Pass Go data to TypeScript

This demonstrates how to bundle TypeScript code, and use it in a templ project.

The TypeScript code is bundled using esbuild, with templ used to serve HTML.

The code demonstrates application of onclick event handlers, and how to pass data from Go to TypeScript.

This demo passes data from server-side Go code to TypeScript code by placing the data in <script type="application/json"> tags, or data attributes (called alert-data in this example).

Note how the Go web server serves the ./assets directory, which contains the bundled TypeScript code.

Tasks

generate

templ generate

ts-install

Since it's a TypeScript project, you need to install the dependencies.

Dir: ts

npm install

ts-build-cli

If you have esbuild installed globally, you can bundle and minify the TypeScript code without using NPM. Remember to run npm install to install the dependencies first.

esbuild --bundle --minify --outfile=assets/js/index.js ts/src/index.ts

ts-build-npm

If you don't have esbuild installed globally, you can use the NPM script to build the TypeScript code.

Dir: ./ts

npm run build

run

go run .
