# lord-fakealot

[![Codacy Badge](https://api.codacy.com/project/badge/Grade/a6989f4384e0440394870f22ad1c0f8f)](https://app.codacy.com/app/faebeee/lord-fakealot?utm_source=github.com&utm_medium=referral&utm_content=faebeee/lord-fakealot&utm_campaign=Badge_Grade_Dashboard)

`lord-fakealot` is a utility to generate mocked data based on typescript interfaces.
It loads all interfaces from a given directory and can either expose an HTTP api or
generate `json` files with mocked data in it

## Install
`npm i -g lord-fakealot`
This will then expose `fakealot` as a CLI entrypoint for this app

## Data population
Under the hood, `lord-fakealot` uses faker. You can use any [faker API Method](https://github.com/marak/Faker.js/#api-methods)
in your annotations by writing `@faker `.

__Example__
```typescript
export interface FakerInterface {
/**
* @faker lorem.word
*/
word: string;

/**
* @faker lorem.paragraphs
*/
paragraphs: string;

/**
* @faker finance.amount
*/
finance: string;

}
```

## Commands

|command | description |
|---|---|
|help | prints the help text|
|api| exposes an HTTP API on a given port|
|file| generate a file containing all populated interfaces|
|files| generating a folder, containing JSON a json file for each interface |

### `help`
Prints the help info to the CLI

```bash
fakealot -h
```

### `files`
This commands create a jsonfile for every interface found in the `dir` directory. The name of each file
is the interfacename.

```bash
fakealot files --out ./out --dir ./test [--tsconfig ./tsconfig.json]
```

#### Options

| Name | Type | Description |
|---|---|---|
| --dir | string | Directory path where all the interfaces are stored in. Dir will be searched recursive|
| --out | string | Folder where all files will be created |
| --tsconfig | string - optional | Path to the tsconfig file

Create a directory `out` with files in it.
Each file then contains directly the interface data like this:

__ComplexInterface.ts__
```typescript
export default interface ComplexInterface {
type: string;

/**
* @minimum 2
* @maximum 2
*/
items: IItem[];

}

export interface IItem {
name: string;

/**
* @minimum 0
* @type integer
*/
position: number;
}
```

___ComplexInterface.json___
```json
{
"items": [
{
"name": "dolore in qui et",
"position": 70112329
},
{
"name": "tempor anim irure laborum",
"position": 77636896
}
],
"type": "aute dolor id enim culpa"
}
```

### `file`
The `file` command will create a file, which stores a a collection with fake data for all interfaces found in the `dir`

The command

```bash
fakealot file --file ./mock.json --dir ./interfaces --tsconfig ./tsconfig.json
```

#### Options

| Name | Type |Description |
|---|---|---|
| --dir | string | Directory path where all the interfaces are stored in. Dir will be searched recursive|
| --file | string | Path to file where the data will be dumped |
| --tsconfig | string - optional | Path to the tsconfig file

will create a new file name `mock.json`

with the content

```json

},
"MultiFileInterface": {

}
}
```

### `api`
This command creates a server which then can be accessed from you App. By passing the interface name to the route,
data with the same structure as the interface is served.

```bash
fakealot api --port 3000 --dir ./SRC --tsconfig ./tsconfig.json
```
now by visting `http://localhost:3000/api/schema/{INTERFACENAME}` you'll get some mocked data.

#### Options

| Name | Type |Description |
|---|---|---|
| --dir | string | Directory path where all the interfaces are stored in. Dir will be searched recursive|
| --port | number | Port number
| --tsconfig | string - optional | Path to the tsconfig file

__Interface__
```typescript
export default interface LangSwitch {
/**
* Type definition
* @faker lorem.paragraph
*/
type: string;

/**
* Type definition
* @pattern yes|no
*/
isActive: string;

languages: ILink[];
}

export interface ILink {
path: string;
label: string;
external?: boolean;
icon?: IIcon;
}

export interface IIcon {
