A asset-pipe sink for writing and reading asset feeds and js/css bundles to and from a simple in memory store.

The intention of the asset-pipe sink modules is to use be able to write and read files to different backends by just swapping modules. By each sink implementing the same public API it is possible to ex use this module in one environment and another sink module in another environment.

These sinks are normally used by the asset-pipe-build-server.

Installation

$ npm install @asset-pipe/sink-mem

Example

Read an asset feed from the store and serve it on http:

const express = require('express');
const Sink = require('@asset-pipe/sink-mem');

const app = express();
const sink = new Sink();

app.get('/', (req, res, next) => {
    const file = sink.reader('feed.json');
    file.on('file not found', () => {
        res.status(404).send('File not found');
    });
    file.on('file found', () => {
        res.status(200);
        file.pipe(res);
    });
});

app.listen(8000);
