Note on Compatiblity
This is module is mostly compatible with its node
counterpart. However,
InstallProvider does not contain a handleCallback function taking request
and response handlers. Instead, it has a handle function which takes a code
and a state and does not handle responding and returns a promise which
resolves / rejects to the default HTML for successes / errors, which you can
then respond with or override. This is to maximize compatiblity with various
Deno HTTP servers.
Usage
Handling requests
The following is an example of handling a request using Oak as the HTTP server
import "https://deno.land/x/dotenv@v2.0.0/load.ts"
import { nanoid } from "https://deno.land/x/nanoid@v3.0.1/mod.ts"
import { Application, Router } from "https://deno.land/x/oak/mod.ts"
import { InstallProvider } from "https://deno.land/x/slack_oauth@3.0.2/mod.ts"
// initialize the installProvider
const installer = new InstallProvider({
clientId: Deno.env.get("SLACK_CLIENT_ID")!,
clientSecret: Deno.env.get("SLACK_CLIENT_SECRET")!,
stateSecret: nanoid(),
})
const router = new Router()
router.get("/", async (ctx) => {
ctx.response.redirect(
await installer.generateInstallUrl({
scopes: ["chat:write"],
}),
)
})
router.get("/slack/oauth_redirect", async (ctx) => {
const code = ctx.request.url.searchParams.get("code")
const state = ctx.request.url.searchParams.get("state")
if (!code || !state) {
ctx.response.status = 401
ctx.response.body = "Unauthorized - Missing code or state"
return
}
try {
const successMessage = await installer.handle(code, state)
ctx.response.status = 200
ctx.response.body = successMessage
} catch (e) {
ctx.response.status = 500
ctx.response.body = e.message
}
})
const app = new Application()
app.use(router.routes())
app.use(router.allowedMethods())
await app.listen({ port: 8000 })Authorization
You can use the the installer.authorize() function to fetch data that has been saved in your installation store.
import { InstallProvider } from "https://deno.land/x/slack_oauth@3.0.2/mod.ts"
const installer = new InstallProvider({
clientId: Deno.env.get("SLACK_CLIENT_ID")!,
clientSecret: Deno.env.get("SLACK_CLIENT_SECRET")!,
stateSecret: nanoid(),
})
const result = await installer.authorize({ teamId: "my-team-ID" })
console.log(result)API
- Methods are almost identical to the node @slack/oauth (see Note on Compatiblity)
- Generated docs are available at https://doc.deno.land/https/deno.land/x/slack_oauth@3.0.2/mod.ts
