How to save build files (React) using Github Actions - reactjs

Question

I am trying to build react code using github actions.
But after successfully building the files i want to save it in a particular location say "build" folder in the repo.
I am currently able to build the files but not save them in the repo

Answer 1

If you would like to try and commit your build artifacts back to the repository yourself in a workflow see the following answer for how to prepare the repository and git config.
Push to origin from GitHub action
Alternatively, you might find create-pull-request action useful for this use case. It will commit changes to the Actions workspace to a new branch and raise a pull request. So if you call create-pull-request action after creating your artifacts during a workflow, you can have that change raised as a PR for you to review and merge.
For example:
on: release
name: Update Version
jobs:
createPullRequest:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout#v2
...
(your build steps)
...
- name: Create Pull Request
uses: peter-evans/create-pull-request#v2
with:
token: ${{ secrets.GITHUB_TOKEN }}
commit-message: Add build artifact
title: Add build artifact

I just used https://github.com/s0/git-publish-subdir-action and it worked great. It just dumps files from a given folder into a branch. Here's an example workflow file that worked for me:
name: Build Data
on:
push:
branches: [ master ]
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout#v2
- name: Set up Python 3.x
uses: actions/setup-python#v2
with:
python-version: '3.x'
- name: Install dependencies
run: |
python -m pip install --upgrade pip
pip install -r tools/requirements.txt
- name: Run python script
run: python tools/data_builder.py
# THIS IS WHERE THE DATA IS PUBLISHED TO A BRANCH
- name: Deploy
uses: s0/git-publish-subdir-action#master
env:
REPO: self
BRANCH: data_build
FOLDER: tools/data_build
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
