Quick start

You can use @coherent.js/core rendering inside Express handlers.

JavaScript (ESM):

import express from 'express';
import { renderToString } from '@coherent.js/core';

const app = express();

app.get('/', async (_req, res) => {
  const html = await renderToString({ div: { text: 'Hello from Express + Coherent' } });
  res.type('html').send(html);
});

app.listen(3000, () => console.log('http://localhost:3000'));

TypeScript:

import express, { Request, Response } from 'express';
import { renderToString } from '@coherent.js/core';

const app = express();

app.get('/', async (_req: Request, res: Response) => {
  const html = await renderToString({ div: { text: 'Hello TS' } });
  res.type('html').send(html);
});

app.listen(3000);
