3.52.6
(fix): Fix TypeScript generator crash when discriminated union discriminant values start
with digits (e.g., “1foo”, “1bar”). The generated code now prefixes such identifiers
with an underscore to produce valid TypeScript.
3.52.5
(fix): Fix Edge Runtime compatibility warning in Next.js. The runtime detection code
previously used process.versions.node directly, which caused Next.js bundlers
(Turbopack/webpack) to emit “A Node.js API is used which is not supported in
the Edge Runtime” warnings during static analysis, even though the code path was
guarded by an Edge Runtime check. The fix assigns process to a local variable
first, preventing bundlers from flagging the indirect property access.
3.52.4
(fix): Fix publint warning for ambiguous types in package.json exports. Remove the top-level
types condition from export entries in package.json so that import and require
conditions each resolve to their own correctly-typed declaration file (.d.mts for ESM,
.d.ts for CJS). This eliminates the publint warning about CJS types being used when
resolving with the “import” condition.
3.52.3
(fix): Handle nullable header types by converting null to undefined. HTTP headers
don’t have a “null” concept — they’re either present with a value or absent.
When a header’s type is nullable (explicitly via nullable: true in the spec),
the generated code now wraps the value with ?? undefined to ensure null values
are treated as “don’t send the header” instead of causing type errors.
3.52.2
(fix): Fix biome formatting not being applied in github output mode. The generator was calling
checkFix() (biome) without first installing biome, causing formatting to silently fail.
Now installs checkFix dependencies when tools are not globally available, matching the
existing behavior in downloadFiles mode.
3.52.1
(feat): Add JSDoc availability annotations for SDK endpoint methods. Endpoints marked as
deprecated in the Fern definition now generate a @deprecated JSDoc tag, causing
IDEs to show strikethrough and deprecation warnings. Endpoints marked as in-development
or pre-release generate a @beta JSDoc annotation. This applies to all endpoint types
(default, file download, and streaming).
