Module svelte-ast-print

Example: Recommended usage

If you know which specific AST node from Svelte syntax you want to print.
There are 4 categories of AST nodes available and their respective submodules:

• CSS - "svelte-ast-print/css"
• HTML - "svelte-ast-print/html"
• JavaScript & TypeScript - "svelte-ast-print/js"
• Svelte template - "svelte-ast-print/template"

Let's take for example SV.SnippetBlock which is a Svelte template-related node.

import type { AST } from "svelte/compiler";
import { printSnippetBlock } from "svelte-ast-print/template/block";

// How you obtain the node is up to you.
// Either by building programmatically or from parsing
let node: AST.SnippetBlock;

const stringified = printSnippetBlock(node);
Copy

Example: General usage

If you don't know which AST node from Svelte syntax you want to print. It could be either JavaScript/TypeScript (ESTree specification complaint) or Svelte. Under the hood it uses esrap#print.

import type * as JS from "estree";
import type { AST as SV } from "svelte/compiler";
import { print } from "svelte-ast-print";

// How you obtain the node is up to you.
// Either by building programmatically or from parsing
let node: JS.Node | SV.BaseNode;

const stringified = print(node);
Copy

Example: General usage - Svelte only

If you don't know which AST node from Svelte syntax you want to print, but you know that it's Svelte.

import type { AST } from "svelte/compiler";
import { printSvelte } from "svelte-ast-print";

// How you obtain the node is up to you.
// Either by building programmatically or from parsing
let node: AST.BaseNode;

const stringified = printSvelte(node);
Copy

Options

Every print* function accepts a second argument for options. Is optional and has some sensible defaults.
