sethbergman / create-react-app-lambda

This project is based on Create React App. (For more information about Create react App, check their full documentation.)

The main addition is a new folder: src/lambda. Each JavaScript file in there will automatically be prepared for Lambda function deployment.

As an example, we've included a small src/lambda/hello.js function, which will be deployed to /.netlify/functions/hello.

Babel/webpack compilation

All functions are compiled with webpack using the Babel Loader, so you can use modern JavaScript, import npm modules, etc., without any extra setup.

Local Development

Before developing, clone the repository and run yarn from the root of the repo to install all dependencies.

Run the functions dev server

From inside the project folder, run:

yarn start:lambda

This will open a local server running at http://localhost:9000 serving your Lambda functions, updating as you make changes in the src/lambda folder.

You can then access your functions directly at http://localhost:9000/{function_name}, but to access them with the app, you'll need to start the app dev server.

Run the app dev server

While the functions server is still running, open a new terminal tab and run:

yarn start

This will start the normal create-react-app dev server and open your app at http://localhost:3000.

Local in-app requests to the relative path /.netlify/functions/* will automatically be proxied to the local functions dev server.

create-react-app-lambda's Issues

Action required: Greenkeeper could not be activated 🚨

🚨 You need to enable Continuous Integration on all branches of this repository. 🚨

To enable Greenkeeper, you need to make sure that a commit status is reported on all branches. This is required by Greenkeeper because it uses your CI build statuses to figure out when to notify you about breaking changes.

Since we didn’t receive a CI status on the greenkeeper/initial branch, it’s possible that you don’t have CI set up yet. We recommend using Travis CI, but Greenkeeper will work with every other CI service as well.

If you have already set up a CI for this repository, you might need to check how it’s configured. Make sure it is set to run on all new branches. If you don’t want it to run on absolutely every branch, you can whitelist branches starting with greenkeeper/.

Once you have installed and configured CI on this repository correctly, you’ll need to re-trigger Greenkeeper’s initial pull request. To do this, please delete the greenkeeper/initial branch in this repository, and then remove and re-add this repository to the Greenkeeper App’s white list on Github. You'll find this list on your repo or organization’s settings page, under Installed GitHub Apps.
