An independent Linux desktop alternative to Swagger UI for browsing grouped REST endpoints, resolving nested $ref component pointers, generating request code snippets, and publishing self-contained HTML documentation without a browser. Key Features: * Endpoints & Paths Browser: Parses OpenAPI 3.0 and Swagger 2.0 JSON and YAML files into tag-grouped endpoint trees with colored GET/POST/PUT/DELETE/PATCH method badges, path and query parameters, request bodies, and response codes. * $ref Schema Explorer & Sample Payload Synthesizer: Recursively resolves #/components/schemas and #/definitions $ref pointers (including allOf, nested arrays, and cycle protection) to synthesize typed JSON example payloads along with ready-to-run curl and Python snippets. * Static HTML Docs & Inventory Exporter: Exports standalone dark or light HTML API reference pages and structured CSV endpoint inventory spreadsheets. Disclaimer: OpenAPI Spec Viewer is an independent open-source project by TC Studio and is not affiliated with, endorsed by, or sponsored by Swagger UI. ### Package name * openapi-spec-viewer --- ### License * MIT --- ### Last updated * Yesterday - latest/stable --- ##### Report a Snap Store violation * [Report this Snap](https://snapcraft.io/install/openapi-spec-viewer/rhel#report-snap-modal) --- [See more information about openapi-spec-viewer ›](https://snapcraft.io/openapi-spec-viewer) ## Enable snaps on Red Hat Enterprise Linux and install OpenAPI Spec Viewer Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully. Snaps are discoverable and installable from the [Snap Store](https://snapcraft.io/store), an app store with an audience of millions. ### Enable snapd Snap is available for [Red Hat Enterprise Linux (RHEL) 8](https://www.redhat.com/en/enterprise-linux-8) and RHEL 7, from the 7.6 release onward. The packages for RHEL 7, RHEL 8, and RHEL 9 are in each distribution’s respective [Extra Packages for Enterprise Linux](https://fedoraproject.org/wiki/EPEL) (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 7, RHEL 8 and RHEL 9, which is why they’re listed separately below. The EPEL repository can be added to **RHEL 9** with the following command: ``` sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm sudo dnf upgrade ``` The EPEL repository can be added to **RHEL 8** with the following command: ``` sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm sudo dnf upgrade ``` The EPEL repository can be added to **RHEL 7** with the following command: ``` sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm ``` Adding the *optional* and *extras* repositories is also recommended: ``` sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms" sudo yum update ``` Snap can now be installed as follows: ``` sudo yum install snapd ``` Once installed, the *systemd* unit that manages the main snap communication socket needs to be enabled: ``` sudo systemctl enable --now snapd.socket ``` To enable *classic* snap support, enter the following to create a symbolic link between `/var/lib/snapd/snap` and `/snap`: ``` sudo ln -s /var/lib/snapd/snap /snap ``` Either log out and back in again or restart your system to ensure snap’s paths are updated correctly. ### Install OpenAPI Spec Viewer To install OpenAPI Spec Viewer, simply use the following command: ``` sudo snap install openapi-spec-viewer ``` ### Other popular snaps… [See more...](https://snapcraft.io/search?categories=featured) [See more in Featured](https://snapcraft.io/search?categories=featured) ### More things to do… #### [Get the snap store](https://snapcraft.io/snap-store) Browse and find snaps from the convenience of your desktop using the snap store snap. #### [Learn more about snaps](https://snapcraft.io/docs) Interested to find out more about snaps?
