@IgorKhromov Remember, the cache middleware (including toggle middleware shown here) gets called at the last moment, before res.end
, rather than at the entry to the route like typical middleware (it does this by hijacking the res.end
to delay its execution). By this point, you would have set 403, 404, 500 statuses depending on the response.
This particular middleware toggle simply returns true if the statusCode === 200, so if that returns true, the middleware continues on to cache the response.
That help at all? Test it out by setting the statusCode to say, 400 within your route and see if it caches. It shouldn't! If it does, please reopen this as a bug and I'll resolve and add test coverage.
Cheers!

I think I'm also missing something here...
const router = require('express').Router()
const apicache = require('apicache')
const cache = apicache.middleware
const statusOkOrNotFound = (req, res) => {
console.log("check status " + res.statusCode)
return res.statusCode === 200 || res.statusCode === 404
}
const cacheValid = cache('5 minutes', statusOkOrNotFound)
router.get('/api/test', cacheValid, (req, res) => {
console.log("API request, send fake error")
res.status(500).send("fake error")
return
}
When I execute this request, I see this trace in unexpected order:
check status 200
API request, send fake error
And this response:
HTTP/1.1 500 Internal Server Error
x-powered-by: Express
cache-control: max-age=300
The only difference I see between this and your example is I do:
const router = require('express').Router()
router.get(...)
And your example shows:
const app = require('express')
app.get(...)

I'm having the same issue, check is triggered long before the call is done - therefore it caches every response
