Big file loader in chunks for browser
Installing
Package is available in npm. It's in cjs,es and iife format so it will work correctly with all popular bundlers(webpack) and also nodejs.
npm install readery --save
Using yarn
yarn add readery --save
For direct usage without bundler, use iife format and import file directly:
<script src="dist/readery.iife.min.js"></script>
API
import {readFromFile} from "readery"
readFromFile(readFromFile(
file,
dataCb,
loadingProgressCb = progress => {},
finishedCb = () => {},
config = { splitBy: /\r?\n/, encoding: "UTF-8" },
chunkSize = 256 * 1024
)
If splitBy is undefined then there is no splitting.
Example usage
<body>
<input type="file" id="file-input" name="file" />
<script>
function handleFileSelect(evt) {
var file = evt.target.files[0];
readery.readFromFile(file, d => {
console.log("Chunk = ", d);
},
p => { console.log("Progress: " + p) },
() => { console.log("finished")
});
}
document.getElementById('file-input').addEventListener('change', handleFileSelect, false);
</script>
</body>
