rollup-timer

library0.3.4jsnpmunverified

Times Rollup plugins by monkey-patching plugin API functions. Version 0.3.4 is stable with no recent updates; it works with Rollup <1 and is incompatible with rollup-plugin-commonjs. Differentiator: simple drop-in timing for Rollup builds, with support for both promise and stream-based rollup invocations.

Verified usage

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

time

✓ import time from 'rollup-timer'

✗ const time = require('rollup-timer')

Default export is the time() function; CommonJS require returns the module object, not the function directly.

RollupTimer

✓ import { RollupTimer } from 'rollup-timer'

✗ import RollupTimer from 'rollup-timer'

RollupTimer is a named export, not default.

time (named import)

✓ import * as timer from 'rollup-timer'; timer.default()

✗ import { time } from 'rollup-timer'

There is no named export 'time'; using named import incorrectly yields undefined.

Monkey-patches Rollup to time plugin execution and outputs timing information.

const rollup = require('rollup'); const time = require('rollup-timer').default; time(rollup); const options = { input: 'src/index.js', plugins: [] }; rollup.rollup(options).then(bundle => bundle.write({ file: 'dist/bundle.js' })).catch(err => console.error(err));

Debug

Known issues

gotcharollup-timer is incompatible with rollup-plugin-commonjs; timings for that plugin will be incomplete.

fix

Avoid using rollup-timer with rollup-plugin-commonjs, or expect inaccurate timing data.

affects: >=0.0.0

deprecatedThe package monkey-patches internal Rollup API and may break with future Rollup versions. Last updated for Rollup 0.x; not tested with Rollup 1+.

fix

Consider using Rollup's built-in timing support or other profiling tools.

affects: >=0.0.0

gotchaPlugin 'name' property required for readable reports; if a plugin lacks name, the report falls back to numeric index.

fix

Ensure plugins provide a 'name' property; submit PRs to plugin authors if missing.

affects: >=0.0.0

Errors

Common errors & fixes

TypeError: (0 , _rollupTimer2.default) is not a function

Using named import 'time' instead of default import.

fix

Use 'import time from 'rollup-timer''

time is not a function

Incorrectly importing as named export or using CommonJS without .default.

fix

Use 'const time = require('rollup-timer').default'
