koa-charset

Use iconv-lite to encode the body and set charset to content-type.

Install

# npm ..
npm i koa-charset
# yarn ..
yarn add koa-charset

Usage

const Koa = require('koa');
const charset = require('koa-charset');

const app = new Koa();

app.use(charset());
app.use(function (ctx) {
  ctx.body = '你好';
  ctx.type = 'text/html; charset=gbk';
});

app.listen(3000);

Options

• charset: set global charset by options.charset

Manually turning charset on and off

You can set ctx.charset to cover the global charset.

app.use(function (ctx) {
  ctx.charset = 'gb2312';
  ctx.body = '你好';
});

You can disable charset by ctx.charset = false.

app.use(function (ctx) {
  ctx.charset = false;
  ctx.body = 'hello';
});

also this module will get the charset from Content-Type, so you can just use koa-charset, then this middleware will automatically re-encode the body only if the charset is not utf8.

const app = new Koa();
app.use(charset());
app.use(function () {
  const charset = ctx.acceptsCharsets('utf8', 'gbk') || 'utf8';
  ctx.vary('accept-charset');
  ctx.type = `text/plain; charset=${charset}`;
  ctx.body = 'something';
});
