# New bounded context
|
|
|
|
A context is a business **capability**, not a user group — a user group is an actor
|
|
that may span contexts (ADR-0002). Check first whether the capability belongs in an
|
|
existing context; new contexts are rare.
|
|
|
|
Naming: domain contexts are **Dutch** (`registratie`, `herregistratie`); only
|
|
shared/reusable code is English. The context name is the ubiquitous language term.
|
|
|
|
## Steps
|
|
|
|
1. **Folders** — `src/app/<ctx>/{domain,application,infrastructure,ui}` (`contracts/`
|
|
only once it gets a wire seam). Empty layers can wait; don't scaffold placeholders.
|
|
2. **Path alias** — add `"@<ctx>/*": ["src/app/<ctx>/*"]` to `tsconfig.json` `paths`.
|
|
Aliases are direction statements; always import cross-context via the alias.
|
|
3. **eslint boundaries** (`eslint.config.mjs`) — dependencies point inward and
|
|
toward `shared` only. Copy the existing per-context block (the `brief` block is
|
|
the minimal leaf-context example) and:
|
|
- add a block for `src/app/<ctx>/**/*.ts` banning imports from every context it
|
|
may **not** depend on;
|
|
- add `@<ctx>/*` to the ban lists of `shared/**` and every context that must not
|
|
depend on the new one (grep the config for `@brief/*` to find all lists);
|
|
- the generic blocks (`domain/**` framework-free, `contracts/**` import-nothing,
|
|
ApiClient confinement, `ui/**` never imports `infrastructure`) match by glob
|
|
and cover the new context automatically.
|
|
4. **Route** — lazy child under the persistent shell in `app.routes.ts`:
|
|
|
|
```ts
|
|
{ path: '<ctx>', canActivate: [authGuard],
|
|
loadComponent: () => import('@<ctx>/ui/<ctx>.page').then(m => m.CtxPage) }
|
|
```
|
|
|
|
5. Build the first feature slice with the **new-feature** skill.
|
|
|
|
## Worked example
|
|
|
|
`src/app/brief/` — an independent leaf context (depends only on shared): see its
|
|
folder layout and its eslint block in `eslint.config.mjs`.
|
|
|
|
## Verify
|
|
|
|
```bash
|
|
npm run lint && npm run build
|
|
# prove the fence works: add a forbidden import (e.g. new ctx → @herregistratie/*),
|
|
# confirm lint fails, remove it.
|
|
```
