# Running Express apps in AWS Lambda
2+
3+
This is a simple example that shows how to deploy an existing [Express](http://expressjs.com/) application, with minimal changes, to AWS Lambda.
4+
5+
## Running the example
6+
7+
1. run `npm install` to grab the dependencies
8+
2. run `npm run generate-proxy` to create a simple proxy API for the express app
9+
3. run `npm run deploy` to send everything up to AWS Lambda
10+
11+
The third step will print out a URL you can use to access the express app.
12+
13+
## Updating the app
14+
15+
1. Change [`app.js`](app.js)
16+
2. (Optionally) use `npm install <PACKAGE NAME> -S` to install additional dependencies (always save them to `package.json` using `-S`)
17+
3. Run `npm run update` to send the new version up to AWS. No need to generate the proxy again
18+
19+
## More information and limitations
20+
21+
See the [Running Express Apps in AWS Lambda](https://claudiajs.com/tutorials/serverless-express.html) tutorial.
