# Yaak Faker Plugin
This is a template function that generates realistic fake data
for testing and development using [FakerJS](https://fakerjs.dev).
![CleanShot 2024-09-19 at 13 56 33@2x](https://github.com/user-attachments/assets/2f935110-4af2-4236-a50d-18db5454176d)
## Example JSON Body
Here's an example JSON body that uses fake data:
```json
{
"id": "${[ faker.string.uuid() ]}",
"name": "${[ faker.person.fullName() ]}",
"email": "${[ faker.internet.email() ]}",
"phone": "${[ faker.phone.number() ]}",
"address": {
"street": "${[ faker.location.streetAddress() ]}",
"city": "${[ faker.location.city() ]}",
"country": "${[ faker.location.country() ]}",
"zipCode": "${[ faker.location.zipCode() ]}"
},
"company": "${[ faker.company.name() ]}",
"website": "${[ faker.internet.url() ]}"
}
```
This will generate a random JSON body on every request:
```json
{
"id": "589f0aec-7310-4bf2-81c4-0b1bb7f1c3c1",
"name": "Lucy Gottlieb-Weissnat",
"email": "Destiny_Herzog@gmail.com",
"phone": "411.805.2871 x699",
"address": {
"street": "846 Christ Mills",
"city": "Spencerfurt",
"country": "United Kingdom",
"zipCode": "20354"
},
"company": "Emard, Kohler and Rutherford",
"website": "https://watery-detective.org"
}
```
