ejs-stream2
A nodejs stream template renderer based on ejs syntax.
The library ejs supports string only to output,
but we need to output stream sometimes(see #102).
For example, with React'srenderToNodeStream API. This library makes it possible.
Install
Please note the package name is ejs-stream2 rather than ejs-stream in
npm, for ejs-stream is occupied by another people.
npm install ejs-stream2
# or var yarn
yarn add ejs-stream2Usage
import { compile } from 'ejs-stream2';
import express from 'express';
import { renderToNodeStream } from 'react-dom/server';
const template = compile(`
<!DOCTYPE html>
<html>
<head>
<title><%= title %></title>
</head>
<body>
<div id=root><%- content %></div>
<script async defer src="<%- scriptBundle %>"></script>
</body>
</html>
`);
const app = express();
app.get('/', (req, res) => {
const stream = template({
title: 'Hello world',
content: renderToNodeStream(<App />),
scriptBundle: '/bundle.js',
});
// please note you must listen the `error` event of `Readable`, or your
// application with exit if error occurs.
stream.on('error', (error) => {
console.error(error);
res.end();
});
stream.pipe(res);
});Features
- Support all the syntax set of
ejs, see syntax.md - Support the following variables to output directly by
<%- variable %>or<%= variable %>NodeJS.ReadableStream | Uint8Array | stringPromise<NodeJS.ReadableStream | Uint8Array | string>Array<NodeJS.ReadableStream | Uint8Array | string | Promise<NodeJS.ReadableStream | Uint8Array | string>>
For simplify the test cases, we removed the following features from ejs
- file system relative features, such as
renderFile,include - options to change delimiters
asyncmode- cache
