Word Add-in with TypeScript
Before you read this page you should read with JavaScript
Generate package.json file
Open File Explorer and browse to the (C:\temp\notepad) folder.
Create a new subfolder called "word-typescript" (C:\temp\notepad\word-typescript).
Open a command prompt (as administrator).
Change to that folder and initialise npm.
cd c:\temp\notepad\word-typescript
npm init
Press Enter to accept all the defaults.
This will create a "package.json" file in the folder.
(C:\temp\notepad\word-typescript).
Install Webpack
npm install --save-dev webpack
npm install --save-dev webpack-cli
npm install --save-dev webpack-dev-server

npm install --save-dev @babel/core
npm install --save-dev @babel/preset-typescript
Install TypeScript
more information
This lets you use the TypeScript compiler.

Install Type Definitions
This lets Typescript perform the necessary type checking at compile type.
npm install --save-dev @types/office-js
Edit package.json file
Open NotePad++ and drag the "package.json" file onto it.
Change the main parameter from 'index.js' to 'index.ts'.

}
}
Create index.html
Open File Explorer in the root folder (C:\temp\notepad\word-typescript).
Create a new subfolder called 'code' (C:\temp\notepad\word-typescript\code).
Create a NotePad file with the following contents and save it as 'index.html'.
This file contains html code and includes a link to Office.js.
<!DOCTYPE html>
<html>
<head>
<script src="https://appsforoffice.microsoft.com/lib/1/hosted/Office.js"
type="text/javascript"> </script>
</head>
<body>
<h1>Word Demo</h1>
<div id="app"></div>
</body>
</html>
Create index.ts
Open File Explorer in the folder (C:\temp\notepad\word-typescript\code).
Create a NotePad file with the following contents and save it as 'index.ts'.
window.onload = function Start() {
console.log('hello world');
var app_1 = document.getElementById("app");
app_1.innerHTML = app_1.innerHTML + '<br>' +
'<input ' +
'type="button" ' +
'value="Add Data" ' +
'onclick="loadWordData();" />';
app_1.innerHTML = app_1.innerHTML + '<br><br><br>' +
'<textarea ' +
'id="textareaID" ' +
'rows="10" ' +
'cols="35">' +
'console.log' +
'</textarea>';
};
Office.initialize = function (reason) {
}
window.loadWordData = loadWordData;
function loadWordData() {
fun_WindowLog('--------------------');
Word.run(function (ctx) {
let myTable = new Office.TableData();
myTable.headers = ["First Name", "Last Name", "Grade"];
myTable.rows = [["Brittney", "Booker", "A"], ["Sanjit", "Pandit", "C"], ["Naomi", "Peacock", "B"]];
Office.context.document.setSelectedDataAsync(myTable, { coercionType: Office.CoercionType.Table });
fun_WindowLog('Another Table Added');
return ctx.sync();
});
}
function fun_WindowLog(
newText: any) {
window.console.log(newText);
let element2 = document.getElementById("textareaID");
element2.textContent = newText + "\n" + element2.textContent;
}
Create webpack.config.js file
Open File Explorer in the root folder (C:\temp\notepad\word-typescript).
Create a NotePad file with the following contents and save it as 'webpack.config.js'.
This file tells webpack the location and filename of our top level/entry typescript file ("index.ts").
This file tells webpack to bundle all the javascript files into a single file called "webpackbundle.js".
var HTMLWebpackPlugin = require('html-webpack-plugin');
var HTMLWebpackPluginConfig = new HTMLWebpackPlugin({
template: __dirname + '/code/index.html',
filename: 'index.html',
inject: 'body'
});
module.exports = {
entry: __dirname + '/code/index.ts',
output: {
filename: 'webpackbundle.js',
path: __dirname + '/build'
},
module: {
rules: [
{
test: /.ts$/,
exclude: /node_modules/,
use : {
loader: 'babel-loader',
options: {
presets: [ '@babel/preset-typescript' ]
}
}
}
]
},
plugins: [HTMLWebpackPluginConfig]
};
The "webpackbundle.js" file will be automatically generated and used on the local server.
This file is not saved or accessible anywhere in the root folder (C:\temp\officejs\word-typescript).
Launch Browser
You are now in a position to launch webpack and start the local development server.
Open a command prompt (as administrator).
Change to the corresponding folder.
cd c:\temp\notepad\word-typescript
Execute the following 2 commands.
node ./node_modules/webpack/bin/webpack --mode development
node ./node_modules/webpack-dev-server/bin/webpack-dev-server --mode development
Open a Microsoft Edge browser and type in the URL - localhost:8080
Create manifest.xml
Create a NotePad file with the following contents and save it as 'manifest.xml'.
<?xml version="1.0" encoding="UTF-8"?>
