filename.jpg?w=1280&h=720
The app will have to The app will have to return an image( filename.jpg
) with the width ( w
) and the height ( h
)
This already works (I use sharp), but I don't know how to get the image scaling information from the URL
This is the code for now
Router file:
export default {
getImage: [
async (req, res, next) => {
try {
const { image, size } = req.params
const path = await generateFile(image, size)
res.sendFile(path)
} catch (err) {
next(err)
}
}
]
}
Controller file:
import sharp from 'sharp'
async function generateFile (image, size) {
const x = options.split('-')[0]
const y = options.split('-')[1]
sharp('./img/' + image)
.resize(x, y)
.toFile(./resized/ + img)
}
Function file:
import sharp from 'sharp' async function generateFile (image, size) { const x = options.split('-')[0] const y = options.split('-')[1] sharp('./img/' + image).resize(x, y).toFile(./resized/ + img) }
Thanks to Heiko Theißen
Use req.query
This is the solution:
getImage: [
async (req, res, next) => {
try {
const { image } = req.params
const path = await generateFile(image, req.query)
res.sendFile(path)
} catch (err) {
next(err)
}
}
]
async function generateFile (image, query) {
const { x, y } = query
sharp('./img/' + image)
.resize(x, y)
.toFile(./resized/ + img)
}
