Quirks
OpineReciever and HTTPReceiver/SocketModeReciever req/res types are not compatible. This causes trouble when providing a custom callback for built-in oauth failure / success (if you’re not using built-in oauth / not implementing custom callbacks for failure / success, you don’t have to worry about this). This requires a type guard (See simpler alternative below).
import { ServerRequest } from "https://deno.land/std@0.87.0/http/server.ts"
import {
ParamsDictionary,
Request as OpineRequest,
Response as OpineResponse,
} from "https://deno.land/x/opine@1.1.0/mod.ts"
const customCallbackOptions = {
failure: async (
req: ServerRequest | OpineRequest<ParamsDictionary, any, any>,
res?: OpineResponse<any>,
) => {
if (isOpineRequest(req)) {
// Your custom code here, req is Request<ParamsDictionary, any, any> and res is Response<any> from deno.land/x/opine
// Example:
res?.setStatus(500).send(
"<html><body><h1>OAuth failed!</h1><div>See stderr for errors.</div></body></html>",
)
} else {
// Your custom code here, req is a std/http ServerRequest, res is undefined
// Example:
await req.respond({
status: 500,
headers: new Headers({
"Content-Type": "text/html",
}),
body:
`<html><body><h1>OAuth failed!</h1><div></div></body></html>`,
})
}
function isOpineRequest(
_req: ServerRequest | OpineRequest<ParamsDictionary, any, any>,
res?: OpineResponse<any>,
): _req is OpineRequest<ParamsDictionary, any, any> {
return !!res // If res exists, OpineReciever is being used since only 'req' exists for HTTPReciever and SocketModeReceiver
}
},
}Alternatively, just specify the correct type according to your Receiver (if you don’t specify this, its HTTPReceiver by default)
- For HTTPReceiver (default) / SocketModeReceiver
import { ServerRequest } from "https://deno.land/std@0.87.0/http/server.ts"
const customCallbackOptions = {
failure: async (req: ServerRequest) => {
// Your custom code here
// Example:
await req.respond({
status: 500,
headers: new Headers({
"Content-Type": "text/html",
}),
body: `<html><body><h1>OAuth failed!</h1><div></div></body></html>`,
})
},
}- For OpineReceiver
import {
ParamsDictionary,
Request as OpineRequest,
Response as OpineResponse,
} from "https://deno.land/x/opine@1.1.0/mod.ts"
const customCallbackOptions = {
failure: async (
req: OpineRequest<ParamsDictionary, any, any>,
res: OpineResponse<any>,
) => {
// Your custom code here, req is Request<ParamsDictionary, any, any> and res is Response<any> from deno.land/x/opine
// Example:
res?.setStatus(500).send(
"<html><body><h1>OAuth failed!</h1><div>See stderr for errors.</div></body></html>",
)
},
}
