# Debugging
|
|
|
|
When debugging your code, you can use more than just `console.log` or attaching the node process to a debugger. Another option is to use `ctx.state.json` to provide a custom object for debugging.
|
|
|
|
## Using `ctx.state.json`
|
|
|
|
To pass a custom object to ctx.state.json for debugging, follow these steps:
|
|
|
|
1. Create your custom object.
|
|
2. Assign your object to `ctx.state.json`.
|
|
3. Access the corresponding route + `.debug.json` to view your object. For example, if you want to debug the route `/furstar/characters/:lang?`, you can access the URL: `/furstar/characters/en.debug.json`
|
|
|
|
Here's an example of how to use `ctx.state.json` taken from [furstar/index.js](https://github.com/DIYgod/RSSHub/blob/master/lib/v2/furstar/index.js)
|
|
|
|
```js
|
|
const info = utils.fetchAllCharacters(res.data, base);
|
|
|
|
ctx.state.json = {
|
|
info,
|
|
};
|
|
```
|
|
|
|
In the example above, we're passing the `info` object to `ctx.state.json`, which we can then access using the corresponding route + `.debug.json`.
