Usage

import * as dejs from "https://deno.land/x/dejs@0.10.3/mod.ts";

renderFile (filePath: string, params: Params): Promise<Deno.Reader>
- renders from file, outputs Deno.Reader
render (body: string, params: Params): Promise<Deno.Reader>
- renders from string, outputs Deno.Reader
renderFileToString (filePath: string, params: Params): Promise<string>
- renders from file, outputs string
renderToString (body: string, params: Params): Promise<string>
- renders from string, outputs string
compile (reader: Reader): Promise<Template>
- only compiles ejs and returns Template(params: Params): string
- use this to cache compiled result of ejs

Render from file

template.ejs

<body>
  <% if (name) { %>
    <h1>hello, <%= name %>!</h1>
  <% } %>
</body>

index.ts

const { cwd, stdout, copy } = Deno;
import { renderFile } from "https://deno.land/x/dejs/mod.ts";

const output = await renderFile(`${cwd()}/template.ejs`, {
  name: "world",
});
await copy(output, stdout);

console

$ deno index.ts
<body>

    <h1>hello, world!</h1>

</body>

Render from string

const { cwd, stdout, copy } = Deno;
import { render } from "https://deno.land/x/dejs/mod.ts";

const template = `<body>
  <% if (name) { %>
    <h1>hello, <%= name %>!</h1>
  <% } %>
</body>`;

const output = await render(template, {
  name: "world",
});
await copy(output, stdout);

Include partial ejs template

To include template from other file, use include function in ejs.
include resolves views from relative path from executed ts / js file. (not from ejs template file).
- This behavior may change in the future.

Usage

await include(filePath, params)

Example

views/header.ejs

<html>
<head>
  <title><%- title %></title>
</head>
<body>

views/footer.ejs

</body>
</html>

views/main.ejs

<%- await include('views/header.ejs', { title: 'include example' }) %>
<h1>hello, world!</h1>
<%- await include('views/footer.ejs') %>

index.ts

const { cwd, stdout, copy } = Deno;
import { renderFile } from "https://deno.land/x/dejs/mod.ts";

const output = await renderFile(`${cwd()}/views/main.ejs`);
await copy(output, stdout);

console

$ deno index.ts
<html>
<head>
  <title>include example</title>
</head>
<body>
<h1>hello, world!</h1>
</body>
</html>
