- Update artifact generator schemas: - Clarify `path` is the artifact file path relative to the current working directory - Clarify `name` is the artifact symbol name - Remove prompt for `name` and remove it from the important options (won't be displayed by default in Nx Console generation UI, it will be part of the collapsed options) given that most of the time, it's meant to match the filename (last segment of the `path`) - Remove some leftover options related to the name and path formats that were previously missed - Fix an issue with NestJS generators - Fix an issue with Next `page` generator <!-- Please make sure you have read the submission guidelines before posting an PR --> <!-- https://github.com/nrwl/nx/blob/master/CONTRIBUTING.md#-submitting-a-pr --> <!-- Please make sure that your commit message follows our format --> <!-- Example: `fix(nx): must begin with lowercase` --> <!-- If this is a particularly complex change or feature addition, you can request a dedicated Nx release for this pull request branch.

# Add a New Lit Project
|
|
|
|
The code for this example is available on GitHub:
|
|
|
|
{% github-repository url="https://github.com/nrwl/nx-recipes/tree/main/lit" /%}
|
|
|
|
**Supported Features**
|
|
|
|
Because we are not using an Nx plugin for Lit, there are few items we'll have to configure manually. We'll have to configure our own build system. There are no pre-created Lit-specific code generators. And we'll have to take care of updating any framework dependencies as needed.

## Install Lit and Other Dependencies
|
|
|
|
Install all the dependencies we need:
|
|
|
|
{% tabs %}
|
|
{%tab label="npm"%}
|
|
|
|
```shell {% skipRescope=true %}
|
|
nx add @nx/node
|
|
npm add -D lit http-server
|
|
```
|
|
|
|
{% /tab %}
|
|
{%tab label="yarn"%}
|
|
|
|
```shell {% skipRescope=true %}
|
|
nx add @nx/node
|
|
yarn add -D lit http-server
|
|
```
|
|
|
|
{% /tab %}
|
|
{%tab label="pnpm"%}
|
|
|
|
```shell {% skipRescope=true %}
|
|
nx add @nx/node
|
|
pnpm add -D lit http-server
|
|
```
|
|
|
|
{% /tab %}
|
|
|
|
{% tab label="bun" %}
|
|
|
|
```shell
|
|
nx add @nx/node
|
|
bun add -D lit http-server
|
|
```
|
|
|
|
{% /tab %}
|
|
{% /tabs %}
|
|
|
|
## Create an Application
|
|
|
|
We'll start with a node application and then tweak the settings to match what we need. Add a new node application to your workspace with the following command:
|
|
|
|
```shell
|
|
nx g @nx/node:app apps/my-lit-app
|
|
```
|
|
|
|
Choose `none` for the node framework, since we won't be using this as a node app.
|
|
|
|
### Turn the Application into a Lit Application
|
|
|
|
Update `main.ts`:
|
|
|
|
```typescript {% fileName="apps/my-lit-app/src/main.ts" %}
|
|
import { LitElement, html } from 'lit';
|
|
import { customElement, property } from 'lit/decorators.js';
|
|
|
|
@customElement('my-element')
|
|
export class MyElement extends LitElement {
|
|
@property()
|
|
version = 'STARTING';
|
|
|
|
render() {
|
|
return html`
|
|
<p>Welcome to the Lit tutorial!</p>
|
|
<p>This is the ${this.version} code.</p>
|
|
`;
|
|
}
|
|
}
|
|
```
|
|
|
|
Create `index.html`:
|
|
|
|
```html {% fileName="apps/my-lit-app/index.html" %}
|
|
<!DOCTYPE html>
|
|
<html>
|
|
<head>
|
|
<script type="module" src="main.js"></script>
|
|
<style>
|
|
body {
|
|
font-family: 'Open Sans', sans-serif;
|
|
font-size: 1.5em;
|
|
padding-left: 0.5em;
|
|
}
|
|
</style>
|
|
</head>
|
|
<body>
|
|
<my-element></my-element>
|
|
</body>
|
|
</html>
|
|
```
|
|
|
|
### Update the Build Task
|
|
|
|
In the `project.json` file update the `options` under the `build` target. The properties that need to change are `format`, `bundle`, `thirdParty`, and `assets`:
|
|
|
|
```json {% fileName="apps/my-lit-app/project.json" %}
|
|
{
|
|
"targets": {
|
|
"build": {
|
|
"executor": "@nx/esbuild:esbuild",
|
|
"outputs": ["{options.outputPath}"],
|
|
"defaultConfiguration": "production",
|
|
"options": {
|
|
"outputPath": "dist/apps/my-lit-app",
|
|
"format": ["esm"],
|
|
"bundle": true,
|
|
"thirdParty": true,
|
|
"main": "apps/my-lit-app/src/main.ts",
|
|
"tsConfig": "apps/my-lit-app/tsconfig.app.json",
|
|
"assets": ["apps/my-lit-app/src/assets", "apps/my-lit-app/index.html"],
|
|
"generatePackageJson": true,
|
|
"esbuildOptions": {
|
|
"sourcemap": true,
|
|
"outExtension": {
|
|
".js": ".js"
|
|
}
|
|
}
|
|
}
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
Now, when you run the build, there should be `index.html`, `main.js` and `package.json` under `dist/apps/my-lit-app`. Try it out:
|
|
|
|
```shell
|
|
nx build my-lit-app
|
|
```
|
|
|
|
### Update the Serve Task
|
|
|
|
To serve the app, we'll completely overwrite the existing `serve` task. Change it to this:
|
|
|
|
```json {% fileName="apps/my-lit-app/project.json" %}
|
|
{
|
|
"targets": {
|
|
"serve": {
|
|
"dependsOn": ["build"],
|
|
"executor": "nx:run-commands",
|
|
"options": {
|
|
"commands": [
|
|
"http-server dist/apps/my-lit-app",
|
|
"nx watch --projects=my-lit-app --includeDependentProjects -- nx build my-lit-app"
|
|
]
|
|
}
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
`"dependsOn": ["build"]` will ensure that the `build` task is always run before the `serve` task. The entries under `commands` will each be run in parallel. The `http-server` line serves the `build` output with a simple server. The `nx watch` line will automatically re-run the `build` task any time the application code or any project it depends on changes.
|
|
|
|
Run the `serve` task and see your Lit app in action:
|
|
|
|
```shell
|
|
nx serve my-lit-app
|
|
```
|
|
|
|
## Create a Library
|
|
|
|
Let's create a library that our Lit application is going to consume. To create a new library, install the `@nx/js` package and run:
|
|
|
|
```shell
|
|
nx g @nx/js:lib libs/my-lib
|
|
```
|
|
|
|
Once the library is created, update the following files.
|
|
|
|
```typescript {% fileName="libs/my-lib/src/lib/my-lib.ts" %}
|
|
export function someFunction(): string {
|
|
return 'some function';
|
|
}
|
|
```
|
|
|
|
```typescript {% fileName="apps/my-lit-app/src/main.ts" %}
|
|
import { LitElement, html } from 'lit';
|
|
import { customElement, property } from 'lit/decorators.js';
|
|
import { someFunction } from '@my-org/my-lib';
|
|
|
|
@customElement('my-element')
|
|
export class MyElement extends LitElement {
|
|
@property()
|
|
version = 'STARTING';
|
|
|
|
render() {
|
|
return html`
|
|
<p>Welcome to the Lit tutorial!</p>
|
|
<p>This is the ${this.version} code.</p>
|
|
<p>Imported from a library: ${someFunction()}.</p>
|
|
`;
|
|
}
|
|
}
|
|
```
|
|
|
|
Now when you serve your application, you'll see the content from the library being displayed.
