Docs for Prisma ORM v6.16.0 #7096
Conversation

WalkthroughDocs updated to document Prisma ORM's Rust‑free mode (GA notes v6.15.0+/v6.16.0): generator examples now use provider = "prisma-client-js" (or "prisma-client"), often include output and engineType = "client"; driver‑adapter guidance, links, and a PostgreSQL‑extensions migration workflow were revised; preview badges/preview lists were removed or adjusted.

69-72: Version claim: please verify GA/version wording.Docs currently state “No Rust engine” was introduced in v6.7.0 (later GA status may differ). If you intend to communicate GA in v6.15.0, please confirm in release notes and adjust phrasing to avoid confusion. For example: “Introduced in v6.7.0, GA in v6.15.0 …”. (prisma.io)
81-84: Driver adapters note looks good.Clear and correctly linked for the no-Rust path.
content/200-orm/100-prisma-schema/10-overview/03-generators.mdx (3)
48-49: Confirm GA/version statement.If you’re asserting GA “as of v6.15.0”, please verify and align with the “No Rust engine” page and release notes, which still anchor the feature’s introduction to v6.7.0. Adjust wording if needed (e.g., “Introduced in 6.7.0, GA in 6.15.0”). (prisma.io, newreleases.io)
60-66: These two notes are accurate for no-Rust.
- Driver adapters required.
- binaryTargets obsolete.
144-146: Fence change to “terminal” looks fine.No issues with the code block update.

7-7: GA claim needs verification (docs still show Preview path).Official docs currently describe the Rust‑free path as available since v6.7.0 via the

14-35: LGTM! Well-structured documentation update for Prisma ORM's Rust-free mode.The updated tip section clearly explains the new GA configuration for running Prisma ORM without Rust binaries. The content accurately reflects the transition from preview features to the stable
engineType = "client"approach, with proper version references and helpful links to additional resources.
248-248: LGTM! Consistent database connection configuration guidance.The repeated pattern of ensuring proper database connection configuration across different database providers (PostgreSQL, PlanetScale, Neon) is consistent and helpful for users following the deployment guides.
Also applies to: 403-403, 533-533
237-237: Script to verify PostgreSQL adapter link added; awaiting results.content/200-orm/050-overview/500-databases/200-database-drivers.mdx (2)
68-71: PlanetScale link still targets a “Preview” anchor; confirm final slug.Neon’s link omits “-preview” while PlanetScale uses “-preview”. Verify the current headings/anchors for 6.16 docs and update if PlanetScale is no longer marked Preview.
Suggested (only if the anchor changed):
-- [PlanetScale](/orm/overview/databases/planetscale#how-to-use-the-planetscale-serverless-driver-with-prisma-orm-preview) +- [PlanetScale](/orm/overview/databases/planetscale#how-to-use-the-planetscale-serverless-driver-with-prisma-orm)Reference for current anchor shows “(Preview)”. (prisma.io)
151-152: “Preview feature” wording may be outdated; verify status and adjust.If driver adapters are still Preview in 6.16.0, keep this wording; if not, drop “Preview” here for consistency with the rest of the page.
Example edit (only if GA):
-Since Prisma 5.9.0, when using the driver adapters Preview feature along with a [custom output path for Prisma Client]... +Since Prisma 5.9.0, when using driver adapters along with a [custom output path for Prisma Client]...Note: Current public docs still label several adapter pages as “Preview”.

7-7: Verify GA claim for “no Rust engine” in v6.16.0.Live docs still describe this as available since v6.7.0 with Preview feature flags, not GA. Please confirm the release notes for 6.16.0 before publishing this GA statement. If GA isn’t landing in 6.16.0, revert to the current wording (“As of v6.7.0…”) and keep the Preview flow. Sources: “No Rust engine” docs and changelog/blog. (prisma.io)
-As of [v6.16.0](https://pris.ly/release/6.16.0), usage of Prisma ORM without ... +As of v6.7.0, you can use Prisma ORM without ...
27-27: Align minimum version with reality (6.15.0 vs 6.7.0 vs 6.16.0).If GA truly lands in 6.16.0 and requires
engineType = "client", set this to “v6.16.0 (or later)”. If not, keep “v6.7.0 (or later)” to match the current Preview docs. (prisma.io)-- Prisma ORM v6.15.0 (or later) +// If GA: Prisma ORM v6.16.0 (or later) +// If Preview: Prisma ORM v6.7.0 (or later)
39-46: LGTM — regenerate step.Command and phrasing look good.
51-92: Adapter package names look correct.PostgreSQL, SQLite, D1, MySQL/MariaDB, PlanetScale, MSSQL, CockroachDB (via pg), and Neon match current docs. (prisma.io)
98-210: Examples compile and align with custom output path.All imports use
./generated/prisma, consistent withoutput = "../generated/prisma". Neon, PlanetScale, and D1 snippets match adapter usage in live docs. (prisma.io)
216-219: Good separation for “older versions (Preview)”.Clear guidance to keep Preview instructions isolated from the GA/modern flow.
415-418: LGTM — closing details block.Structure and wording are fine.

136-137: Good: explicit call-out for Vercel Postgres → Neon adapter.Nice clarity that Vercel Postgres requires
@prisma/adapter-neon. ✅
269-270: PlanetScale link anchor still says “preview” — confirm status.PlanetScale serverless driver docs remain marked Preview today; the anchor is correct. Keep as-is unless GA is announced. (prisma.io)
391-392: Neon cross-link matches Neon page (but ensure Preview vs GA is consistent).If you revert Neon to Preview in its page, this cross-link remains valid. (prisma.io)
45-56: Edge compatibility note is accurate.pg isn’t supported in Vercel Edge; using an edge-compatible driver with an adapter is the right guidance.
508-527: Fluid example looks good.Using

17-21: Do not instruct to set engineType="client"; keep Preview bullets.Official docs list valid engineType values as only "binary" or "library"; the Rust‑free flow uses preview flags and explicitly says “no engineType field”. Adjust bullets accordingly.
