How can I serve static web site from s3 through node expressjs?
I wouldn't reinvent the wheel. There's a reasonably recent and well documented middleware module for this on npm
From the docs:
app.get('/media/*', s3Proxy({ bucket: 'bucket_name', prefix: 'optional_s3_path_prefix', accessKeyId: 'aws_access_key_id', secretAccessKey: 'aws_secret_access_key', overrideCacheControl: 'max-age=100000'}));
I wanted /foo to match a /foo.html on a different s3 bucket. I used the following to do so:
app.get('/:thePath', function(req, res) { var key = "saved/" + req.params.thePath; if(key.indexOf(".html") === -1) { key = key + ".html"; } s3.getObject({ Bucket: "just-read", Key: key }) .on('httpHeaders', function (statusCode, headers) { res.set('Content-Length', headers['content-length']); res.set('Content-Type', "text/html"); this.response.httpResponse.createUnbufferedStream() .pipe(res); }) .send();});
