Bundling and Uploading a Theme
If you have customized a theme originally downloaded from the BigCommerce Theme Marketplace: Before you package your theme, make sure your theme directory includes all the dependencies that BigCommerce requires for submission.
Follow the link for your scenario:
If you downloaded a refreshed version of Stencil’s default Cornerstone theme: Run
If you downloaded a different Marketplace theme, and its version was lower than 1.10.0:
You must also run
jspm install in the theme directory.
stencil bundle and
stencil push commands do not check for the dependencies that these build systems install. So if those dependencies are missing, these commands will not immediately report errors. However, your resulting .zip file will not properly upload to BigCommerce, and will not run properly on a storefront.
Verify Directory and File Permissions
If you have added any new subdirectories or files to your base theme, verify that you have:
Set newly added directories to permission
Set newly added files to permission
Without these permissions, bundling your theme will fail, blocking its upload to BigCommerce.
Bundling Your Theme
Once you have verified the requirements above, you are ready to process and package your theme for upload to BigCommerce. Stencil CLI provides two options for creating a
.zip file that contains all of your theme’s essentials, while excluding redundant components. The options are either only bundling your theme, or bundling and pushing your theme. These options are available depending on how you’ve authorized your theme:
stencil bundle command is available for all themes, whether they were initialized using OAuth or Basic-Auth tokens. To use it, just enter the following on your command line:
bundle command will notify you of its progress and completion.
Check/Adjust Zipfile’s Size
Check the resulting
.zip file’s size before you proceed. The zipped bundle should be only a few megabytes. BigCommerce imposes a hard limit of 50 MB, and any file size approaching that is problematic. If your
.zip file fits comfortably within the size limit above, jump directly to Uploading Your Theme. However, if your
.zip file approaches or exceeds 50 MB, you must first use one of these procedures to restructure your theme to a size that’s manageable for upload to BigCommerce:
Bundle and Push
stencil push command is available only for themes that you have successfully initialized using an OAuth token (with
Themes:modify scope). This command bundles your theme and uploads it to the associated store, in one continuous process.
For further requirements and usage details, please see the Command-Line Upload in Uploading Your Theme below.
For file-size error diagnostics and workarounds, please Check/Adjust Zipfile’s Size above.
Software Requirements / Resolving Lint Errors
Only use the
stencil bundleor the
stencil pushcommand to process and package themes for submission. These commands generate
.zipfiles that match BigCommerce’s expected structure. They also generate metadata required for your theme to function properly.
Do not create
.zipfiles using general-purpose archiving software. The resulting files will trigger errors upon upload to BigCommerce.
Do not open a bundled theme
.zipfile to add, delete, rename, or update files. Doing so will make your theme unusable on the production store.
If bundling your theme triggers multiple lint errors related to the
bundle.jsfile, then your theme is missing the
.eslintignorefile. Please retrieve this file from the Stencil Cornerstone repo, then re-run
Uploading Your Theme
BigCommerce provides two alternatives for uploading a theme to its associated BigCommerce store. You can perform either a Control Panel Upload, or a Command Line Upload. These options are available depending on how you’ve authorized your theme:
Control-Panel Upload (OAuth or Basic Auth)
Uploading your theme via the BigCommerce control panel’s GUI is compatible with any store token (whether OAuth or Basic-Auth), and with any OAuth token scope, and with all versions of Stencil CLI. However, this option requires that you first use stencil bundle to package your theme into a .zip file. (Prepare your file according to Bundle Only above.)
For the upload steps in the control panel, see the Uploading Custom Themes article in our Knowledge Base.
For error codes that you might encounter when uploading a theme – and corresponding workarounds, see Troubleshooting Theme Uploads.
Command-Line Upload (OAuth Required)
The stencil push command allows you to both bundle your theme and upload it to the store, with a single terminal command. To run stencil push, you must first:
Successfully initialize your theme using an OAuth token that was created with the Themes:modify scope. Install Stencil CLI version 1.12.0 or higher.
To check your current Stencil CLI version, enter
stencil --version or
stencil -V on the command line. If you need to update an earlier version, reinstall Stencil CLI.
Pushing a Theme Upload
To initiate bundling and upload, enter the following on the command line:
Stencil CLI is designed to display the same notifications, prompts, and selection options that you would receive when using the control panel’s GUI. Below are some of the notifications and interactions you might see.
Stencil CLI will display
ok confirmations, or
not ok errors, or
warnings for individual substeps in bundling and uploading your theme. If bundling is successful, you will next see a
Processing progress bar to track the upload.
Upon a successful upload, you will be prompted:
Would you like to apply your theme to your store at <storehash>? (y/N) Any response except
Y will be processed as “No.” You can always apply the theme later through the control panel.
Apply Which Variation?
If you chose to apply the newly uploaded theme, you will be prompted:
Which variation would you like to apply? (Use arrow keys)
Use your arrow keys to move the selection caret/highlight to the variation you want, and then press
Stencil CLI will then confirm which variation is active on the storefront.
Custom themes – which are available for selection – will have a circle to their left. Marketplace themes and the store’s active theme – all of which are protected from deletion – will be flagged
Use your arrow keys to move the selection caret to each theme/version that you want to select. Then press the spacebar to select it. (Filled circles will indicate your selected themes/versions.)
If you are certain of your selections, you can next press
Enter to delete the themes.
Once you press
Enter, the selected themes will be deleted immediately, with no further confirmation.
If you have any doubts – especially about deleting multiple themes/versions – it is safest to delete them through the control panel GUI. This GUI allows you to compare uploaded versions, and to inspect their metadata.
Other Bundling or Upload Errors
