Branch

Source: src/Prisma/Branch.ts

A Prisma project branch for preview-class databases and compute resources.

Standalone Branch resources always have the preview role. Promotion changes only the default branch; Alchemy restores the previous default before deleting a promoted branch.

Creating a Branch

const branch = yield* Prisma.Branch("preview", {
  project: project.projectId,
  gitName: "feature/search", // optional — omitted, a stable name is generated
});

branch.role;      // "preview"
branch.isDefault; // false

Promoting a Branch

const release = yield* Prisma.Branch("release", {
  project,
  gitName: "release/next",
  isDefault: true,
});

release.role;      // still "preview"
release.isDefault; // true
