title: "ADR: Logging errors"
---

## Background

After debugging multiple errors over the last few years, we've consistently found that when something goes wrong, we
would like as much context as possible to debug faster.

## Decision

When we log at the error level, we should give the person debugging as much information as possible.
As such, please include the error as a second argument to `logger.error`. This will include the stacktrace in the log
message and make it a lot easier to figure out where the error is coming from

### Change

#### Previously

```typescript
function errors() {
    try {
    } catch (e) {
        this.logger.error(`Something went wrong {$e}`);
    }
}
```

to

#### Now (Recommended)

```typescript
function errors() {
    try {
    } catch (e) {
        this.logger.error('Something went wrong', e);
    }
}
```
