- i am not super happy about `const imageLib = require('../lib/image')`
- i don't really like the name `imageLib`
- but i had no better idea 😃
- if we use the same name in the whole project, it's very easy to rename the folder or the variable
no issue
- Consistent naming for postLookup
- makes it easier to search and inspect the various usages
- Cleanup unneeded code
- Make res.render calls more consistent
- add some consistency to the calls to res.render
- Remove ancient reference to dataProvider
- Let's call it models everywhere now...
- Use consistent formatting across the API
- we're no longer using alignment in vars
- Misc other consistency changes in API
- always refer to local utils as apiUtils
- logical grouping of requires - dependencies, utils, "lib common" etc
- use xAPI to refer to API endpoints, e.g. mailAPI, settingsAPI for clarity
refs #8868
- Removed image-size in blog logo fn for meta data and made it synchronous
- Renamed `image-size-from-url.js` to `image-size.js` (incl. the test)
- Added second fn `getImageSizeFromFilePath` that reads from local file storage
- Added guard in `getImageSizeFromUrl` that checks if the image should be on local file storage and uses the new fn then instead
- Added a fn `fetchDimensionsFromBuffer` that takes the file buffer and returns an `imageObject` with dimensions.
- Added a new utils.js in `adapters/storage` for getting the file storage path
closes#8334
- adds title, image and description to structured data to be rendered as open graph and twitter data.
- if meta title and description for a post exists already, the custom structured data will overwrite those for `og:` and `twitter:` data. `JSON-LD` (Schema.org`) is not affected and will stay the same.
- adds tests
- adds new og and twitter fields to schema incl. migration
refs #8221, closes#7688, refs #7558🙇 Improve meta data publisher logo behaviour
This is a follow-up PR for #8285.
Reasons: The code changes of #8285 caused error messages when falling back to the default `favicon.ico`, as the `image-size` tool doesn't support `ico` files.
This PR takes the logic to decide which logo needs to be listed in our schema into a new fn `blog_logo.js`. There we have now three decisions:
1. If we have a publication **logo**, we'll take that one
2. If we have no publication logo, but an **icon** we'll use this one.
3. If we have none of the above things, we fall back to our default `favicon.ico`
Additional, we're hard coding image dimensions for whenever the logo is an `.ico` file and built and extra decision to not call `image-size` when the dimension are already given.
I will create another follow-up PR, which checks the extension type for the file and offers it as a util.
🛠 Blog icon util
refs #7688
Serve functionality around the blog icon in its own util:
- getIconDimensions -> async function that takes the filepath of on ico file and returns its dimensions
- isIcoImageType -> returns true if file has `.ico` extension
- getIconType -> returns icon-type (`x-icon` or `png`)
- getIconUrl -> returns the absolut or relativ URL for the favicon: `[subdirectory or not]favicon.[ico or png]`
📖 Get .ico sizes for meta data & logo improvement
refs #7558
refs #8221
Use the new `blogIconUtil` in meta data to fetch the dimensions of `.ico` files.
Improvements for `publisher.logo`: We're now returning a hard-coded 'faked' image dimensions value to render an `imageObject` and prevent error our schema (Google structured data). As soon as an image (`.ico` or non-`.ico`) is too large, but - in case of non-`.ico` - a square format, be set the image-dimensions to 60px width and height. This reduces the chances of getting constantly error messages from Googles' webmaster tools.
- add getIconPath util
closes#6588, #7095
* `ImageObject` with image dimensions (#7152, #7151, #7153)
- Returns meta data as promise
- returns a new Promise from meta data
- uses `Promise.props()` to resolve `getClient()` and `getMetaData()`
- Adds 'image-size' util
The util returns an object like this
```
{
height: 50,
url: 'http://myblog.com/images/cat.jpg',
width: 50
};
```
if the dimensions can be fetched and rejects with error, if not.
In case we get a locally stored image or a not complete url (like `//www.gravatar.com/andsoon`), we add the protocol to the incomplete one and use `urlFor()` to get the absolute URL. If the request fails or `image-size` is not able to read the file, we reject with error.
- adds 'image-size' module to dependencies
- adds `getImageSizeFromUrl` function that returns image dimensions
- In preparation of AMP support and to improve our schema.org JSON-LD and structured data, I made the following changes:
- Changes the following properties to be `Objects`, which have a `url` property by default and a `dimensions` property, if `width` and `height` are available:
- `metaData.coverImage`
- `metaData.authorImage`
- `metaData.blog.logo`
- Checks cache by calling `getCachedImageSizeFromUrl`. If image dimensions were fetched already, returns them from cache instead of fetching them again.
- If we have image dimensions on hand, the output in our JSON-LD changes from normal urls to be full `ImageObjects`. Applies to all images and logos.
- Special case for `publisher.logo` as it has size restrictions: if the image doesn't fulfil the restrictions (<=600 width and <=60 height), we simply output the url instead, so like before.
- Adds new property for schema.org JSON-LD: `mainEntityOfPage` as an Object.
- Adds additional Open Graph data (if we have the image size): `og:image:width` and `og:image:height`
- Adds/updates tests
* AMP router and controller (#7171, #7157)
Implements AMP in `/apps/`:
- renders `amp.hbs` if route is `/:slug/amp/`
- updates `setResponseContext` to set context to `['amp', 'post']` for a amp post and `['amp', 'page']` for a page, but will not render amp template for a page
- updates `context_spec`
- registers 'amp' as new internal app
- adds the `amp.hbs` template to `core/server/apps/amp` which will be the default template for AMP posts.
- adds `isAmpURL` to `post-lookup`
* 🎨 Use `context` in meta as array (#7205)
Instead of reading the first value of the context array, we're checking if it includes certain context values.
This is a preparation change for AMP, where the context will be delivered as `['amp', 'post']`.
* ✨ AMP helpers (#7174, #7216, #7215, #7223)
- Adds AMP helpers `{{amp_content}}`, `{{amp_component}}` and `{{amp_ghost_head}}` to support AMP:
- `{{amp_content}}`:
- Adds `Amperize` as dependency
- AMP app uses new helper `{{amp_content}}` to render AMP HTML
- `Amperize` transforms regular HTML into AMP HTML
- Adds test for `{{amp_content}}` helper
- Adds 'Sanitize-HTML` as dependendy
- After the HTML get 'amperized' we still might have some HTML tags, which are prohibited in AMP HTML, so we use `sanitize-html` to remove those. With every update, `Amperize` gets and it is able to transform more HTML tags, they valid AMP HTML tags (e. g. `video` and `amp-video`) and will therefore not be removed.
- `{{amp_ghost_head}}`:
- registers `{{amp_ghost_head}}` helper, but uses `{{ghost_head}}` code
- uses `{{amp_ghost_head}}` in `amp.hbs` instead of `{{ghost_head}}`
- `{{ghost_head}}`:
- Render `amphtml` link in metadata for post, which links to the amp post (`getAmpUrl`)
- Updates all test in metadata to support `amp` context
- Changes context conditionals to work with full array instead of first array value
- Adds conditionals, so no additional javascript gets rendered in `{{ghost_head}}`
- Removes trailing `/amp/` in URLs, so only `amphtml` link on regular post renders it
- Adds a conditional, so no code injection will be included, for an `amp` context.
- `{{amp_components}}`:
- AMP app uses new helper `{{amp_components}}` to render necessary script tags for AMP extended components as `amp-iframe`, `amp-anime` and `amp-form`
- Adds test for `{{amp_components}}`
