Heroku Buildpack: Nginx for static sites

Operates as an HTTP server for websites and single page apps.

Usage

1. Add Buildpack

Add this buildpack branch to an app, as the last buildpack:

heroku buildpacks:add --app APP_NAME heroku-community/nginx

2. Create Procfile

Create the Procfile in the root of your app, containing,

web: bin/start-nginx-static

3. Create config file

1. Copy the static config into your app as config/nginx.conf.erb.
2. Set the document root for your app (default is /app/dist, this varies by framework/build system).

Migrating from heroku-buildpack-static

To extract the Nginx config from a prior static.json app, see heroku-buildpack-static transition guide.

Configuration

Everything is set-up in config/nginx.conf.erb.

See nginx docs to further customize.

Logging

Sends error & access loglines directly into logplex, for combined logging in the Heroku app.

HTTPS Only

Forces secure HTTP for all requests, by sending 301 redirect responses from http to https.

Document root

The default server document root is /app/dist.

To change it, edit the existing root entry.

Clean URLs

Honor requests for static files without their file extension.

Enable the sample try_files directive:

try_files $uri $uri/ $uri.html =404;

Client-side routing

Respond with index.html for all unknown request paths, so that the client-side app may perform its own routing.

Enable the sample error_page directive:

error_page 404 = /index.html;

Specific behaviors for sub-directories, other locations

Nginx supports overriding the top-level / server configuration with more specific blocks, such as for the sample assets caching rules:

location /assets {
	expires 7d;
}

Custom error pages

Unique error pages for your app may be set, such as sample:

error_page 404 /404.html;

Canonical host

Support for redirecting visitors to a standardized hostname, such as the sample:

server { 
	server_name some-other-name.example.com;
	return 301 https://canonical-name.example.com$request_uri;
}
