NestJS ReDoc (Swagger UI Alternative) - Jozefazz Version

Introduction

I have tried most of the Redoc integrate NestJS solutions available on the market, but due to a lack of maintenance over a long period, many outdated packages were being used, leading to installation failures. This version has been modified and improved, allowing for perfect integration with NestJS 10.0.0

-Jozefazz

Features

- Customizable theme
- It's almost a drop in replacement for you current swagger UI, you only need to import this package and modify any settings you may want to change (e.g: Page title, ReDoc options)

NB: Please read the ReDoc Documentation firstly.

🗿 Installation

Using npm: npm install @jozefazz/nestjs-redoc

How to use

You need to install the Swagger Module first if you want to get definitions updated with your project.

In future versions you will be able to pass a URL parameter as document, but for the moment you need this document object from the swagger module

``typescript
const options = new DocumentBuilder()
.setTitle('Look, i have a title')
.setDescription('A very nice description')
.setBasePath('/api/v1')
.build();
const document = SwaggerModule.createDocument(app, options);
`

Then add the following example code.

Note: All properties are optional, if you don't specify a title we will fallback to the one you used in your DocumentBuilder instance.

`typescript
const redocOptions: RedocOptions = {
title: 'Hello Nest',
logo: {
url: 'https://redocly.github.io/redoc/petstore-logo.png',
backgroundColor: '#F0F0F0',
altText: 'PetStore logo'
},
sortPropsAlphabetically: true,
hideDownloadButton: false,
hideHostname: false,
auth: {
enabled: true,
user: 'admin',
password: '123'
},
tagGroups: [
{
name: 'Core resources',
tags: ['cats'],
},
],
};
// Instead of using SwaggerModule.setup() you call this module
await RedocModule.setup('/docs', app, document, redocOptions);
`

Create a file "setup.redoc.ts"
`typescript
import type { INestApplication } from '@nestjs/common';
import { DocumentBuilder, SwaggerModule } from '@nestjs/swagger';
import { RedocModule, RedocOptions } from '@jozefazz/nestjs-redoc';
import * as process from 'process';

export async function setupRedoc(app: INestApplication) {
const documentBuilder = new DocumentBuilder()
.setTitle(${process.env.DOCS_TITLE})
.setVersion('1.0')
.setDescription('Powered by Jozefazz')
.addBearerAuth(
{
description: Please enter token in following format: Bearer ,
name: 'Authorization',
bearerFormat: 'Bearer',
scheme: 'Bearer',
type: 'http',
in: 'Header',
},
'access-token',
);

if (process.env.API_VERSION) {
documentBuilder.setVersion(process.env.API_VERSION);
}

const document = SwaggerModule.createDocument(app, documentBuilder.build());
const redocOptions: RedocOptions = {
title: ${process.env.DOCS_TITLE},
logo: {
url: ${process.env.DOCS_LOGO},
backgroundColor: '#d0e8c5',
altText: 'LOGO',
},
theme: {
typography: {
fontSize: '16px',
fontWeightBold: '900',
},
sidebar: {
backgroundColor: '#d0e8c5',
},
rightPanel: {
backgroundColor: '#01312b',
},
},
sortPropsAlphabetically: true,
hideDownloadButton: false,
hideHostname: false,
noAutoAuth: true,
pathInMiddlePanel: true,
auth: {
enabled: true,
user: 'admin',
password: ${process.env.DOCS_PASSWORD},
},
tagGroups: [
{
name: 'Core resources',
tags: ['authentication', 'user'],
},
],
};
await RedocModule.setup('docs', app, document, redocOptions);
console.info(
Redoc Documentation: http://localhost:${process.env.PORT}/docs,
);
}

`
In your main.ts, add this line before "await app.listen(3000);"
`
await setupRedoc(app);
