This library adds the ability to "painlessly" change your Swagger documentation theme.

Installation

npm

npm i swagger-themes

yarn

yarn add swagger-themes

Example usage

Connecting and using the library

const { SwaggerTheme, SwaggerThemeNameEnum } = require('swagger-themes');

const theme = new SwaggerTheme();
const darkStyle = theme.getBuffer(SwaggerThemeNameEnum.DARK); // Getting a Style

Use with Express

Standard Example

Standard dark theme connection with Express. The connection takes place via the swagger-ui-express library

const express = require('express');
const swaggerUi = require('swagger-ui-express');
const { SwaggerTheme; SwaggerThemeNameEnum } = require('swagger-themes');
const swaggerDocument = require('./swagger.json');

const app = express();
const theme = new SwaggerTheme();

const options = {
  explorer: true,
  customCss: theme.getBuffer(SwaggerThemeNameEnum.DARK)
};

app.use('/api-docs', swaggerUi.serve, swaggerUi.setup(swaggerDocument, options));

Two Swagger document

Connecting 2 documentation files. For example - 2 different themes are used

const express = require('express');
const swaggerUi = require('swagger-ui-express');
const { SwaggerTheme, SwaggerThemeNameEnum } = require('swagger-themes');
const swaggerDocument = require('./swagger.json');

const app = express();
const theme = new SwaggerTheme();

const optionsV1 = {
  explorer: true,
  customCss: theme.getBuffer(SwaggerThemeNameEnum.DARK)
};
const optionsV2 = {
  explorer: true,
  customCss: theme.getBuffer(SwaggerThemeNameEnum.CLASSIC)
}

app.use('/api-docs/v1', swaggerUi.serve, swaggerUi.setup(swaggerDocument, optionsV1)); // Dark theme documentation
app.use('/api-docs/v2', swaggerUi.serve, swaggerUi.setup(swaggerDocument, optionsV2)); // Classic theme documentation

Get default config

The method of getting the default config for the swagger library is ui-express

const express = require('express');
const swaggerUi = require('swagger-ui-express');
const { SwaggerTheme, SwaggerThemeNameEnum } = require('swagger-themes');
const swaggerDocument = require('./swagger.json');

const app = express();
const theme = new SwaggerTheme();

const optionsV1 = theme.getDefaultConfig(SwaggerThemeNameEnum.DARK);
const optionsV2 = theme.getDefaultConfig(SwaggerThemeNameEnum.CLASSIC);

app.use('/api-docs/v1', swaggerUi.serve, swaggerUi.setup(swaggerDocument, optionsV1)); // Dark theme documentation
app.use('/api-docs/v2', swaggerUi.serve, swaggerUi.setup(swaggerDocument, optionsV2)); // Classic theme documentation

Use with Fastify

Standard Example

Standard dark theme connection with Fastify. The connection takes place via the @fastify/swagger and @fastify/swagger-ui library

const fastify = require('fastify')({ logger: true })
const { SwaggerTheme, SwaggerThemeNameEnum } = require('swagger-themes');

const theme = new SwaggerTheme();
const content = theme.getBuffer(SwaggerThemeNameEnum.DARK);

fastify.register(require('@fastify/swagger'));
fastify.register(require('@fastify/swagger-ui'), {
  theme: {
    css: [
      { filename: 'theme.css', content: content }
    ],
  }
})

fastify.listen({ port: 3000 }, (err) => {
  if (err) throw err
})

Use with NestJS

Standard Example

Standard dark theme connection with NestJS. The connection takes place via the @nestjs/swagger library

// file main.ts
import { NestFactory } from '@nestjs/core';
import { SwaggerModule, DocumentBuilder } from '@nestjs/swagger';
import { SwaggerTheme, SwaggerThemeNameEnum } from 'swagger-themes';
import { AppModule } from './app.module';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);

  const config = new DocumentBuilder()
    .setTitle('Cats example')
    .setDescription('The cats API description')
    .setVersion('1.0')
    .addTag('cats')
    .build();
  const document = SwaggerModule.createDocument(app, config);
  const theme = new SwaggerTheme();
  const options = {
    explorer: true,
    customCss: theme.getBuffer(SwaggerThemeNameEnum.DARK)
  };
  SwaggerModule.setup('api', app, document, options);

  await app.listen(3000);
}
bootstrap();

Two Swagger document

Connecting 2 documentation files. For example - 2 different themes are used

// file main.ts
import { NestFactory } from '@nestjs/core';
import { SwaggerModule, DocumentBuilder } from '@nestjs/swagger';
import { SwaggerTheme, SwaggerThemeNameEnum } from 'swagger-themes';
import { AppModule } from './app.module';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);

  const config = new DocumentBuilder()
    .setTitle('Cats example')
    .setDescription('The cats API description')
    .setVersion('1.0')
    .addTag('cats')
    .build();
  const document = SwaggerModule.createDocument(app, config);
  const theme = new SwaggerTheme();
  const optionsV1 = {
    explorer: true,
    customCss: theme.getBuffer(SwaggerThemeNameEnum.DARK)
  };
  const optionsV2 = {
    explorer: true,
    customCss: theme.getBuffer(SwaggerThemeNameEnum.CLASSIC)
  };
  SwaggerModule.setup('api-v1', app, document, optionsV1);
  SwaggerModule.setup('api-v2', app, document, optionsV2);

  await app.listen(3000);
}
bootstrap();

Get default config

The method of getting the default config for the swagger library is @nestjs/swagger

// file main.ts
import { NestFactory } from '@nestjs/core';
import { SwaggerModule, DocumentBuilder } from '@nestjs/swagger';
import { SwaggerTheme, SwaggerThemeNameEnum } from 'swagger-themes';
import { AppModule } from './app.module';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);

  const config = new DocumentBuilder()
    .setTitle('Cats example')
    .setDescription('The cats API description')
    .setVersion('1.0')
    .addTag('cats')
    .build();
  const document = SwaggerModule.createDocument(app, config);
  const theme = new SwaggerTheme();
  const optionsV1 = theme.getDefaultConfig(SwaggerThemeNameEnum.DARK);
  const optionsV2 = theme.getDefaultConfig(SwaggerThemeNameEnum.CLASSIC);
  
  SwaggerModule.setup('api-v1', app, document, optionsV1);
  SwaggerModule.setup('api-v2', app, document, optionsV2);

  await app.listen(3000);
}
bootstrap();
