jsr-exports-lint

library0.4.2jsnpmunverified

A linting tool for validating the `exports` field in JSR's `jsr.json` manifest files, designed to be used as a build hook in `tsdown` or `unbuild`. Current stable version is 0.4.2. Released under MIT license with active development. Key differentiator: unlike `publint` which lints npm `package.json` exports, this tool specifically targets JSR's `jsr.json` exports, making it essential for library authors distributing via both npm and JSR. It fully supports TypeScript and requires Node >= 20. The lint runs after the build is done, checking that all exported entries match the actual built files.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

lintJsrExports

✓ import { lintJsrExports } from 'jsr-exports-lint/tsdown'

✗ import { lintJsrExports } from 'jsr-exports-lint'

Must import from subpath '/tsdown' for tsdown; from '/unbuild' for unbuild.

lintJsrExports

✓ import { lintJsrExports } from 'jsr-exports-lint/unbuild'

✗ import { lintJsrExports } from 'jsr-exports-lint'

Use '/unbuild' subpath when integrating with unbuild.

lintJsrExports

✓ const { lintJsrExports } = require('jsr-exports-lint/tsdown')

✗ const lintJsrExports = require('jsr-exports-lint')

CommonJS supported but requires subpath import.

Demonstrates the simplest setup for tsdown using the default jsr.json path.

// Install: npm install --save-dev jsr-exports-lint // tsdown.config.ts import { defineConfig } from 'tsdown' import { lintJsrExports } from 'jsr-exports-lint/tsdown' export default defineConfig({ entry: ['./src/index.ts', './src/features/a.ts'], publint: true, dts: true, hooks: { 'build:done': lintJsrExports() } }) // Run: npx tsdown build

Known issues

breakingPackage renamed in v0.2.0 from 'tsdown-jsr-exports-lint' to 'jsr-exports-lint'. Old imports break.

fix

Update import paths from 'tsdown-jsr-exports-lint' to 'jsr-exports-lint'.

affects: >=0.2.0

deprecatedSupport for tsdown <0.9.6 and unbuild <1.0.0 was dropped.

fix

Upgrade tsdown to >=0.9.6 and unbuild to >=1.0.0.

affects: >=0.2.0

gotchaThe lintJsrExports function must be called (invoked) in the hook, not just passed as a reference.

fix

Use hooks: { 'build:done': lintJsrExports() } — with parentheses.

affects: all

Errors

Common errors & fixes

Error: Cannot find module 'jsr-exports-lint'

Importing from the package root instead of the subpath.

fix

Import from 'jsr-exports-lint/tsdown' or 'jsr-exports-lint/unbuild'.

Error: 'undefined' is not a function (evaluating 'lintJsrExports()')

Passing lintJsrExports as a reference without calling it.

fix

Call it: hooks: { 'build:done': lintJsrExports() }.

TypeError: (0 , _jsr_exports_lint_tsdown.lintJsrExports) is not a function

Using default import instead of named import.

fix

Use named import: import { lintJsrExports } from 'jsr-exports-lint/tsdown'.
