B33pB00p•4/12/24, 1:35 PM

herro all. I have a requirement to geosteer requests to a SIP URI depdending on our cx continent location.

I'm not much of a dev... more like a 50 year old infrastructure script kiddie.

Do you think it's just a matter of altering: https://developers.cloudflare.com/workers/examples/country-code-redirect/

to SIP URIs? Something like,
/
GEO SIP redirector
*
- Redirect users based on their location to different SIP URIs
/

export default {
async fetch(request) {
/**

A map of the SIP URIs to redirect to based on country
@param {Object} countryMap*/const countryMap = {US: "houston2.voip.ms",EU: "london1.voip.ms",CA: "houston2.voip.ms"};// Use the cf object to obtain the country of the requestconst country = request.cf.country;if (country != null && country in countryMap) {const sipUri = countryMap[country];// Remove this logging statement from your final output.console.log(`Based on ${country}-based request, your user would go to ${sipUri}.`);return new Response(null, { status: 302, headers: { "Location": `sip:${sipUri}` }});} else {// Default redirection if country is not foundreturn new Response(null, { status: 302, headers: { "Location": "sip:aaa.voip.ms" }});}},};

?

Any good resources for learning about system design using the capability security model used by worker RPCs? The Cap'n proto FAQ links out to http://zesty.ca/capmyths/usenix.pdf which I'm working through, but also would like to see some real world examples.

For instance, the RPC announcement gives the example of an auth service that returns a User stub on auth, allowing the caller to interact with the user only if auth succeeds. Let's say we wanted to add a todo list to the app. So, we spin up a few workers:

- web-srv # binds AuthService
  - fetch routes:
    - GET /todos/<todo-list-id> # get the list
    - PUT /todos/<todo-list-id> # set the list
- todo-srv
  - TodoService: Entrypoint # only accessible by auth-srv
    - todoForUser(user_id): TodoUser
  - TodoUser(user_id): RpcTarget 
    - get(id): string[]
    - set(id, string[])
- auth-srv # binds TodoService
  - AuthService: Entrypoint 
    - checkCookie() : User
  - User(user_id): RpcTarget
    - todos(): TodoUser

- web-srv # binds AuthService
  - fetch routes:
    - GET /todos/<todo-list-id> # get the list
    - PUT /todos/<todo-list-id> # set the list
- todo-srv
  - TodoService: Entrypoint # only accessible by auth-srv
    - todoForUser(user_id): TodoUser
  - TodoUser(user_id): RpcTarget 
    - get(id): string[]
    - set(id, string[])
- auth-srv # binds TodoService
  - AuthService: Entrypoint 
    - checkCookie() : User
  - User(user_id): RpcTarget
    - todos(): TodoUser

- web-srv # binds AuthService
  - fetch routes:
    - GET /todos/<todo-list-id> # get the list
    - PUT /todos/<todo-list-id> # set the list
- todo-srv
  - TodoService: Entrypoint # only accessible by auth-srv
    - todoForUser(user_id): TodoUser
  - TodoUser(user_id): RpcTarget 
    - get(id): string[]
    - set(id, string[])
- auth-srv # binds TodoService
  - AuthService: Entrypoint 
    - checkCookie() : User
  - User(user_id): RpcTarget
    - todos(): TodoUser

- web-srv # binds AuthService
  - fetch routes:
    - GET /todos/<todo-list-id> # get the list
    - PUT /todos/<todo-list-id> # set the list
- todo-srv
  - TodoService: Entrypoint # only accessible by auth-srv
    - todoForUser(user_id): TodoUser
  - TodoUser(user_id): RpcTarget 
    - get(id): string[]
    - set(id, string[])
- auth-srv # binds TodoService
  - AuthService: Entrypoint 
    - checkCookie() : User
  - User(user_id): RpcTarget
    - todos(): TodoUser

So a call sequence might be:

- browser: GET /todos/x Cookie=foo
- web-srv: AuthService.checkCookie(foo) -> User
- web-srv: User.todos() -> TodoUser
- web-srv: TodoUser.get(x) # does this go directly to todo-srv or is there a hop through auth-srv?

- browser: GET /todos/x Cookie=foo
- web-srv: AuthService.checkCookie(foo) -> User
- web-srv: User.todos() -> TodoUser
- web-srv: TodoUser.get(x) # does this go directly to todo-srv or is there a hop through auth-srv?

- browser: GET /todos/x Cookie=foo
- web-srv: AuthService.checkCookie(foo) -> User
- web-srv: User.todos() -> TodoUser
- web-srv: TodoUser.get(x) # does this go directly to todo-srv or is there a hop through auth-srv?

- browser: GET /todos/x Cookie=foo
- web-srv: AuthService.checkCookie(foo) -> User
- web-srv: User.todos() -> TodoUser
- web-srv: TodoUser.get(x) # does this go directly to todo-srv or is there a hop through auth-srv?

Maybe I'm overcomplicating this (a simple todo app certainly doesn't need all this), but I'm curious to see what it looks like to go all-in on the capability model.

Question since the docs don’t seem to have this clear, is the ja4 fingerprint included in the ja3_hash bot management variable or is this stored in a different variable?

Concurrent Subrequest Limit

As of this release, we impose a limit on the number of outgoing HTTP requests that a worker can make simultaneously. For each incoming request, a worker can make up to 6 concurrent outgoing fetch() requests.

This means that something like this:

await Promise.all(jobs.map(async (job_url) => await $fetch(job_url))

await Promise.all(jobs.map(async (job_url) => await $fetch(job_url))

await Promise.all(jobs.map(async (job_url) => await $fetch(job_url))

await Promise.all(jobs.map(async (job_url) => await $fetch(job_url))

Would take very long right?
It would do 6 + 6 + 6 + 6 until it reaches the limit of 50 per request

i dont know if im going insane at this point, but i have this weird scenario. i have a public api and a discord bot that both have the same functionality essentially, so i was thinking that i would take out the core api functionality, put it into a separate worker and make the api and discord bot have bindings to the core functions

Has someone created tests for scheduled workers with correct typing?

I'm trying to create a test for my scheduled worker and the default typing for a scheduled worker seems to work like this:

async scheduled(event: ScheduledEvent, env: Env, ctx: ExecutionContext): Promise<void> {
        console.log('This is a scheduled event');
    },

async scheduled(event: ScheduledEvent, env: Env, ctx: ExecutionContext): Promise<void> {
        console.log('This is a scheduled event');
    },

async scheduled(event: ScheduledEvent, env: Env, ctx: ExecutionContext): Promise<void> {
        console.log('This is a scheduled event');
    },

async scheduled(event: ScheduledEvent, env: Env, ctx: ExecutionContext): Promise<void> {
        console.log('This is a scheduled event');
    },

When I want to call this

scheluded

scheluded

scheluded

scheluded in my test I did this:

it("scheduled event logs 'This is a scheduled event'", async () => {
            const controller = createScheduledController({
                scheduledTime: new Date(1000),
                cron: "30 * * * *",
            });
            const ctx = createExecutionContext();
            await worker.scheduled(controller, env, ctx);
            await waitOnExecutionContext(ctx);
            expect(ctx.log).toMatchInlineSnapshot(`"This is a scheduled event"`);
        });

it("scheduled event logs 'This is a scheduled event'", async () => {
            const controller = createScheduledController({
                scheduledTime: new Date(1000),
                cron: "30 * * * *",
            });
            const ctx = createExecutionContext();
            await worker.scheduled(controller, env, ctx);
            await waitOnExecutionContext(ctx);
            expect(ctx.log).toMatchInlineSnapshot(`"This is a scheduled event"`);
        });

it("scheduled event logs 'This is a scheduled event'", async () => {
            const controller = createScheduledController({
                scheduledTime: new Date(1000),
                cron: "30 * * * *",
            });
            const ctx = createExecutionContext();
            await worker.scheduled(controller, env, ctx);
            await waitOnExecutionContext(ctx);
            expect(ctx.log).toMatchInlineSnapshot(`"This is a scheduled event"`);
        });

it("scheduled event logs 'This is a scheduled event'", async () => {
            const controller = createScheduledController({
                scheduledTime: new Date(1000),
                cron: "30 * * * *",
            });
            const ctx = createExecutionContext();
            await worker.scheduled(controller, env, ctx);
            await waitOnExecutionContext(ctx);
            expect(ctx.log).toMatchInlineSnapshot(`"This is a scheduled event"`);
        });

The typing seems to want an

ScheduledEvent

ScheduledEvent

ScheduledEvent

ScheduledEvent but I didn't find anyway to mock those. The only related mocking function seems to be

createScheduledController

createScheduledController

createScheduledController

createScheduledController but it's type is

 ScheduledController

ScheduledController

 ScheduledController

ScheduledController which is similiar but not the same.

O

onnimonni•4/13/24, 7:17 PM

Second question is that can I somehow test the side effects of the function like what it logs?

The scheduled functions don't return anything so testing the return values is impossible

O

onnimonni•4/13/24, 7:24 PM

Well I was able to fix this by allowing either

ScheduledController

ScheduledController

ScheduledController

ScheduledController or

ScheduledEvent

ScheduledEvent

ScheduledEvent

ScheduledEvent typing in the scheduled event and by following this stackoverflow answer on testing the logging: https://stackoverflow.com/questions/76042978/in-vitest-how-do-i-assert-that-a-console-log-happened

Stack Overflow

In Vitest, how do I assert that a console.log() happened?

The question's in the title. With Jest it was console.log = jest.fn(). How do I get and analyse the console output of the code I'm testing?

is there any difference between scheduler.wait and

};

export const sleep = (ms: number): Promise<void> => {
    return new Promise<void>((resolve) => setTimeout(resolve, ms));
};

export const sleep = (ms: number): Promise<void> => {

export const sleep = (ms: number): Promise<void> => {
