[{"name":"DataSource","comment":" StaticHttp requests are an alternative to doing Elm HTTP requests the traditional way using the `elm/http` package.\n\nThe key differences are:\n\n - `StaticHttp.Request`s are performed once at build time (`Http.Request`s are performed at runtime, at whenever point you perform them)\n - `StaticHttp.Request`s strip out unused JSON data from the data your decoder doesn't touch to minimize the JSON payload\n - `StaticHttp.Request`s can use [`Pages.Secrets`](Pages.Secrets) to securely use credentials from your environment variables which are completely masked in the production assets.\n - `StaticHttp.Request`s have a built-in `StaticHttp.andThen` that allows you to perform follow-up requests without using tasks\n\n\n## Scenarios where StaticHttp is a good fit\n\nIf you need data that is refreshed often you may want to do a traditional HTTP request with the `elm/http` package.\nThe kinds of situations that are served well by static HTTP are with data that updates moderately frequently or infrequently (or never).\nA common pattern is to trigger a new build when data changes. Many JAMstack services\nallow you to send a WebHook to your host (for example, Netlify is a good static file host that supports triggering builds with webhooks). So\nyou may want to have your site rebuild everytime your calendar feed has an event added, or whenever a page or article is added\nor updated on a CMS service like Contentful.\n\nIn scenarios like this, you can serve data that is just as up-to-date as it would be using `elm/http`, but you get the performance\ngains of using `StaticHttp.Request`s as well as the simplicity and robustness that comes with it. Read more about these benefits\nin [this article introducing StaticHttp requests and some concepts around it](https://elm-pages.com/blog/static-http).\n\n\n## Scenarios where StaticHttp is not a good fit\n\n - Data that is specific to the logged-in user\n - Data that needs to be the very latest and changes often (for example, sports scores)\n\n@docs DataSource\n\n@docs map, succeed, fail\n\n@docs fromResult\n\n\n## Building a StaticHttp Request Body\n\nThe way you build a body is analogous to the `elm/http` package. Currently, only `emptyBody` and\n`stringBody` are supported. If you have a use case that calls for a different body type, please open a Github issue\nand describe your use case!\n\n@docs Body, emptyBody, stringBody, jsonBody\n\n\n## Chaining Requests\n\n@docs andThen, resolve, combine\n\n@docs map2, map3, map4, map5, map6, map7, map8, map9\n\n","unions":[],"aliases":[{"name":"Body","comment":" A body for a StaticHttp request.\n","args":[],"type":"Pages.Internal.StaticHttpBody.Body"},{"name":"DataSource","comment":" A DataSource represents data that will be gathered at build time.
