gobl.builder

GOBL Builder is an interactive, low code tool for building GOBL documents.

This repository contains GOBLBuilder, a Svelte component used to render a self-contained UI with menu bar, toolbar, code editor and bottom drawer for showing errors, warnings and more. The component is packaged publically on NPM, to be imported and used from Svelte projects.

A standalone wrapper for GOBLBuilder is included in this repository in src (not part of the packaged library). It's available at https://build.gobl.org.

Requirements

At the moment, the component library relies on Tailwind CSS for styling. This might change in the future.

Installation

GOBL Builder is released as @invopop/gobl-builder on NPM. To add it to your Svelte project:

npm add -D @invopop/gobl-builder

Assuming your project already is configured to use Tailwind CSS, configure its template paths to include the component library and Flowbite (its dependency). An example tailwind.config.cjs file:

/** @type {import('tailwindcss').Config} */
module.exports = {
  content: ["./src/**/*.{html,js,svelte,ts}", "./node_modules/@invopop/gobl-builder/**/*.{html,js,svelte,ts}"],
  theme: {
    extend: {},
  },
  plugins: [],
};

Usage

Import and use the GOBLBuilder Svelte component. For example, using TypeScript:

<script lang="ts">
  import GOBLBuilder from "@invopop/gobl-builder";
</script>

<GOBLBuilder data="" jsonSchemaURL="https://gobl.org/draft-0/bill/invoice" />

For further example usage, including directives for event handling, see src/routes/+page.svelte.

Development

Below sections cover development of the component library itself. See above sections for instructions on using GOBL Builder in your own project.

Installation

Clone this repository from GitHub, then run from within its directory:

npm install

For an optimal developer experience, use an IDE with plugin support for Svelte, TypeScript, ESLint and Prettier. For VS Code, recommended plugins are included in .vscode/extensions.json.

Run in watch mode

npm run dev

This script uses vite to run a development web server with HMR. It compiles TypeScript to JavaScript and serves the demo wrapper on http://localhost:3000.

Build package

npm run build:package

This script uses svelte-package to build a component library, written to the package directory (ref).

Build standalone demo

npm run build

This uses vite to build and write an optimized for production of the standalone demo to the build directory.

Preview production build

npm run preview

This uses vite to serve a previously built build folder on http://localhost:4173.

GOBL WASM binary

GOBL Builder makes use of gobl cli for validating, calculating and building GOBL documents. This is done using the @invopop/gobl-worker package that prepares a Worker and uses the WASM binary distributed on cdn.gobl.org.

To upgrade the version of the GOBL worker currently in use, simply update the package.json file to reflect the new version.
