koa-onerror v4.2.0
koa-onerror
an error handler for koa, hack ctx.onerror.
different with koa-error:
- we can not just use try catch to handle all errors, steams' and events'
errors are directly handle by
ctx.onerror
, so if we want to handle all errors in one place, the only way i can see is to hackctx.onerror
. - it is more customizable.
install
npm install koa-onerror
Usage
const fs = require('fs');
const koa = require('koa');
const onerror = require('koa-onerror');
const app = new koa();
onerror(app);
app.use(ctx => {
// foo();
ctx.body = fs.createReadStream('not exist');
});
Options
onerror(app, options);
- all: if options.all exist, ignore negotiation
- text: text error handler
- json: json error handler
- html: html error handler
- redirect: if accepct html, can redirect to another error page
check out default handler to write your own handler.
Status and Headers
koa-onerror
will automatic set err.status
as response status code, and err.headers
as response headers.
