Usage

Cloudflare Worker Application

Generating a new Cloudflare Worker Application

nx g @naxodev/nx-cloudflare:application my-worker-app

Available options:

Option	Type	Default	Description
name	string	*required	What name would you like to use?
template	fetch-handler, scheduled-handler, hono, none	fetch-handler	Which worker template do you want to use?
projectNameAndRootFormat	as-provided, derived	as-provided	Whether to generate the project name and root directory as provided (`as-provided`) or generate them composing their values and taking the configured layout into account (`derived`).
port	number	8787	The port in which the worker will be run on development mode
accountId	string	null	The Cloudflare account identifier where the worker will be deployed
js	boolean	false	Use JavaScript instead of TypeScript
tags	string	null	Add tags to the application (used for linting).
frontendProject	string	null	Frontend project that needs to access this application. This sets up proxy configuration.
unitTestRunner	vitest, none	vitest	Test runner to use for unit tests.
directory	string	null	The directory of the new application.
rootProject	boolean	false	Create worker application at the root of the workspace
skipFormat	boolean	false	Skip formatting files.

Serve worker on dev mode

nx serve <my-app>

The available options are the following:

Option	Type	Default	Description
script	string	-	The path to an entry point for your Worker.
name	string	-	Name of the Worker.
noBundle	boolean	false	Skip Wrangler’s build steps and show a preview of the script without modification. Particularly useful when using custom builds.
env	string	-	Perform on a specific environment.
compatibilityDate	string	-	A date in the form yyyy-mm-dd, which will be used to determine which version of the Workers runtime is used.
compatibilityFlags, compatibilityFlag	string[]	-	Flags to use for compatibility checks.
latest	boolean	true	Use the latest version of the Workers runtime.
ip	string	-	IP address to listen on, defaults to "localhost."
port	number	-	Port to listen on.
inspectorPort	number	-	Port for devtools to connect to.
routes, route	string[]	-	Routes to upload. For example: --route example.com/*.
host	string	-	Host to forward requests to, defaults to the zone of the project.
localProtocol	"http" or "https"	"http"	Protocol to listen to requests on.
localUpstream	string	-	Host to act as origin in local mode, defaults to dev.host or route.
assets	string	-	Root folder of static assets to be served. Unlike --site, --assets does not require a Worker script to serve your assets. Use in combination with --name and --latest for basic static file hosting. For example: wrangler dev --name personal_blog --assets dist/ --latest.
site	string	-	Root folder of static assets for Workers Sites.
siteInclude	string[]	-	Array of .gitignore-style patterns that match file or directory names from the sites directory. Only matched items will be uploaded.
siteExclude	string[]	-	Array of .gitignore-style patterns that match file or directory names from the sites directory. Matched items will not be uploaded.
upstreamProtocol	"http" or "https"	"https"	Protocol to forward requests to host on.
var	key:value[]	-	Array of key:value pairs to inject as variables into your code. The value will always be passed as a string to your Worker. For example, --var git_hash:$(git rev-parse HEAD) test:123 makes the git_hash and test variables available in your Worker’s env. This flag is an alternative to defining vars in your wrangler.toml. If defined in both places, this flag’s values will be used.
define	key:value[]	-	Array of key:value pairs to replace global identifiers in your code. For example, --define GIT_HASH:$(git rev-parse HEAD) will replace all uses of GIT_HASH with the actual value at build time. This flag is an alternative to defining define in your wrangler.toml. If defined in both places, this flag’s values will be used.
tsconfig	string	-	Path to a custom tsconfig.json file.
minify	boolean	-	Minify the script.
nodeCompat	boolean	-	Enable node.js compatibility.
persistTo	string	-	Specify directory to use for local persistence.
remote	boolean	false	Develop against remote resources and data stored on Cloudflare’s network.
testScheduled	boolean	false	Exposes a /scheduled fetch route which will trigger a scheduled event (cron trigger) for testing during development. To simulate different cron patterns, a cron query parameter can be passed in: /scheduled?cron=++++*.
logLevel	"debug," "info," "log," "warn," "error," "none"	"log"	Specify Wrangler’s logging level.

Deploy worker to Cloudflare

nx deploy <my-app>

The available options are the following:

Option	Type	Default	Description
name	string	-	Name of the Worker.
noBundle	boolean	false	Skip Wrangler’s build steps and directly deploy script without modification. Particularly useful when using custom builds.
env	string	-	Perform on a specific environment.
outdir	string	-	Path to directory where Wrangler will write the bundled Worker files.
compatibilityDate	string	-	A date in the form yyyy-mm-dd, which will be used to determine which version of the Workers runtime is used.
compatibilityFlags	string[]	-	Flags to use for compatibility checks.
latest	boolean	true	Use the latest version of the Workers runtime.
assets	string	-	Root folder of static assets to be served. Unlike --site, --assets does not require a Worker script to serve your assets.
site	string	-	Root folder of static assets for Workers Sites.
siteInclude	string[]	-	Array of .gitignore-style patterns that match file or directory names from the sites directory. Only matched items will be uploaded.
siteExclude	string[]	-	Array of .gitignore-style patterns that match file or directory names from the sites directory. Matched items will not be uploaded.
var	string[]	-	Array of key:value pairs to inject as variables into your code. The value will always be passed as a string to your Worker.
define	string[]	-	Array of key:value pairs to replace global identifiers in your code.
triggers	string[]	-	Cron schedules to attach to the deployed Worker. Refer to Cron Trigger Examples.
routes	string[]	-	Routes where this Worker will be deployed.
tsconfig	string	-	Path to a custom tsconfig.json file.
minify	boolean	-	Minify the bundled script before deploying.
nodeCompat	boolean	-	Enable node.js compatibility.
dryRun	boolean	false	Compile a project without actually deploying to live servers. Combined with --outdir, this is also useful for testing the output of npx wrangler deploy. It also gives developers a chance to upload our generated sourcemap to a service like Sentry, so that errors from the Worker can be mapped against source code, but before the service goes live.
keepVars	boolean	false	It is recommended best practice to treat your Wrangler developer environment as a source of truth for your Worker configuration, and avoid making changes via the Cloudflare dashboard. If you change your environment variables or bindings in the Cloudflare dashboard, Wrangler will override them the next time you deploy. If you want to disable this behavior set keepVars to true.

Cloudflare Worker Library

Generating a new Cloudflare Worker Library

nx g @naxodev/nx-cloudflare:library my-worker-lib

Available options:

Option	Type	Default	Description
name	string	*required	What name would you like to use?
directory	string	null	The directory of the new application.
projectNameAndRootFormat	as-provided, derived	as-provided	Whether to generate the project name and root directory as provided (`as-provided`) or generate them composing their values and taking the configured layout into account (`derived`).
linter	eslint, none	eslint	The tool to use for running lint checks.
unitTestRunner	vitest, none	vitest	Test runner to use for unit tests.
tags	string	null	Add tags to the application (used for linting).
skipFormat	boolean	false	Skip formatting files.
js	boolean	false	Use JavaScript instead of TypeScript
strict	boolean	true	Whether to enable tsconfig strict mode or not.
publishable	boolean	false	Generate a publishable library.
importPath	string	null	The library name used to import it, like @myorg/my-awesome-lib. Required for publishable library.
bundler	swc, tsc, rollup, vite, esbuild, none	tsc	Which bundler would you like to use to build the library? Choose 'none' to skip build setup.
minimal	boolean	false	Generate a library with a minimal setup. No README.md generated.
simpleName	boolean	false	Don't include the directory in the generated file name.

NextJS on Cloudflare

Build Next application.

This feature is ⚠️ experimental. We appreciate that you let us know of any issues that you find.

To start using the Cloudflare Pages Next builder, start by replacing the builder executor in your application project.json.

  ...
  "targets": {
    ...
    "build": {
      "executor": "@naxodev/nx-cloudflare:next-build",
      ...
    },
    ...

Notice that you can use the same configurations as in the @nx/next:build executor.

Now you can run the build command.

nx build <app-name>

And upload the content of the folder .vercel/output/static contained in the folder matching your configured output path.

Acknowledgement

This project is heavily inspired in the work done by other Nx Champions, check out their projects.
