| 1 | //! GitHub: signing in with a GitHub account, and bringing repositories |
| 2 | //! across through g1t's GitHub App. Mirrors `packages/contracts/src/github.ts`. |
| 3 | //! |
| 4 | //! One GitHub App does both. Its user authorization (OAuth web flow, with |
| 5 | //! PKCE) signs people in and lets g1t list what they installed it on; its |
| 6 | //! installations give g1t access to the repositories they chose. The app |
| 7 | //! is optional: with none configured every method here says so, and the |
| 8 | //! site shows no GitHub buttons. |
| 9 | //! |
| 10 | //! The identity service (`POST /rpc/<method>`) keeps linked accounts and |
| 11 | //! their user tokens: |
| 12 | //! |
| 13 | //! - `github_enabled` (no arguments) returns `bool`. |
| 14 | //! - `github_start` takes `GithubStartArgs`, returns `Outcome<GithubStart>`. |
| 15 | //! - `github_finish` takes `GithubFinishArgs`, returns `Outcome<GithubFinished>`. |
| 16 | //! - `github_pending` takes `GithubPendingArgs`, returns `Outcome<GithubPending>`. |
| 17 | //! - `github_sign_up` takes `GithubSignUpArgs`, returns `Outcome<SignedIn>`. |
| 18 | //! - `github_claim` takes `GithubClaimArgs`, returns `Outcome<GithubAccount>`. |
| 19 | //! - `github_account` takes `UserArgs`, returns `GithubAccountView`. |
| 20 | //! - `github_unlink` takes `UserArgs`, returns `Outcome<bool>`. |
| 21 | //! - `github_user_token` takes `GithubUserTokenArgs`, returns `Outcome<String>`. |
| 22 | //! - `github_revoked` takes `GithubRevokedArgs`, returns `u32`. |
| 23 | //! - `github_usernames` takes `GithubUsernamesArgs`, returns a map. |
| 24 | //! |
| 25 | //! The integrations service keeps installations and linked repositories, |
| 26 | //! and receives the app's webhook at `https://api.g1t.sh/hooks/github`: |
| 27 | //! |
| 28 | //! - `github_status` takes `GithubStatusArgs`, returns `Outcome<GithubAppStatus>`. |
| 29 | //! - `github_add_installation` takes `GithubInstallationArgs`, returns |
| 30 | //! `Outcome<GithubInstallation>`. |
| 31 | //! - `github_remove_installation` takes `GithubInstallationArgs`, returns |
| 32 | //! `Outcome<bool>`. |
| 33 | //! - `github_visible_installations` takes `GithubVisibleArgs`, returns |
| 34 | //! `Outcome<Vec<GithubVisibleInstallation>>`. |
| 35 | //! - `github_repositories` takes `GithubRepositoriesArgs`, returns |
| 36 | //! `Outcome<GithubRepositories>`. |
| 37 | //! - `github_import` takes `GithubImportArgs`, returns `Outcome<GithubRepoLink>`. |
| 38 | //! - `github_link` takes `GithubLinkArgs`, returns `Option<GithubRepoLink>`. |
| 39 | //! - `github_unlink_repo` takes `GithubUnlinkRepoArgs`, returns `Outcome<bool>`. |
| 40 | //! - `github_sync` takes `GithubUnlinkRepoArgs`, returns `Outcome<GithubRepoLink>`. |
| 41 | //! - `github_receive` takes `GithubReceiveArgs`, returns `integrations::Received`. |
