This guide aims to help you migrating to webpack 5 when using webpack directly. If you are using a higher level tool to run webpack, please refer to the tool for migration instructions.
Preparations
Webpack 5 requires at least Node.js 10.13.0 (LTS), so make sure you upgrade your Node.js if you're still running an older one.
Upgrade webpack 4 and its plugins/loaders
Upgrade
webpack
4 to the latest available version.When using webpack >= 4, upgrading to the latest webpack 4 version should not require additional guidance.
Microsoft office. If you are using webpack version less than 4 please see the webpack 4 migration guide.
Upgrade
webpack-cli
to the latest available version (when used)Upgrade all used Plugins and Loaders to the latest available version
Some Plugins and Loaders might have a beta version that has to be used in order to be compatible with webpack 5.
Make sure your build has no errors or warnings
There might be new errors or warnings because of the upgraded versions of webpack
, webpack-cli
, Plugins and Loaders. Keep an eye for deprecation warnings during the build.
You can invoke webpack
this way to get stack traces for deprecation warnings to figure out which Plugins and Loaders are responsible.

As webpack 5 removes all deprecated features, make sure there's no webpack deprecation warnings during the build in order to proceed.
Make sure to use mode
Set mode
to either production
or development
to make sure that corresponding defaults are set.
Update outdated options
Update the following options to their new version (if used):
optimization.hashedModuleIds: true
→optimization.moduleIds: 'deterministic'
optimization.namedChunks: true
→optimization.chunkIds: 'named'
optimization.namedModules: true
→optimization.moduleIds: 'named'
NamedModulesPlugin
→optimization.moduleIds: 'named'
NamedChunksPlugin
→optimization.chunkIds: 'named'
HashedModuleIdsPlugin
→optimization.moduleIds: 'deterministic'
optimization.noEmitOnErrors: false
→optimization.emitOnErrors: true
optimization.occurrenceOrder: true
→optimization: { chunkIds: 'total-size', moduleIds: 'size' }
optimization.splitChunks.cacheGroups.vendors
→optimization.splitChunks.cacheGroups.defaultVendors
Compilation.entries
→Compilation.entryDependencies
serve
→serve
is removed in favor ofDevServer
Test webpack 5 compatibility
Try to set the following options in your webpack 4 configuration and check if build still works correctly.
You have to remove these options again when upgrading your configuration for webpack 5.
tipwebpack 5 removes these options from the configuration schema and will always use false
.
Upgrade webpack to 5
Now let's upgrade webpack to version 5:
npm:
npm install webpack@latest
Yarn:
yarn add webpack@latest
Clean up configuration
Consider removing
optimization.moduleIds
andoptimization.chunkIds
from your webpack configuration. The defaults could be better, because they support long term caching inproduction mode
and debugging indevelopment
mode.Linguist 1 9 words. When using
[hash]
placeholder in webpack configuration, consider changing it to[contenthash]
. It is not the same, but proven to be more effective.If you are using Yarn's PnP and the
pnp-webpack-plugin
, we have good news: it is supported by default now. You have to remove it from the configuration.If you are using
IgnorePlugin
with a regular expression as argument, it takes anoptions
object now:new IgnorePlugin({ resourceRegExp: /regExp/ })
.If you are using something like
node.fs: 'empty'
replace it withresolve.fallback.fs: false
.If you are using
watch: true
in webpack Node.js API, remove it. There's no need to set it as it's indicated by the compiler method you call, eithertrue
forwatch()
orfalse
forrun()
.If you have
rules
defined for loading assets usingraw-loader
,url-loader
, orfile-loader
, please use Asset Modules instead as they're going to be deprecated in near future.If you have
target
set to a function, update it tofalse
and apply that function withinplugins
option. See example below:
If you were using WebAssembly via import, you should follow this two step process:
- Enable the deprecated spec by setting
experiments.syncWebAssembly: true
, to get the same behavior as in webpack 4. - After successful migration to webpack 5, change the
experiments
value toexperiments: { asyncWebAssembly: true }
to use the up-to-date spec for WASM integration.
Reconsider optimization.splitChunks
:
- It's recommended to use either the defaults or
optimization.splitChunks: { chunks: 'all' }
. - When using a custom configuration, drop
name: false
and replacename: string | function
withidHint: string | function
. - It was possible to turn off the defaults by setting
optimization.splitChunks: { default: false, vendors: false }
. We don't recommend doing this, but if you really want to get the same effect in webpack 5:optimization.splitChunks: { default: false, defaultVendors: false }
.
Consider removing defaults:
- Using
entry: './src/index.js'
: you can omit it, that's the default. - Using
output.path: path.resolve(__dirname, 'dist')
: you can omit it, that's the default. - Using
output.filename: '[name].js'
: you can omit it, that's the default.
Need to support an older browser like IE 11?
- By default, webpack 5 will use your
browserslist
config to decide which code style to emit for the runtime code. - Without a
browserslist
webpack's runtime code uses ES2015 syntax (e.g., arrow function) to build smaller bundles. If your build targets environments that don't support ES2015 syntax (like IE11), you'll need to settarget: ['web', 'es5']
to use ES5 syntax. - For Node.js, builds include the supported Node.js version in the
target
option and webpack will automatically figure out which syntax is supported, e.g.target: 'node8.6'
.
Cleanup the code
Using /* webpackChunkName: '..' */
Make sure to understand the intention:
- The chunk's name here is intended to be public.
- It's not a development-only name.
- Webpack will use it to name files in production and development modes.
- Webpack 5 will automatically assign useful file names in
development
mode even when not usingwebpackChunkName
.
Using named exports from JSON modules
This is not supported by the new specification and you will get a warning. Instead of:
use:
Cleanup the build code
- When using
const compiler = webpack(..);
, make sure to close the compiler after using it:compiler.close(callback);
.- This doesn't apply to the
webpack(.., callback)
form which automatically closes. - This is optional if you use webpack in watching mode until the user ends the process. The idle phases in watch mode will be used for this kind of work.
- This doesn't apply to the
Run a single build and follow advises
Please make sure to read the building errors/warnings carefully. If there is no corresponding advise, please create an issue and we will try to resolve it.
Repeat the following steps until you solved at least level 3 or 4:
Level 1: Schema validation fails.
Configuration options have changed. There should be a validation error with a
BREAKING CHANGE:
note, or a hint of which option should be used instead.Level 2: Webpack exits with an error.
The error message should tell you what needs to be changed.
Level 3: Build Errors.
The error message should have a
BREAKING CHANGE:
note.Level 4: Build Warnings.
The warning message should tell you what can be improved.
Level 5: Runtime Errors.
This is tricky. You probably have to debug to find the problem. A general advise is difficult here. But we do list some common advices below regarding Runtime Errors:
process
is not defined.- webpack 5 does no longer include a polyfill for this Node.js variable. Avoid using it in the frontend code.
- Want to support browser usage? Use the
exports
orimports
package.json field to use different code depending on the environment.- Also use the
browser
field to support older bundlers. - Alternative: Wrap code blocks with the
typeof process
checks. Note that this will have a negative impact on the bundle size.
- Also use the
- Want to use environment variables with
process.env.VARIABLE
? You need to use theDefinePlugin
orEnvironmentPlugin
to define these variables in the configuration.- Consider using
VARIABLE
instead and make sure to checktypeof VARIABLE ! 'undefined'
too.process.env
is Node.js specific and should be avoided in frontend code.
- Consider using
- 404 errors pointing to URLs containing
auto
- Not all ecosystem tooling is ready for the new default automatic
publicPath
viaoutput.publicPath: 'auto'
- Use a static
output.publicPath: '
instead.
- Use a static

Level 6: Deprecation Warnings.
You probably get a lot of deprecation warnings. This is not directly a problem. Plugins need time to catch up with core changes. Please report these deprecations to the plugins. These deprecations are only warnings and the build will still work with only minor drawbacks (like less performance).
- You can hide deprecation warnings by running node with
--no-deprecation
flag, e.g.:node --no-deprecation node_modules/webpack/bin/webpack.js
. This should only be a temporary workaround. - Plugins and Loaders contributors can follow the advises in the deprecation messages to improve the code.
- You can hide deprecation warnings by running node with
Level 7: Performance issues.
Usually, performance should improve with webpack 5, but there are also a few cases where performance gets worse.
And here are something you can do to improve the situation:
- Profile where the time is spend.
--profile --progress
displays a simple performance profile nownode --inspect-brk node_modules/webpack/bin/webpack.js
+chrome://inspect
/edge://inspect
(see profiler tab).- You can save these profiles to files and provide them in issues.
- Try using
--no-turbo-inlining
flag for better stack traces in some cases
- Time for building modules in incremental builds can be improved by reverting to unsafe caching like in webpack 4:
module.unsafeCache: true
- But this might affect the ability to handle some of the changes to the code base
- Full build
- Backward-compatibility layer for the deprecated features will usually have worse performance compared to the new features.
- Creating many warnings can affect build performance, even if they are ignored.
- Source Maps are expensive. Check
devtool
option in the documentation to see a comparison of the different options. - Anti-Virus protection might affect performance of the file system access.
- Persistent Caching can help to improve the repetitive full builds.
- Module Federation allows to split the application into multiple smaller builds.
- Profile where the time is spend.
Everything works?

Changes to internals
The changes to webpack internals such as: adding types, refactoring code and methods renaming are listed here for anyone interested. But they are not intended as a part of common use-case migration.
Module.nameForCondition
,Module.updateCacheModule
andModule.chunkCondition
are no longer optional.
getOptions method for Loaders
webpack 5 ships with built-in this.getOptions
method available in loader context. This is a breaking change for loaders that had been using getOptions
method from previously preferred schema-utils:
this.getOptions
is available since webpack 5- Instead of JSON5 it supports JSON as a query string:
?{arg:true}
→?{'arg':true}
. Using JSON5 should be considered and documented as deprecated in favor of JSON in the respective Loader's documentation. loader-utils
has specific behavior for parsing query strings (true
,false
andnull
won't be parsed asstring
but as a primitive value). This is no longer the case for the new built-inthis.getOptions
method, which uses nativequerystring
parsing (ships with Node.js). It is still possible to add custom behavior for these cases in the Loader's code after getting the options by usingthis.getOptions
method.- Schema argument is optional for the new
this.getOptions
method, but we strongly advise to add schema validation for your Loader's options. Thetitle
field in the schema, can be used to customize the validation error message e.g.'title': 'My Loader ooooptions'
will result in displaying errors this way:Invalid ooooptions object. My Loader has been initialised using an ooooptions object that does not match the API schema. - ooooptions.foo.bar.baz should be a string.
