ObjectStorage OVH
Simple library to use OVH Public Cloud Object Storage.
Create and manage containers (public, private or static), add and manage objects in OVH Public Cloud (OpenStack).
Based on developer.openstack.org official documentation.
A complete JSDoc is
available here
.
some breakpoints, if you want to use this version, it's recommended to
refactoring all your projects.
To use the previous version (V1), go
on #v1.0.x branch.
🎉 Features
- Get account details and manage metas (create, update, has, get or delete),
- Create, list, get details or delete containers,
- Check if object exist in a container,
- Define metas (create, update, has, get or delete) for container,
- List files on a container,
- Import object on container
- Download or get content of object,
- Get temporary download link object,
- Delete all object in containers,
- Program automatic delete of an object on datetime or after seconds,
- Manage metas on objects (create, update, has, get or delete).
📍 Install via npm
npm install node-ovh-objectstorage --save
🧮 Examples :
Authentification
Requesting a token to make operations on container.
var OVHStorage = require('node-ovh-objectstorage');
var config = {
username: '******',
password: '******',
authURL: 'https://auth.cloud.ovh.net/v3/auth',
tenantId: '******',
region: 'SBG',
// key is optional
key: "Temporary key (optional), for generate temporary download link",
// options is optional
options: {
slugify : true, // true, by default
check_exists: true, // true, by default
}
};
(async () => {
try {
let storage = new OVHStorage(config);
await storage.connection();
} catch (e) {
// throw e
}
