Initial setup

Install dependencies

Install nvm on your workstation if you have not already:

Then run:

$ nvm use lts/fermium
$ npm install

Enable website hosting on the AWS S3 bucket:

The following command should be run only during the initial setup of the S3 bucket. Do not run this command again or it will wipe out the S3 website redirection rules.

aws s3 website s3://northernclimatereports.org/ --index-document index.html --error-document index.html

Add website redirection rules to S3 bucket

Website redirection rules need to be added to the S3 bucket for data to hydrate properly when a report is referenced directly by its URL (permalink).

From the AWS web interface for the S3 bucket, go to:

Properties → Static website hosting → Edit

In the "Redirection rules" text area, add the following:

[
    {
        "Condition": {
            "HttpErrorCodeReturnedEquals": "404"
        },
        "Redirect": {
            "HostName": "northernclimatereports.org",
            "Protocol": "https",
            "ReplaceKeyPrefixWith": "#!/"
        }
    },
    {
        "Condition": {
            "HttpErrorCodeReturnedEquals": "403"
        },
        "Redirect": {
            "HostName": "northernclimatereports.org",
            "Protocol": "https",
            "ReplaceKeyPrefixWith": "#!/"
        }
    }
]

Code in components/App.vue catches and routes these redirects into fully hydrated report pages.

Development

Set environment variables if necessary

The following environment variables can be set to change the API and map service endpoints:

Environment variable	Default
GEOSERVER_URL	https://gs.mapventure.org/geoserver/wms
RASDAMAN_URL	https://zeus.snap.uaf.edu/rasdaman/ows
SNAP_API_URL	https://earthmaps.io

Run locally in development mode

Serve with hot reload at http://localhost:3000:

$ npm run dev

Deployment

Set environment variables if necessary, then run:

$ npm run generate
$ aws s3 cp dist s3://northernclimatereports.org/ --acl public-read --recursive

You will also need to invalidate the CloudFront cache for northernclimatereports.org. Find the distribution for northernclimatereports.org in the AWS CloudFront web interface, then go to:

Invalidations → Create invalidation

Use the following CLI command:

aws cloudfront create-invalidation --distribution_id EZEXS6RHS812M --paths "/*"
