Use custom build output folder when using create-react-app

Question

Facebook provides a create-react-app command to build react apps  When we run npm run build  we see output in  build folder       npm run build      Builds the app for production to the build folder  It correctly   bundles React in production mode and optimizes the build for the best   performance       The build is minified and the filenames include the hashes  Your app   is ready to be deployed    How can we use custom folder instead of  build for the output  Thanks

You can t change the build output folder name with the current configuration options   Moreover  you shouldn t  This is a part of the philosophy behind create-react-app  they say Convention over Configuration   If you really need to rename your folder  I see two options    Right after the build process finishes  write a command that copies the build folder content to another folder you want  For example you can try the copyfiles npm package  or anything similar  You could try to eject create-react-app and tweak the configuration      If you aren   t satisfied with the build tool and configuration choices  you can eject at any time  This command will remove the single build dependency from your project       Instead  it will copy all the configuration files and the transitive dependencies  Webpack  Babel  ESLint  etc  right into your project so you have full control over them  All of the commands except eject will still work  but they will point to the copied scripts so you can tweak them  At this point you   re on your own    However  it is important to note that this is a one-way operation  Once you eject  you can   t go back  You loose all future updates    Therefore  I d recommend you to not use a custom folder naming  if possible  Try to stick with the default naming  If not an option  try  1  If it still doesn t work for your specific use-case and you re really out of options - explore  2  Good luck

If you have arrived at this question three years after its initial posting because this is still a problem for you  consider backing this proposal to support a new BUILD PATH environment variable   https   github com facebook create-react-app pull 8986  From the proposal s documentation      By default  Create React App will output compiled assets to a  build directory adjacent to  src  You may use this variable to specify a new path for Create React App to output assets  BUILD PATH should be specified as a path relative to the root of your project    If this proposal is adopted  it would mean that customizing the output target for create-react-app becomes as simple as updating updating your build script      package json    scripts          build    BUILD PATH    dist  react-scripts build                     or adding a  env file to the root of your project      env BUILD PATH    dist

F  lix s answer is correct and upvoted  backed-up by Dan Abramov himself   But for those who would like to change the structure of the output itself  within the build folder   one can run post-build commands with the help of postbuild  which automatically runs after the build script defined in the package json file   The example below changes it from static  to user static   moving files and updating file references on relevant files  full gist here    package json       name    your-project      version    0 0 1              scripts          build    react-scripts build        postbuild      postbuild sh                      postbuild sh     bin bash    The purpose of this script is to do things with files generated by    create-react-app  after  build  is run    1  Move files to a new directory called  user       The resulting structure is  build user static  lt etc gt     2  Update reference on generated files from      static  lt etc gt        to      user static  lt etc gt      More details on  https   github com facebook create-react-app issues 3824    Browse into    build   directory cd build   Create    user   directory echo  1 4 Create  user  directory  mkdir user   Find all files  excluding  through  grep      -        - the newly created directory    user     - all content for the directory   static     Move all matches to the directory    user   echo  2 4 Move relevant files  find     grep -Ev          user      static        xargs -I   mv -v    user   Browse into    user   directory cd user   Find all files within the folder  not subfolders    Replace string  static   with  user static   on all files that match the  find      sed  requires one to create backup files on OSX  so we do that  echo  3 4 Replace file references  find   -type f -maxdepth 1   LC ALL C xargs -I   sed -i backup -e  s static  user static  g       Delete    backup  files created in the last process echo  4 4 Clean up  find   -name    backup  -type f -delete   Done

You can update the configuration with a little hack  under your root directory    npm run eject config webpack config prod js - line 61 - change path to    dirname         --your directory of choice--  config paths js - line 68 - update to resolveApp    --your directory of choice--     replace --your directory of choice-- with the folder directory you want it to build on  note the path I provided can be a bit dirty  but this is all you need to do to modify the configuration
