This is a fork of the STAC Browser to make it work with IPLD.
First convert your STAC catalog to IPLD with ipld-stac. Remember the root CID that it outputs.
Now build the STAC Browser:
$ CATALOG_URL=ipld/<the-root-cid> npm run build
This will create a deployable STAC Browser in the dist
directory.
Now put the files created by ipld-stac into dist/ipld
. You can now run an HTTP server inside dist
or just deploy the contents of dist
somewhere.
You can deploy the dist
directory to GitHub pages. This is a hacky, but quick way:
$ cd dist
$ git init .
$ git remote add origin [email protected]:<username>/<repository>.git
$ git checkout --orphan gh-pages
$ git add *
$ git commit -m "Initial commit"
$ git push origin gh-pages
You can find an example at https://vmx.github.io/stac-browser/index.html.
Below is the original README.
This is a Spatio-Temporal Asset Catalog (STAC) browser for static catalogs. It attempts to surface all included data in a user-centric way (an approach which can inform how data is represented in the evolving spec). It is implemented as a single page application (SPA) for ease of development and to limit the overall number of catalog reads necessary when browsing (as catalogs may be nested and do not necessarily contain references to their parents).
- planet.stac.cloud (catalog on GitHub)
- CBERS (catalog tools on GitHub)
- Google Earth Engine
- sat-api.stac.cloud (sat-api on GitHub)
For a longer list of examples, checkout out stac.cloud.
By default, stac-browser will browse the testbed Planet
catalog
(GitHub). To browse your own, set
CATALOG_URL
when building.
npm install
CATALOG_URL=http://path/to/catalog.json npm start -- --open
STAC Browser defaults to using HTML5 History
Mode, which can
cause problems on certain web hosts. To use hash mode, set
HISTORY_MODE=hash
when running or building. This will be compatible with
S3, stock Apache, etc.
CATALOG_URL=http://path/to/catalog.json npm run build
STAC Browser includes the ability to prerender catalog pages to HTML using Puppeteer to control a headless Chromium instance. This facilitates search engine indexing, as metadata and content will be present in the HTML prior to loading external catalogs.
To prerender, run:
bin/prerender.js -p <public URL> <catalog URL>
dist/
will contain all assets necessary to host the browser.
After publishing (see below), the generated sitemap can be submitted for crawling by Google:
curl http://www.google.com/ping?sitemap=https://planet.stac.cloud/sitemap.txt
After building or prerendering, dist/
will contain all assets necessary to
host the browser. These can be manually copied to your web host of choice.
Alternately, you can publish to Netlify for free.
First, create a new site:
node_modules/.bin/netlify init
The generated site id will be used as NETLIFY_SITE_ID
in your environment.
To deploy without prerendering:
CATALOG_URL=... NETLIFY_SITE_ID=... npm run deploy
To deploy a prerendered version you'll also need the target URL:
CATALOG_URL=... NETLIFY_SITE_ID=... STAC_URL=... npm run deploy-prerendered
To facilitate prerendering, STAC Browser includes functionality for crawling
catalogs in bin/crawl.js
.
As-is, this will just output the type and URL for all entries in the catalog.
In real-world use, you'll probably want to use it as an example and write
custom JavaScript to process each entry (similar to how bin/prerender.js
uses it).
STAC Browser uses Vue.
Catalogs and collections are rendered using the
Catalog
component in
src/components/
. Items are rendered using the
Item
component. Common functionality across both
components exists in src/components/common.js
.
Mappings between property keys (e.g. eo:platform
) are defined in
src/lib/stac/dictionary.json
.
