Added availability to create segments on contacts lists and make campaigns over it

Closes #310


Summary by cubic

Adds contact segmentation so teams can target subsets of a contact book and see exact audience counts in campaigns.

  • New Features

    • Manage segments per contact book: create, edit, delete with rules (equals, contains, is set, is not set) and live contact counts.
    • Filter contact lists and exports by segment; invalid segment URLs auto-reset.
    • Campaign editor: pick a segment (resets on contact book change) and see a live audience badge; campaign details show segment and recipient count; getCampaign now includes contactSegment.
    • Backend: listSegments, createSegment, updateSegment, deleteSegment, getCampaignAudience; contacts APIs accept segmentId; campaign updates accept contactSegmentId with contact book validation; send/schedule/batching compute audience and totals using segment filters.
  • Migration

    • Adds ContactSegment table and Campaign.contactSegmentId. Run Prisma migrations to apply the new schema and indexes.

Written for commit 7419987. Summary will update on new commits.

Walkthrough

Campaign editing now supports selecting a contact segment and displaying its audience count. Campaign details display the selected audience name and count. Campaign sending, scheduling, and batch processing use shared segment-aware audience queries. Campaign audience context now resolves contact-book variables and optional segment filters in one helper.

Suggested reviewers: kmkoushik

Priority: ➖ Normal

Change: Feature

Merge Risk: 🟡 Moderate · up to 74199

Campaigns can now target a contact segment. If a user changes the segment and schedules immediately, the campaign may be scheduled for the previously selected audience and send to the wrong recipients. Block scheduling until the segment change is saved before merging.

Explanation

Issue #310 requires segments based on custom contact fields, multiple segments per contact book, and campaign delivery to a selected subset. The PR adds ContactSegment CRUD scoped to a contact book, supports equals, contains, isSet, and isNotSet, validates and normalizes custom fields, and calculates segment counts. Contact queries and exports accept segmentId. Campaign updates validate the segment and contact book. Audience counts, sending, scheduling, and batch processing apply the segment filter. The unit tests cover normalization, matching, and descriptions.

Full details: Out of Scope Changes check

Explanation

The migration and schema changes support segment persistence. The contact-book UI, contact-list and export filters, campaign selector, audience display, API procedures, campaign validation, and sending changes implement the segmentation objective. The tests cover the new segment helpers. No unrelated change is demonstrated.

47-47: Use the ~/ alias for this new src import.

contact-segments-manager lives under apps/web/src, so this new import should follow the repo alias convention instead of adding another relative path.

As per coding guidelines, apps/web/src/**/*.{ts,tsx} should "Use the ~/ alias for imports from src in apps/web (e.g., import { x } from "~/utils/x")".

8-77: Add one regression test for the server-side filter path.

These tests only cover the in-memory helpers. The new audience counts and contact filtering now depend on buildContactSegmentWhere(), so a mismatch in the Prisma translation can still ship unnoticed. Please add at least one server-side test that exercises isSet / isNotSet through the query path.

In `@apps/web/src/app/`(dashboard)/contacts/[contactBookId]/contact-list.tsx:
- Around line 86-89: The URL-stored segmentId must be cleared when the selected
segment no longer exists: after the segmentsQuery
(api.contacts.listSegments.useQuery) returns, check whether the current
segmentId from useUrlState("segment") exists in segmentsQuery.data; if it does
not, call setSegmentId("") (or undefined per useUrlState expectation) to remove
the invalid filter so the contacts/export queries stop sending the deleted id;
implement this check in a useEffect that depends on segmentsQuery.data and
segmentId and reference segmentId, setSegmentId, and segmentsQuery to locate the
code to update.

In
`@apps/web/src/app/`(dashboard)/contacts/[contactBookId]/contact-segments-manager.tsx:
- Around line 168-182: The early return when contactBookVariables.length === 0
hides the segments list; remove that return and instead keep rendering the
segments management UI (the list/rendering code for existing segments) while
showing the informational Card (the existing
Card/CardHeader/CardTitle/CardContent snippet) as a warning/notice; only disable
or hide the segment-creation controls (e.g., the Create/Manage button or
createSegment handler) when contactBookVariables is empty so saved segments
(referenced as segments or whatever list variable the component renders) remain
visible and deletable. Ensure you update any create-segment button or form
(CreateSegmentButton, onCreateSegment, or similar) to be disabled when
contactBookVariables.length === 0 rather than preventing the entire component
from rendering.

In `@apps/web/src/server/service/contact-segment-filter.ts`:
- Around line 44-58: The isSet/isNotSet Prisma filters currently use
Prisma.JsonNull which only matches explicit JSON nulls; update the case handling
in contact-segment-filter (the "isSet" and "isNotSet" branches that build the
properties filter for path) to use Prisma.DbNull instead (for isNotSet use
equals: Prisma.DbNull or for isSet use NOT: { properties: { path, equals:
Prisma.DbNull } } / for the negated case use not: Prisma.DbNull) so missing JSON
keys (SQL NULL) are matched the same way the in-memory matcher does; adjust the
NOT/negation logic accordingly in the code that constructs the properties filter
for path.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Wait for segment persistence before scheduling.

ScheduleCampaign remains available while the editor's segment update is pending. The schedule mutation can run first. The scheduling service reads the campaign from the database, so it can use the previous contactSegmentId and target the wrong audience.

Disable scheduling while the campaign update is pending, or make scheduling await the segment update.
