@astrojs/underscore-redirects
minor

Updates the input requirements of createRedirectsFromAstroRoutes:

• routeToDynamicTargetMap keys are IntegrationResolvedRoute instead of IntegrationRouteData (obtained from the astro:routes:resolved hook)
• There's a new assets property, that can be obtained from the astro:build:done hook

function myIntegration() {
    let routes
    let buildOutput
    let config

    return {
        name: "my-integration",
        hooks: {
            "astro:routes:resolved": (params) => {
                routes = params.routes
            },
            "astro:config:done": (params) => {
                buildOutput = params.buildOutput
                config = params.config
            },
            "astro:build:done": (params) => {
                const redirects = createRedirectsFromAstroRoutes({
                    config,
                    buildOutput,
                    routeToDynamicTargetMap: new Map(
                        routes.map(route => [route, ''])
                    ),
                    dir: params.dir,
                    assets: params.assets
                })
            }
        }
    }
}
