posthtml-img-autosize
Advanced tools
PostHTML plugin that automatically sets width
and height
of <img>
.
It supports JPG, PNG, GIF, BMP, TIFF, SVG, and WebP.
It autosizes both local and remote images.
By default the plugin will autosize only images with width="auto"
and height="auto"
:
var posthtml = require('posthtml');
posthtml([require('posthtml-img-autosize')()])
.process('<img src="photo.png" width="auto" height="auto"><img src="user.jpg">')
.then(function (result) {
console.log(result.html);
});
// <img src="photo.png" width="111" height="52">
// <img src="user.jpg">
But if you set processEmptySize: true
, the plugin will autosize all images with undefined or empty width
and height
:
posthtml([
require('posthtml-img-autosize')({
root: './', // Path to images base directory (default: './')
processEmptySize: true
})
])
.process('<img src="photo.png" width="auto" height="auto"><img src="user.jpg">')
.then(function (result) {
console.log(result.html);
});
// <img src="photo.png" width="111" height="52">
// <img src="user.jpg" width="100" height="201">
If you use ?..
for image versioning in your HTML you should set questionMarkAsVersion: true
in the config:
posthtml([
require('posthtml-img-autosize')({
questionMarkAsVersion: true
})
])
// The image file has "photo.png" name
.process('<img src="photo.png?v=2" width="auto" height="auto">')
.then(function (result) {
console.log(result.html);
});
// <img src="photo.png?v=2" width="111" height="52">
Without that option the plugin would search for a file with name photo.png?v=2
on your disk.
You can use the usual Promise.catch()
to handle errors:
posthtml([require('posthtml-img-autosize')()])
.process('<img src="notExists.jpg" width="auto" height="auto">')
.then(function (result) {
// ...
})
.catch(function (error) {
console.log(error.message);
});
// ENOENT: no such file or directory, open '/notExists.jpg'
