Is there a way to prevent Faker from continuously displaying the identical picture?

One of the challenges I'm facing involves using faker to generate an array of random objects. Here's a snippet of what I have:

{
  "image":  faker.random.arrayElement([
    faker.image.nature(), 
    faker.image.city(), 
    faker.image.food() 
  ]),
  "price": faker.random.number({ min: 20, max: 300 }),
  "beds": faker.random.number({ min: 1, max: 15 }),
  "type": faker.random.arrayElement([ 
    "Entire home", 
    "Private room", 
    "Shared room" 
  ])
}

However, while all the data is randomized with each load, the image remains the same for every element in the array.

Although different photos appear upon refreshing the page, the images for all elements within the array remain identical.

Any suggestions on how to resolve this issue?

Answer №1

It is important to note that faker.js consistently returns the same URL, such as

http://lorempixel.com/640/480/nature
, for every faker.image.nature() function call due to the random image generation service provided by lorempixel.com.

If you are concerned about getting identical images each time, this issue could be linked to your browser caching responses. To address this, consider disabling caching while in development or appending a unique query string to the image URL like so:

'image': `${faker.image.nature()}?random=${Date.now()}`
.

In short, you do not need to take any specific actions. The random images will eventually be displayed when requested from lorempixel.com.

Answer №2

Was on the hunt for the same information and stumbled upon this gem in the documentation.

faker.image.nature(width, height, randomize)
Parameters
| Name       | Type  | Default |
|------------|-------|---------|
| width?     |number |  640    |
| height?    |number |  480    |
| randomize? |boolean|  false  |
