warehouse-models

warehouse-models

Data models for Warehouse.ai. Built on top of dynamodb and dynastar.

Install

npm install --save warehouse-models

Usage

All of the objects returned from this module have the same api as dynastar with the schemas as mentioned later.

const dynamo = require('dynamodb-x')
const models = require('warehouse-models')(dynamo);

...
// from passing dynamodb.define to the constructor of dynastar we get...
const Build = models.Build;
const Version = models.Version;
...

Build.findFirst({ ... }, function (err, data) { .... });

*** Note that with the new dynamo release of warehouse-models (V.6.0.0), you will to need to provide a value for locale as part of the argument to findOne.

Build.findOne({ name: 'email', env: 'prod'}, function (err, data) { .... }); // pre 6.0.0
Build.findOne({ name: 'email', env: 'prod', locale: 'en-US' }, function (err, data) { .... }); // post 6.0.0

API

All schemas for the API documentation are written using dynamodb's notation.

The following sections contain the column/attribute mappings for each table.

Legend:

(pk) - partition-key (sk) - sort/range key

Build Head (build_head)

Represent the head build version of an entire package. On an npm install, the env will have to be passed in.

Column	Type	Summary
key (pk)	string	${name}!${env}!${version}
name	string	What package has been build
env	string	What environment is this build made for (dev, test, etc.)

Dependent (dependent)

A dependency graph where every packaged publish can ensure that any package that depends on it can be updated. This should constantly be updated on every publish.

Column	Type	Summary
name (pk)	string	Name of a package
dependents	stringSet	Name of packages are dependent on me

Dependent Of (dependent_of)

An inverse of dependent in order for a dependent package to see what its parent is.

Column	Type	Summary
pkg (pk)	string	Name of a package
dependentOf	string	Name of the parent package

Release Line (release_line)

Represent all the necessary information for a given package/version to know what needs to be deployed, considering all its dependents as well. (When combined with Release Line Dependents)

Column	Type	Summary
key (pk)	string	${pkg}!${version}
pkg	string	Name of a package
version	string	The current version number or latest
previousVersion	string	The previous version number

Release Line Dependents (release_line_dep)

Represent all the necessary information for a given package/version to know what needs to be deployed, considering all its dependents as well. (When combined with Release Line)

Column	Type	Summary
key (pk)	string	${pkg}!${version}
pkg	string	Name of a package
version	string	The current version number
previousVersion	string	The previous version number
dependent (sk)	string	The dependent package
dependentVersion	string	The dependent package version

Release Line Head (release_line_head)

Represents the head release-line for a given package.

Column	Type	Summary
pkg (pk)	string	Name of a package
previousVersion	string	The previous version number
version	string	The current version number

Version (version)

Records of every npm publish of a package to the registry. Mostly needed for npm install from the builder, as it will npm install a specific tag. That tag will be tied to a specific version (look at the package table). A lookup will occur against the version table afterwards to send down the package.json.

Column	Type	Summary
name (pk)	string	Name of a package
version (sk)	string	Version of a package
value	string	Full json sent of an npm publish

Package (package)

Represent an entire published packaged (package.json) to the registry. Because the number of properties in package.json could be infinite, only relevant columns are described.

Examples of package.json

• Warehouse.ai
• Express
• npm

Column	Type	Summary
name (pk)	string	Name of a package
version	string	Version of a package
description	string	Package description
main	string	Export file of a package
gitHead	string	HEAD git sha of package
extended	map	object of any other properties we have
keywords	stringSet	package.json keywords array
bundledDependencies	stringSet	any bundled dependencies of a package
distTags	map	Mapping of tag to version e.g. { "production": "1.1.0" }

repository	map	Repo config of package.json
dependencies	map	Deps of package
