# dejs
[](https://github.com/syumai/dejs/actions)
- [ejs](https://ejs.co) template engine for
[deno](https://github.com/denoland/deno).
## Features
### Supported
- <%= %> Output escaped value
- <%- %> Output raw value
- <%# %> Comment (nothing will be shown)
- <% %> Evaluate (use control flow like: if, for)
- include partial ejs template
### Not supported
- All other features of ejs
## Usage
```ts
import * as dejs from "https://deno.land/x/[email protected]/mod.ts";
```
- **`renderFile`** `(filePath: string, params: Params): Promise`
- renders from file, outputs Deno.Reader
- **`render`** `(body: string, params: Params): Promise`
- renders from string, outputs Deno.Reader
- **`renderFileToString`** `(filePath: string, params: Params): Promise`
- renders from file, outputs string
- **`renderToString`** `(body: string, params: Params): Promise`
- renders from string, outputs string
- **`compile`** `(reader: Reader): Promise`
- only compiles ejs and returns `Template(params: Params): string`
- use this to cache compiled result of ejs
### Render from file
- template.ejs
```ejs
<% if (name) { %>
hello, <%= name %>!
<% } %>
```
- index.ts
```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
```sh
$ deno index.ts
hello, world!
```
### Render from string
```ts
const { cwd, stdout, copy } = Deno;
import { render } from "https://deno.land/x/dejs/mod.ts";
const template = `
<% if (name) { %>
hello, <%= name %>!
<% } %>
`;
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
```ejs
await include(filePath, params)
```
#### Example
- views/header.ejs
```ejs
<%- title %>
```
- views/footer.ejs
```ejs
```
- views/main.ejs
```
<%- await include('views/header.ejs', { title: 'include example' }) %>
hello, world!
<%- await include('views/footer.ejs') %>
```
- index.ts
```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
```sh
$ deno index.ts
include example
hello, world!
```
