img-autosize v1.0.0

img-autosize

Read all images in a directory and automatically resize them to various sizes, optimized for http serving.

Installation

npm install -g img-autosize

Usage

img-autosize config.json
img-autosize --watch config.json

Example Config

[{
	"inputDir": "test_input",
	"maxWidth": 400,
	"maxHeight": 400,
	"suffix": "_m",
	"outputDir": "test_output"
}]

How it works

1. read config file which is an array of { inputDir, maxWidth, maxHeight, suffix, outputDir }
2. watch every jpeg, jpg, and png files in inputDir and its descentdant for changes
3. if a new file is added, a resized version of that file with suffix is created to the outputDir.
4. if a file is deleted, all resized version of that file is also deleted.
5. if a file is changed, similar to when a file is created.

• Don't use inputDir and outputDir as the same folder or is a descendant of one another as it can cause infinite loop
• We use chokidar and sharp.
