Oak middleware for error handling and logging
## Usage
* As an application middleware
```ts
import { errorHandlerMiddleware } from "https://raw.githubusercontent.com/halvardssm/oak-middleware-error-logger/master/mod.ts"
import { Middleware } from "https://deno.land/x/oak/mod.ts";
const app = new Application();
app.use(
errorHandlerMiddleware({
fallback: async (err, ctx) => {
await logger({ logInfo: err.toString() })
if (isHttpError(err)) {
ctx.throw(err.status, err.message)
} else {
ctx.throw(ErrorStatus.InternalServerError, "Server error")
}
},
})
);
await app.listen(appOptions);
```
* As a router middleware
```ts
import { errorHandlerMiddleware, logger } from "https://raw.githubusercontent.com/halvardssm/oak-middleware-error-logger/master/mod.ts"
import { RouterMiddleware } from "https://deno.land/x/oak/mod.ts";
const app = new Application();
app.use(errorHandlerMiddleware({
fallback: (err, ctx) => {
throw new Error(err as string);
},
cases: {
404: (err, ctx) => someMehod(),
[ErrorStatus.BadRequest]: (err, ctx) => logger({ logInfo: err })
}
}));
await app.listen(appOptions);
```
