## What it does

This skill guides your coding agent through the `@sasjs/adapter` library for TypeScript and Node.js projects. It explains how to set up the `SASjs` instance, pass arguments to `sasjs.request()`, and handle server targets like `SAS9`, `SASVIYA`, or `SASJS`.

The `data` parameter accepts flat tables instead of arbitrary JSON trees. Each object key represents a dataset inside the SAS `work` library. Table names must start with a letter or underscore and stay within 32 characters. Rows cannot contain undefined properties. If payload strings exceed 500000 characters or contain semicolons, the adapter switches transport to multipart CSV file uploads.

Backend outputs return lowercase table keys, whereas column names arrive in uppercase. To capture execution logs alongside the JSON payload, you must include `['log']` inside `extraResponseAttributes`.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add sasjs/skills --skill sasjs-adapter -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-adapter/SKILL.md

## When to use it
- Configure a `SASjs` client for SAS9, SAS Viya, or SASjs targets
- Structure tabular payloads into valid SAS `work` datasets
- Handle `_webout` responses with lowercase tables and uppercase columns
- Extract execution logs via `extraResponseAttributes` during debugging

## Example prompts
- Configure a SASjs client for SASVIYA and request services/common/getdata with a customers table.
- Why is sasjs.request rejecting my data object during table validation?
- Show how to call sasjs.request with extraResponseAttributes set to log.

# @sasjs/adapter

`@sasjs/adapter` is the TypeScript library for calling SAS services/jobs from browsers or Node, with a unified API across three server types: `SAS9`, `SASVIYA`, `SASJS`.

## Basic setup

```ts
import SASjs from '@sasjs/adapter'

const sasjs = new SASjs({
  serverUrl: 'https://sas.example.com',
  serverType: 'SASVIYA',      // SAS9 | SASVIYA | SASJS
  appLoc: '/Public/app/myapp', // root folder of deployed services
  contextName: 'SAS Job Execution compute context', // Viya only
  debug: false
})
```

## request() - inputs (JS -> SAS)

### Signature

```ts
sasjs.request(
  sasJob: string,
  data: { [key: string]: any[] } | null,
  config?: { [key: string]: any },             // merged over SASjsConfig
  loginRequiredCallback?: () => any,
  authConfig?: AuthConfig,                      // Viya tokens for Node usage
  extraResponseAttributes?: ExtraResponseAttributes[]  // ['log'] | ['file'] | ['data']
)
```

- `sasJob`: relative path (no leading slash) resolved against `appLoc`, or an absolute path. Becomes the SAS `_program` parameter.
- `data`: an object whose keys become **work datasets in SAS**. Can be `null` if the service takes no input.
- `config`: overrides merged on top of the constructor config for this call only.

### The `data` object - tables, not arbitrary JSON

Every key in `data` must be an **array of plain objects**. Each key becomes a SAS work dataset named after the key; each object in the array is a row; each property is a column.

```ts
const res = await sasjs.request('services/common/getdata', {
  customers: [
    { id: 1, name: 'Acme', active: true },
    { id: 2, name: 'Globex', active: false }
  ],
  config: [{ rootdir: '/tmp', retries: 3 }]  // even a single-row "config" table
})
```

On the SAS side these arrive as `work.customers` and `work.config`.

### Input validation rules

Before sending, the adapter validates `data` (see `validateInput`). Violations reject the promise with an `ErrorResponse`:

- `data` must be `null` or a plain object (not an array, not a primitive).
- Every table key must start with a letter or underscore: `/^[a-zA-Z_][a-zA-Z0-9_]*$/`. Numbers at the start are rejected.
- Table names cannot exceed **32 characters** (SAS name limit).
- Every value under a key must be an array of objects. Non-object rows are rejected.
- No property in any row may be `undefined` (it must be `null`, a string, a number, or a boolean).

### How tables are serialized to CSV

Each table is converted to CSV via `convertToCSV`. The conversion is type-aware:

- **String columns**: quoted only if they contain commas, tabs, newlines, or quotes. Internal `"` is escaped as `""`.
