I have found weird bug in my application. I am using VueJS3 and typescript. I am creating a media gallery, where users can manage assets. All endpoints and backend side of application works perfectly. Currently i am working on updating image files(updating image field). My code works in theory, image url updates to a new one, but even the url is newer, image that is rendered is old image(before update). When i try to view my application in incognito window, my newer image is showing. But it does not work otherwise(works if and only user clears his cache) I hope i explained myself clearly, it is a little complicated :)
When i fetch the data from api, they don't have any src, so i have to create a property when using the data. Here is the code below.
const { res, err } = await this.$api.image.getAll(params)
res.data.items.forEach(async (image: Image<Populated>) => {
image.src = this.$fileHandler(image._id)
})
Note: File handler is a special method that gives the image source by id
Apparently your assets get cached, and there are multiple ways to solve that.
Not diving too much into caching strategies and cache control tags, just do
image.src = `${this.$fileHandler(image._id)}?_=${+new Date()}`
This will generate a unique (almost) URL for your image, invalidating every previous cached one.
