docx-templates-to-pdf

This is a helper Package on top of docx-templates and gotenberg-js-client to fill docx template Documents with data and convert it into PDF-Files.

Note this is a simple wrapper only 70 Lines of Code. So for your use case it might be easier to write some helpers on your own.

API

The simple syntax you can see in the .d.ts file:

/// <reference types="node" />
import { UserOptions } from "docx-templates/lib/types";
declare type modifiedConfig = Omit<UserOptions, "template" | "queryVars">;
declare type DATA = Record<string, any>;
declare type Template = UserOptions["template"];
export declare class Gotenberg {
    protected url: string;
    constructor(url: string);
    fillDocToPdf(file: Template, data: DATA[], config?: modifiedConfig): Promise<NodeJS.ReadableStream>;
    fillDocToPdf(file: Template, data: [DATA], config: modifiedConfig, onlyDocx: true): Promise<ArrayBufferLike>;
}

As you can see we export a class Gotenberg wich has to be created with a url. The class has one method fillDocToPdf. This expects a Buffer as a file and a Array of Data objects as data. Additionaly we can provide a config object. This ist nearly the same config as the options of docx-templates. If we provide a query-Resolver for data (so a function) the data will be injected as queryVars not as data. If data is a single Object you can provid onlyDocx as true and get a ArrayBufferLike for the filled docx file. In all other cases you get a NodeJS.ReadableStream as a Result.
