I used Yeoman for generating my Office add-in. And got stuck with an IE11-compatible issue. here is it: enter image description here
I check the taskpane.js file find it still using deconstruct expression which is from ES6. enter image description here
after that, I checked the webpack.config.js file. I google it, so the babel-loader should be used to convert ES6 to ES5. here is the file:
/* eslint-disable no-undef */
const devCerts = require("office-addin-dev-certs");
const CopyWebpackPlugin = require("copy-webpack-plugin");
const HtmlWebpackPlugin = require("html-webpack-plugin");
const webpack = require("webpack");
const urlDev = "https://localhost:3000/";
const urlProd = "xxxxxxx"; // CHANGE THIS TO YOUR PRODUCTION DEPLOYMENT LOCATION
async function getHttpsOptions() {
const httpsOptions = await devCerts.getHttpsServerOptions();
return { cacert: httpsOptions.ca, key: httpsOptions.key, cert: httpsOptions.cert };
}
module.exports = async (env, options) => {
const dev = options.mode === "development";

https: env.WEBPACK_BUILD || options.https !== undefined ? options.https : await getHttpsOptions(),

},
};
return config;
};
I found it works in my code but not the library. before: enter image description here
after: enter image description here
I have tried to add one more rule in config file, like:
{
test: /\.(ts|tsx)$/,
use: [
"react-hot-loader/webpack",
{
loader: "babel-loader",
options: {
presets: ["@babel/preset-typescript"],
}
},
],
exclude: /node_modules/,
},
