLI finds macros/binaries
- `serviceConfig.serviceFolders` - service source folders; `initProgram` runs before every service (set up libnames, options)
- `jobConfig.jobFolders` - job source folders
- `programFolders` - programs compiled/deployed with the app
- `streamConfig` - `streamWeb: true` streams the built frontend into SAS so it is served by the platform itself (no separate web server needed); `webSourcePath` points at the frontend build output
- `syncFolder` - folder synced to the server (e.g. mocks)
- `testConfig` - init/term programs for `sasjs test`
- `targets[]` - per-environment overrides: `serverUrl`, `serverType` (`SAS9`/`SASVIYA`/`SASJS`), `appLoc` (deploy root, e.g. `/Public/app/myapp`), target-specific macroFolders (e.g. `targets/viya/macros_viya` for platform shims), `httpsAgentOptions`, `deployConfig`
