With this template engine, TSX files can be rendered server-side by your Express application. Unlike other JSX express renderers, this one does not rely on JSX files being transpiled by babel at runtime. Instead, TSX files are processed once by the tsc compiler.

For this to work, the templates are imported dynamically during rendering. And for this you have to provide a default export in your main TSX files. (Embeddable TSX components don't have to use a default export).

• Fast, since the JSX/TSX files do not have to be transpiled on-the-fly with every request
• Works with compiled files (.js / node) and uncompiled files (.tsx / ts-node, ts-jest, ...)

• Usage
  • Express
  • NestJS

$ npm install --save express-tsx-views

You have to set the jsx setting in your TypeScript configuration tsconfig.json to the value react and to enable esModuleInterop:

{
  "compilerOptions": {
    "jsx": "react",
    "esModuleInterop":  true,
  }
}

This template engine can be used in express and NestJS applications. The function setupReactViews() is provided, with which the engine is made available to the application.

import { setupReactViews } from 'express-tsx-views'

const options = {
  viewsDirectory: path.resolve(__dirname, '../views'),
}

setupReactViews(app, options)

The following options may be passed:

Example express app (See also example/app.ts in this project):

import express from 'express'
import { resolve } from 'path'
import { setupReactViews } from 'express-tsx-views'
import { Props } from './views/my-view'

export const app = express()

setupReactViews(app, {
  viewsDirectory: resolve(__dirname, 'views'),
  prettify: true,  // Prettify HTML output
})

app.get('/my-route', (req, res, next) => {
  const data: Props = { title: 'Test', lang: 'de' }
  res.render('my-view', data)
})

app.listen(8080)

views/my-view.tsx:

import React, { Component } from 'react'
import MyComponent from './my-component'
import { MyLayout } from './my-layout'

export interface Props {
  title: string
  lang: string
}

// Important -- use the `default` export
export default class MyView extends Component<Props> {
  render() {
    return (
      <div>Hello from React! Title: {this.props.title}</div>
    )
  }
}

express-tsx-views can also be used in NestJS. For this purpose the template engine must be made available in your main.ts:

import { setupReactViews } from 'express-tsx-views'

async function bootstrap() {
  // ...
  setupReactViews(app.getHttpAdapter().getInstance(), {
    viewsDirectory: resolve(__dirname, '../views'),
  })
}
// ...

Example controller:

import { Props } from './views/my-view'

@Get('/my-route')
@Render('my-view')
getMyRoute(): Props {
  return { title: "Hello from NestJS", lang: "de" }
}
