aws-s3-facia-tool

API on top of facia tool storage

Dependencies

This package has a peer dependency on aws-sdk version 2.x.

Installation

npm install aws-s3-facia-tool --save

Usage

const facia = require('aws-s3-facia-tool');
const client = new facia.Client({
    'bucket': 'bucket-used-by-fronts-tool',
    'env': 'CODE',
    'configKey': 'where/config.json/lives',
    'configHistoryPrefix': 'path/containing/config/history',
    'collectionHistoryPrefix': 'path/containing/collections/history',
    'collectionsPrefix': 'path/containing/collection.json',
    'pressedPrefix': 'path/containing/pressed.json',
    'maxParallelRequests': 6,
    'maxDaysHistory': 7
});

Config

const facia = require('aws-s3-facia-tool');
const client = new facia.Client({});
facia.Config(client).fetch()
.then(config => {
    // use the config here
})

• Config.fetch() - Fetch the config JSON from the bucket, returns a Config class
• Config.head() - Performs a head action, the resulting promise is resolved with the config metadata (e.g. ETag, LastModified)
• Config.get() - Returns the Config class using in memory cache, it reads from the bucket only when the cache is empty.
• Config.json() - Returns the config JSON instead of the utility class. It uses the cache
• Config.fetchAt(key) - Returns a Config class reading from key instead of the internal configuration

Config class

Instances of Config class have the following methods

• hasFront(front) - Boolean, whether a front exists
• hasCollection(id) - Boolean, whether a collection with id exists
• listFrontsIds(priority) - List of all front id. Optionally filter by priority
• listCollectionsIds() - List of all collection id
• front(path) - Return a Front class for the given path
• collection - Return a Collection class for the given id
• fronts.find(query) - Return a list of Front classes for all paths that match the query
• collections.find(query) - Return a list of Collection classes for all paths that match the query

Collection

const facia = require('aws-s3-facia-tool');
const client = new facia.Client({});
facia.Collection(client).fetch()
.then(collection => {
    // use the collection here
})

• fetch (id, config) - Fetch a collection id. config is optional if you're just interested in the collection content, otherwise pass a config object
• fetchAt (id, key, config) - Fetch a collection with id at a specified key
• list() - List all collections in the bucket (including the ones that have been removed from fronts)

Collection class

Instances of Front class have the following methods

• forEachArticle(action) - Perform an action for each item in the collection. action receives (stage, article) where stage is live / draft / treats
• setContent(json) - Set the content of the collection
• setKey(key) - Set the key storing the collection content
• toJSON() - Return the collection as JSON. The result object contains
  • config: the collection config
  • collection: the collection content
• trails(stage) - Return the list of trail in stage (live / draft / treats)
• lastUpdated() - Return the last updated date
• isBackfilled() - Whether the collection has a backfill
• hasMetadata(type) - Whether the collection has metadata of type (e.g. collection tags)
• layout() - Return the collection layout
• visibleStories(scope) - Number of visible stories (above show more) on desktop and mobile

Front

const facia = require('aws-s3-facia-tool');
const client = new facia.Client({});
facia.Front(client).fetch()
.then(front => {
    // use the front here
})

• fetch (path, config) - Fetch a front with path. config is optional, the tool will get it from S3 if not specified

Front class

Instances of Front class have the following methods

• toJSON() - Return the front a JSON. The result object contains
  • config: the front configuration
  • collections: the collections configuration
  • collectionsFull: the collections content
• setCollection(id, collection) - Set the content a collection
• collection(id) - Return a Collection class for the collection with id
• lastUpdated() - Return the last updated date
• priority() - Return the explicit priority
• listCollectionsIds() - List all collection id

Press

const facia = require('aws-s3-facia-tool');
const client = new facia.Client({});
facia.Press(client).getLastModified('front-path', 'live')
.then(lastModified => {
    // date
})

• getLastModified(path, location) - Get the last modified date of a front in either live or draft
