Use artifacts to share data between jobs in a workflow and store data once that workflow has completed.
PrerequisitesBefore you can complete this tutorial, you need to understand workflow artifacts. See Workflow artifacts.
Uploading build and test artifactsThe output of building and testing your code often produces files you can use to debug test failures and production code that you can deploy. You can configure a workflow to build and test the code pushed to your repository and report a success or failure status. You can upload the build and test output to use for deployments, debugging failed tests or crashes, and viewing test suite coverage.
You can use the upload-artifact
action to upload artifacts. When uploading an artifact, you can specify a single file or directory, or multiple files or directories. You can also exclude certain files or directories, and use wildcard patterns. We recommend that you provide a name for an artifact, but if no name is provided then artifact
will be used as the default name. For more information on syntax, see the actions/upload-artifact action.
For example, your repository or a web application might contain SASS and TypeScript files that you must convert to CSS and JavaScript. Assuming your build configuration outputs the compiled files in the dist
directory, you would deploy the files in the dist
directory to your web application server if all tests completed successfully.
|-- hello-world (repository)
| └── dist
| └── tests
| └── src
| └── sass/app.scss
| └── app.ts
| └── output
| └── test
|
This example shows you how to create a workflow for a Node.js project that builds the code in the src
directory and runs the tests in the tests
directory. You can assume that running npm test
produces a code coverage report named code-coverage.html
stored in the output/test/
directory.
The workflow uploads the production artifacts in the dist
directory, but excludes any markdown files. It also uploads the code-coverage.html
report as another artifact.

Configuring a custom artifact retention period
You can define a custom retention period for individual artifacts created by a workflow. When using a workflow to create a new artifact, you can use retention-days
with the upload-artifact
action. This example demonstrates how to set a custom retention period of 5 days for the artifact named my-artifact
:
- name: 'Upload Artifact' uses: actions/upload-artifact@v4 with: name: my-artifact path: my_file.txt retention-days: 5
- name: 'Upload Artifact'
uses: actions/upload-artifact@v4
with:
name: my-artifact
path: my_file.txt
retention-days: 5
The retention-days
value cannot exceed the retention limit set by the repository, organization, or enterprise.
You can use the actions/download-artifact
action to download previously uploaded artifacts during a workflow run.
Specify an artifact's name to download an individual artifact. If you uploaded an artifact without specifying a name, the default name is artifact
.
- name: Download a single artifact
uses: actions/download-artifact@v4
with:
name: my-artifact
You can also download all artifacts in a workflow run by not specifying a name. This can be useful if you are working with lots of artifacts.
- name: Download all workflow run artifacts
uses: actions/download-artifact@v4
If you download all workflow run's artifacts, a directory for each artifact is created using its name.
For more information on syntax, see the actions/download-artifact action.
Passing data between jobs in a workflowYou can use the upload-artifact
and download-artifact
actions to share data between jobs in a workflow. This example workflow illustrates how to pass data between jobs in the same workflow. For more information, see the actions/upload-artifact and download-artifact actions.
Jobs that are dependent on a previous job's artifacts must wait for the dependent job to complete successfully. This workflow uses the needs
keyword to ensure that job_1
, job_2
, and job_3
run sequentially. For example, job_2
requires job_1
using the needs: job_1
syntax.
Job 1 performs these steps:
math-homework.txt
.upload-artifact
action to upload the math-homework.txt
file with the artifact name homework_pre
.Job 2 uses the result in the previous job:
homework_pre
artifact uploaded in the previous job. By default, the download-artifact
action downloads artifacts to the workspace directory that the step is executing in. You can use the path
input parameter to specify a different download directory.math-homework.txt
file, performs a math calculation, and saves the result to math-homework.txt
again, overwriting its contents.math-homework.txt
file. As artifacts are considered immutable in v4
, the artifact is passed a different input, homework_final
, as a name.Job 3 displays the result uploaded in the previous job:
homework_final
artifact from Job 2.The full math operation performed in this workflow example is (3 + 7) x 9 = 90
.

echo The result is $value
The workflow run will archive any artifacts that it generated. For more information on downloading archived artifacts, see Downloading workflow artifacts.
Validating artifactsEvery time the upload-artifact action is used it returns an output called digest
. This is a SHA256 digest of the Artifact you uploaded during a workflow run.
When the download-artifact action is then used to download that artifact, it automatically calculates the digest for that downloaded artifact and validates that it matches the output from the upload-artifact step.
If the digest does not match, the run will display a warning in the UI and in the job logs.
To view the SHA256 digest, open the logs for the upload-artifact job or check in the Artifact output that appears in the workflow run UI.
