Problem: the hexagonal refactor churns the backend tree for nine more phases; the UI delivery stack (web/ SPA, cmd/desktop Wails wrapper, compose/web image) must move to its own repo first so doc/layout rewrites land once on a backend-only tree. Change: - New repo git.hubris.network/dtoro/oikos-web (v0.33.0): web/, desktop/ (updateURL repointed to oikos-web releases), compose/, own CI (web + desktop jobs), own deploy script (CI-green gate, TOCTOU guard, version-tagged images, prune-to-3), own webhook receiver on :9798 + launchd unit, own compose project publishing the same 8091:80. - Cutover executed on mac-mini in order: oikos stack's web service stopped+removed, oikos-web project brought up on 8091; outer Caddy untouched (targets the published port) — serving + Authentik flow + /wails 404 quirk verified post-cutover. - Stripped from oikos: web/, cmd/desktop/, compose/web/, desktop CI workflow, ci.yml web job, Makefile ui/desktop/desktop-package/install targets, the compose web service, oikos-web from deploy.sh's fallback prune list; wails + go-keyring dropped from go.mod, vendor synced. - README / CONTRIBUTING / AGENTS.md / .agents dev+operations docs now point at the new repo; mbse + mascot design docs carry a path note. Risk: production SPA serving depends on the new pipeline now; rollback is versioned-image re-up of the old web service from a pre-split checkout (port 8091). Desktop builds installed before the split still check dtoro/oikos releases — one manual reinstall, noted in the oikos-web release notes. Verification: go vet, make test (race), make generate-check, golangci (no new findings; baseline down 400→365); post-cutover curls — localhost:8091 200, /wails/runtime.js 404, outer Caddy 302 Authentik.

# p-limit
|
|
|
|
> Run multiple promise-returning & async functions with limited concurrency
|
|
|
|
## Install
|
|
|
|
```
|
|
$ npm install p-limit
|
|
```
|
|
|
|
## Usage
|
|
|
|
```js
|
|
const pLimit = require('p-limit');
|
|
|
|
const limit = pLimit(1);
|
|
|
|
const input = [
|
|
limit(() => fetchSomething('foo')),
|
|
limit(() => fetchSomething('bar')),
|
|
limit(() => doSomething())
|
|
];
|
|
|
|
(async () => {
|
|
// Only one promise is run at once
|
|
const result = await Promise.all(input);
|
|
console.log(result);
|
|
})();
|
|
```
|
|
|
|
## API
|
|
|
|
### pLimit(concurrency)
|
|
|
|
Returns a `limit` function.
|
|
|
|
#### concurrency
|
|
|
|
Type: `number`\
|
|
Minimum: `1`\
|
|
Default: `Infinity`
|
|
|
|
Concurrency limit.
|
|
|
|
### limit(fn, ...args)
|
|
|
|
Returns the promise returned by calling `fn(...args)`.
|
|
|
|
#### fn
|
|
|
|
Type: `Function`
|
|
|
|
Promise-returning/async function.
|
|
|
|
#### args
|
|
|
|
Any arguments to pass through to `fn`.
|
|
|
|
Support for passing arguments on to the `fn` is provided in order to be able to avoid creating unnecessary closures. You probably don't need this optimization unless you're pushing a *lot* of functions.
|
|
|
|
### limit.activeCount
|
|
|
|
The number of promises that are currently running.
|
|
|
|
### limit.pendingCount
|
|
|
|
The number of promises that are waiting to run (i.e. their internal `fn` was not called yet).
|
|
|
|
### limit.clearQueue()
|
|
|
|
Discard pending promises that are waiting to run.
|
|
|
|
This might be useful if you want to teardown the queue at the end of your program's lifecycle or discard any function calls referencing an intermediary state of your app.
|
|
|
|
Note: This does not cancel promises that are already running.
|
|
|
|
## FAQ
|
|
|
|
### How is this different from the [`p-queue`](https://github.com/sindresorhus/p-queue) package?
|
|
|
|
This package is only about limiting the number of concurrent executions, while `p-queue` is a fully featured queue implementation with lots of different options, introspection, and ability to pause the queue.
