426 Upgrade Required

You need to switch to a different, usually newer or more secure, protocol (like upgrading to TLS 1.3 or HTTP/2).

When and Why to Use It

Use this if you force clients to use WebSockets, or force them to upgrade from HTTP/1.1 to HTTP/2.

Usage Examples

import { HttpException, get } from 'shokupan';

export const getResource = get('/resource', () => {
    throw new HttpException('Upgrade Required', 426);
});

import { Controller, Get, HttpException } from 'shokupan';

@Controller('/api')
export class ExampleController {
    @Get('/resource')
    getResource() {
        throw new HttpException('Upgrade Required', 426);
    }
}

import express from 'express';
const app = express();

app.get('/resource', (req, res) => {
    res.status(426).json({ error: 'Upgrade Required' });
});

import { Controller, Get, HttpException } from '@nestjs/common';

@Controller('api')
export class ExampleController {
  @Get('resource')
  getResource() {
    throw new HttpException('Upgrade Required', 426);
  }
}

import Koa from 'koa';
const app = new Koa();

app.use(async ctx => {
  if (ctx.path === '/resource' && ctx.method === 'GET') {
    ctx.status = 426;
    ctx.body = { error: 'Upgrade Required' };
  }
});
