## How to use

### Install

```bash
npm install @lucaselb/node-sp-auth-config --save
```

or install globally to use as CLI:

```bash
npm install @lucaselb/node-sp-auth-config -g
```

### Usage as CLI

```bash
sp-auth init --path ./config/private.config.json
sp-auth --help # for help about parameters
```

### Usage in TypeScript

```javascript
import { AuthConfig } from '@lucaselb/node-sp-auth-config';

const authConfig = new AuthConfig({
  configPath: './config/private.json',
  encryptPassword: true,
  saveConfigOnDisk: true
});

authConfig.getContext()
  .then(context => {
    console.log(JSON.stringify(context, null, 2));
    // context.authOptions - node-sp-auth authentication options
  })
  .catch(console.warn);
```

### Usage in JavaScript

```javascript
const AuthConfig = require('@lucaselb/node-sp-auth-config').AuthConfig;

const authConfig = new AuthConfig({
  configPath: './config/private.json',
  encryptPassword: true,
  saveConfigOnDisk: true
});

authConfig.getContext()
  .then(context => {
    console.log(JSON.stringify(context, null, 2));
    // context.authOptions - node-sp-auth authentication options
  })
  .catch(console.warn);
```

#### Initiation parameters

| Parameter | Default value | Description |
| --- | --- | --- |
| configPath | '`./config/private.json`' | Path to auth config `.json` |
| encryptPassword | `true` | Encrypt password to a machine-bind hash |
| saveConfigOnDisk | `true` | Save config `.json` to disk |
| forcePrompts | `false` | Force parameters prompts |
| headlessMode | `false` | Prevents interactive prompts - for headless, CI/CD processes |
| defaultConfigPath | empty | Path to `.json` config, parameters from which are placed as defaults |
| authOptions | empty | Any valid `node-sp-auth` options |

### Production runtime

#### Headless mode

When using in a headless mode, in case of missing parameters, one can expect non-interactive behavior with no prompts but graceful exit with corresponding error output.

This can be achieved by providing `headlessMode` settings property is equal to `true`.

The headless mode also automatically configured when `NODE_ENV` (or `SPAUTH_ENV`) environment variable is equal to `production`.

#### Environment variables

All the parameters which are usually stored in `private.json` can be defined also using environment variables. Environment variables started with `SPAUTH_` prefix are recognized with the library. Second part of the name is an actual name of the `node-sp-auth` credentials property yet in uppercase (e.g. `SPAUTH_SITEURL`, `SPAUTH_USERNAME`, `SPAUTH_PASSWORD`).

Along with credentials props these service variables are used:

| Variable | Description |
| --- | --- |
| `NODE_ENV` | When equal to `production` forces `headlessMode`. |
| `SPAUTH_ENV` | When equal to `production` forces `headlessMode`. Overwrites `NODE_ENV`. |
| `SPAUTH_FORCE` | Makes `SPAUTH_{CREDENTIALS}` variables take precedence over those possibly stored in `private.json`. |
