lord-fakealot


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
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 |

$3

Prints the help info to the CLI

`bash
fakealot -h
`




$3


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"
}
`




$3


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

$3

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 {
/**

export interface ILink {
