Usage

Requirements

Running the Origami Set module requires Node.js 10.x and npm. You can install with:

npm install @financial-times/origami-image-set-tools

Command-Line Interface

This module exposes an oist command which can be used to manage image sets from the command line:

Usage: oist [options] [command]


Commands:

  build-manifest [options]   build an image set manifest file and save to "imageset.json"
  publish-s3 [options]       publish the image set to an S3 bucket for use by the Image Service
  purge [options]            request each image in the image set to be purged from the Origami Image Service
  verify [options]           verify that images in the source directory are valid and have no issues
  *                          unrecognised commands will output this help page

Options:

  -h, --help     output usage information
  -V, --version  output the version number

Build Manifest

The oist build-manifest command creates a JSON manifest file detailing all of the images in the set. An imageset.json file will be created in the current working directory. The output JSON format is documented here.

Usage: oist build-manifest [options]

build an image set manifest file and save to "imageset.json"

Options:

  -h, --help                    output usage information
  -s, --source-directory <dir>  The directory to look for source images in
  -c, --scheme <scheme>         The custom scheme this image set should be published under
  -l, --legacy                  Whether to output the legacy manifest format

Options can also be set as environment variables:

--source-directory can be set with IMAGESET_SOURCE_DIRECTORY
--scheme can be set with IMAGESET_SCHEME

Publish to S3

Usage: publish-s3 [options]

publish the image set to an S3 bucket for use by the Image Service

Options:

  -h, --help                      output usage information
  -a, --aws-access-key <key>      The AWS access key to use in authentication
  -S, --aws-secret-key <key>      The AWS access key secret to use in authentication
  -b, --bucket <bucket>           The name of the S3 bucket to publish to
  -s, --source-directory <dir>    The directory to look for source images in
  -c, --scheme <scheme>           The custom scheme to publish this image set under
  -v, --scheme-version <version>  The version to publish this image set under

Options can also be set as environment variables:

--aws-access-key can be set with AWS_ACCESS_KEY
--aws-secret-key can be set with AWS_SECRET_KEY
--bucket can be set with AWS_BUCKET
--source-directory can be set with IMAGESET_SOURCE_DIRECTORY
--scheme can be set with IMAGESET_SCHEME
--scheme-version can be set with IMAGESET_VERSION

Purging an image set

The oist purge command will trigger a purge request for all images in the set.

Usage: purge [options]

request each image in the image set to be purged from the Origami Image Service


Options:

  -s, --source-directory <dir>    The directory to look for source images in
  -c, --scheme <scheme>           The custom scheme to purge this image set under
  -v, --scheme-version <version>  The version to publish this image set under
  --image-service-api-key <key>   The API key used to communicate with the Origami Image Service
  -h, --help                      output usage information

Verify

The oist verify command checks all of the images in the set to ensure that they're valid.

Usage: oist verify [options]

  verify that images in the source directory are valid and have no issues

  Options:

    -h, --help                    output usage information
    -s, --source-directory <dir>  The directory to look for source images in

Options can also be set as environment variables:

--source-directory can be set with IMAGESET_SOURCE_DIRECTORY

API Documentation

This library makes use of promises, and provides a wrapper around part of S3 – familiarity is assumed in the rest of the API documentation. You'll also need to require the module with:

const OrigamiImageSetTools = require('@financial-times/origami-image-set-tools');

`new OrigamiImageSetTools( [options] )`

This function returns a new Origami Image Set Tools instance. You can configure the created tool set with an options object if you need to override any defaults.

const toolSet = new OrigamiImageSetTools({
    example: 'value'
});

`toolSet.buildImageSetManifest()`

This function returns a promise which resolves with a built image set manifest. This uses the baseDirectory and sourceDirectory options to determine where to find images.

The image manifest has the following format:

{
    // The directory the images were sourced from
    sourceDirectory: 'src',

    // The custom scheme the images should be stored
    // under in the Image Service
    scheme: 'ftexample',

    // A list of the found images
    images: [

        // The name, extension, and full path of each image
        {
            name: 'myimage',
            extension: 'svg',
            path: 'src/myimage.svg'
        }

    ]
}

`toolSet.buildLegacyImageSetManifest()`

This function returns a promise which resolves with a built legacy image set manifest. This is a stripped down version of the buildImageSetManifest method.

The legacy image manifest has the following format:

{
    // A list of the found images
    images: [

        // The name of each image
        {
            name: 'myimage'
        }

    ]
}

`toolSet.buildImageSetManifestFile()`

This function returns a promise which builds image set information (using buildImageSetManifest) then saves it to a file as JSON.

This uses the baseDirectory and sourceDirectory options to determine where to find images and where to save the file. The file will be created at <baseDirectory>/imageset.json.

`toolSet.buildLegacyImageSetManifestFile()`

This function returns a promise which builds legacy image set information (using buildLegacyImageSetManifest) then saves it to a file as JSON.

This uses the baseDirectory and sourceDirectory options to determine where to find images and where to save the file. The file will be created at <baseDirectory>/imageList.json.

`toolSet.publishToS3( bucket )`

This function returns a promise which builds image set information (using buildImageSetManifest) then publishes each image to the given S3 bucket.

This uses the awsAccessKey and awsSecretKey options to gain access to the bucket – these should grant write access.

The scheme and version options are also used to calculate where the images will be uploaded to. If scheme is set to myscheme and version is set to v4.5.6, then:

[LOCAL]/src/myimage.png === [S3]/myscheme/v4/myimage

`toolSet.verifyImages()`

This function returns a promise which verifies that each image in the set is valid.

This uses the baseDirectory and sourceDirectory options to determine where to find images. If any verification fails, this method will reject with an error that has a verificationErrors property.

Options

The Origami Image Set Tools module can be configured with a variety of options, passed in as an object to the OrigamiImageSetTools function. The available options are as follows:

awsAccessKey: The AWS Access Key ID to use when publishing images to S3. Required when using the publishToS3 method. Defaults to null
awsSecretKey: The AWS Secret Key to use when publishing images to S3. Required when using the publishToS3 method. Defaults to null
baseDirectory: The base directory of the image set, where the manifest files sit. Image set JSON files will be created here. Defaults to the current working directory
log: A console object used to output non-request logs. Defaults to the global console object
scheme: The custom scheme to use when publishing to S3. This will dictate the folder structure of the S3 bucket. Defaults to "noscheme"
sourceDirectory: The directory relative to baseDirectory where the actual image files are located. Defaults to "src"
version: The version to use when publishing to S3. The major part of this version number will dictate the folder structure of the S3 bucket. Defaults to "v0.0.0"

Contributing

This module has a full suite of unit and integration tests, and is verified with ESLint. You can use the following commands to check your code before opening a pull request.

npm t

You'll need to provide TEST_AWS_ACCESS_KEY and TEST_AWS_SECRET_KEY environment variables in order to run integration tests. You may also provide a TEST_AWS_BUCKET variable to override the test bucket name.

You can find the AWS keys in the Origami shared LastPass folder under "Imageset S3 Bucket credentials" – be sure to use the development/QA ones!

Publishing

New versions of the module are published automatically by CI when a new tag is created matching the pattern /v.*/.
