--- title: Bundlers pagination_prev: demos/index pagination_next: demos/grid/index sidebar_position: 19 sidebar_custom_props: skip: 1 --- import current from '/version.js'; import Tabs from '@theme/Tabs'; import TabItem from '@theme/TabItem'; import CodeBlock from '@theme/CodeBlock'; import {useCurrentSidebarCategory} from '@docusaurus/theme-common'; SheetJS predates ECMAScript modules and most bundler tools. As best practices have evolved, stress testing SheetJS libraries have revealed bugs in bundlers and other tools. This demo collects various notes and provides basic examples. :::note pass Issues should be reported to the respective bundler projects. Typically it is considered a bundler bug if the tool cannot properly handle JS libraries. ::: The following tools are covered in separate pages: ## Dojo Integration details are included [in the "AMD" installation](/docs/getting-started/installation/amd#dojo-toolkit) Complete Examples are included [in the "Dojo" demo](/docs/demos/frontend/legacy#dojo-toolkit) ## Snowpack Snowpack works with no caveats.
Complete Example (click to show) :::note This demo was last tested on 2023 October 21 against Snowpack `3.8.8` ::: 0) Initialize a new project: ```bash mkdir sheetjs-snowpack cd sheetjs-snowpack npm init -y ``` 1) Install the tarball using a package manager: {`\ npm i --save https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`} {`\ pnpm install https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`} {`\ yarn add https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`} 2) Save the following to `index.js`: ```js title="index.js" // highlight-next-line import { utils, version, writeFileXLSX } from 'xlsx'; document.getElementById("xport").addEventListener("click", async() => { /* fetch JSON data and parse */ const url = "https://sheetjs.com/data/executive.json"; const raw_data = await (await fetch(url)).json(); /* filter for the Presidents */ const prez = raw_data.filter(row => row.terms.some(term => term.type === "prez")); /* flatten objects */ const rows = prez.map(row => ({ name: row.name.first + " " + row.name.last, birthday: row.bio.birthday })); /* generate worksheet and workbook */ const worksheet = utils.json_to_sheet(rows); const workbook = utils.book_new(); utils.book_append_sheet(workbook, worksheet, "Dates"); /* fix headers */ utils.sheet_add_aoa(worksheet, [["Name", "Birthday"]], { origin: "A1" }); /* calculate column width */ const max_width = rows.reduce((w, r) => Math.max(w, r.name.length), 10); worksheet["!cols"] = [ { wch: max_width } ]; /* create an XLSX file and try to save to Presidents.xlsx */ writeFileXLSX(workbook, "Presidents.xlsx"); }); ``` 3) Create a small HTML page that loads the script. Save to `index.html`: ```html title="index.html"

``` :::note pass Unlike other bundlers, Snowpack requires a full page including `HEAD` element. ::: 4) Build for production: ```bash npx snowpack@3.8.8 build ``` 5) Start a local HTTP server, then go to `http://localhost:8080/` ```bash npx http-server build/ ``` Click on "Click here to export" to generate a file.
## WMR WMR works with no caveats.
Complete Example (click to show) :::note This demo was last tested on 2023 Oct 21 against WMR `3.8.0` ::: 0) Initialize a new project: ```bash mkdir sheetjs-wmr cd sheetjs-wmr npm init -y ``` 1) Install the tarball using a package manager: {`\ npm i --save https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`} {`\ pnpm install https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`} {`\ yarn add https://cdn.sheetjs.com/xlsx-${current}/xlsx-${current}.tgz`} 2) Save the following to `index.js`: ```js title="index.js" // highlight-next-line import { utils, version, writeFileXLSX } from 'xlsx'; document.getElementById("xport").addEventListener("click", async() => { /* fetch JSON data and parse */ const url = "https://sheetjs.com/data/executive.json"; const raw_data = await (await fetch(url)).json(); /* filter for the Presidents */ const prez = raw_data.filter(row => row.terms.some(term => term.type === "prez")); /* flatten objects */ const rows = prez.map(row => ({ name: row.name.first + " " + row.name.last, birthday: row.bio.birthday })); /* generate worksheet and workbook */ const worksheet = utils.json_to_sheet(rows); const workbook = utils.book_new(); utils.book_append_sheet(workbook, worksheet, "Dates"); /* fix headers */ utils.sheet_add_aoa(worksheet, [["Name", "Birthday"]], { origin: "A1" }); /* calculate column width */ const max_width = rows.reduce((w, r) => Math.max(w, r.name.length), 10); worksheet["!cols"] = [ { wch: max_width } ]; /* create an XLSX file and try to save to Presidents.xlsx */ writeFileXLSX(workbook, "Presidents.xlsx"); }); ``` 3) Create a small HTML page that loads the script.
