adonis-ssg

Adonis Static Site Generation (SSG)

Prerender routes to static HTML for AdonisJS enabling Adonis sites to follow the Jamstack architectural approach.

Install

npm i adonis-ssg
yarn add adonis-ssg
pnpm add adonis-ssg

Features

• Simply adds a node ace prerender:routes command
• Follows a similar prerendering pattern to Astro
• Enables prerendering for dynamic routes
• Mix prerendered and non prerendered
• Application wide prerendering can be defined in one getStaticPaths function

Usage

Create a function getStaticPaths and export it from any file. getStaticPaths will be used to determine what routes will be prerendered and provide parameters for dynamic paths.

// ./start/routes.ts

// Define your routes as you would normally...

// Add
export function getStaticPaths() {
    return {
        // Routes you want prerendered
        // Eg. [/route_pattern]: null for a static route,
        // Eg. [/route_pattern_with_some/:parameter]: async () => { return [array of parameter objects]} for a dynamic route
    },
};

Add the file exporting getStaticPaths to directories in .adonisrc.json under the key ssg

{
  "directories": {
    "ssg": "start/routes"
  }
}

Run node ace configure adonis-ssg to add adonis-ssg commands to .adonisrc.json

It will make the following change.

{
  "commands": ["adonis-ssg/dist/index.cjs"]
}

Finally call prerender:routes. By default this will render your HTML files to the public directory as specified in your .adonisrc.json although you can change this with the --output or -o flag.

node ace prerender:routes

Examples

Example prerendered "home", "todo" and "todos/:id" pages with a dynamic "about" page.

// ./start/routes.ts
import Route from "@ioc:Adonis/Core/Route";
import Todo from "./app/Models/Todo";

Route.get("/", async ({ view }) => {
  return view.render("home");
});

Route.get("/about", async ({ view }) => {
  return view.render("about");
});

Route.get("todos", "TodosController.getAll");
Route.get("todos/:id", "TodosController.getById");

export function getStaticPaths() {
  return {
    "/": null,
    "/todos": null,
    "/todos/:id": async () => {
      const todos = await Todo.all();
      return todos.map((todo) => ({
        params: {
          id: todo.id,
        },
      }));
    },
    // We ignore "/about" because we dont want to prerender it
  };
}

Add prerender to build command to package.json

{
  "scripts": {
    "build": "node ace prerender:routes && node ace build --production"
  }
}
