# Barge
|
||||
|
||||
The Barge component of Ocean Protocol is a powerful tool designed to simplify the development process by providing Docker Compose files for running the full Ocean Protocol stack locally. It allows developers to easily set up and configure the various services required by Ocean Protocol for local testing and development purposes.
|
||||
|
||||
By using the Barge component, developers can quickly spin up an environment that includes default versions of Aquarius, Provider, Subgraph, and Compute-to-Data. Additionally, it deploys all the smart contracts from the ocean-contracts repository, ensuring a complete and functional local setup. Barge component also starts additional services like Ganache, which is a local blockchain simulator used for smart contract development, and Elasticsearch, a powerful search and analytics engine required by Aquarius for efficient indexing and querying of data sets. Full list of components and exposed ports can be found here: [https://github.com/oceanprotocol/barge#component-versions-and-exposed-ports](https://github.com/oceanprotocol/barge#component-versions-and-exposed-ports)
|
||||
|
||||
To explore all the available options and gain a deeper understanding of how to utilize the Barge component, you can visit the official GitHub repository of Ocean Protocol at the following link: [https://github.com/oceanprotocol/barge#all-options](https://github.com/oceanprotocol/barge#all-options).
|
||||
|
||||
By utilizing the Barge component, developers gain the freedom to conduct experiments, customize, and fine-tune their local development environment, and offers the flexibility to override the Docker image tag associated with specific components. By simply setting the appropriate environment variable before executing the start\_ocean.sh command, developers can customize the versions of various components according to their requirements. For instance, developers can modify the: AQUARIUS\_VERSION, PROVIDER\_VERSION, CONTRACTS\_VERSION, RBAC\_VERSION, and ELASTICSEARCH\_VERSION environment variables to specify the desired Docker image tags for each respective component. 
|
||||
|
||||
By leveraging the power of the Barge component, developers can accelerate their development workflows.\

Introducing Ocean.JS
|
||||
{% endembed %}
|
||||
|
||||
The Ocean.js library adopts the module architectural pattern, ensuring clear separation and organization of code units. Utilizing ES6 modules simplifies the process by allowing you to import only the necessary module for your specific task.
|
||||
|
||||
Our module structure follows this format:
|
||||
|
||||
* Types
|
||||
* Config
|
||||
* Contracts
|
||||
* Services
|
||||
* Utils
|
||||
|
||||
When working with a particular module, you will need to provide different parameters. To instantiate classes from the contracts module, you must pass objects such as Signer, which represents the wallet instance, or the contract address you wish to utilize, depending on the scenario. As for the services modules, you will need to provide the provider URI or metadata cache URI.

# Consume Asset
|
||||
|
||||
Consuming an asset involves a two-step process: placing an order and then utilizing the order transaction to download and access the asset's files. Let's delve into each step in more detail.
|
||||
|
||||
To initiate the ordering process, there are two scenarios depending on the pricing schema of the asset. Firstly, if the asset has a fixed rate pricing schema configured, you would need to acquire the corresponding datatoken by purchasing it. Once you have obtained the datatoken, you send it to the publisher to place the order for the asset.
|
||||
|
||||
The second scenario applies when the asset follows a free pricing schema. In this case, you can obtain a free datatoken from the dispenser service provided by Ocean Protocol. Using the acquired free datatoken, you can place the order for the desired asset.
|
||||
|
||||
However, it's crucial to note that even when utilizing free assets, network gas fees still apply. These fees cover the costs associated with executing transactions on the blockchain network.
|
||||
|
||||
Additionally, the specific type of datatoken associated with an asset influences the ordering process. There are two common datatoken templates: Template 1 (regular template) and Template 2 (enterprise template). The type of template determines the sequence of method calls required before placing an order.
|
||||
|
||||
For assets utilizing Template '1', prior to ordering, you need to perform two separate method calls. First, you need to call the `approve` method to grant permission for the fixedRateExchange contract to spend the required amount of datatokens. Then, you proceed to call the `buyDatatokens` method from the fixedRateExchange contract. This process ensures that you have the necessary datatokens in your possession to successfully place the order. Alternatively, if the asset follows a free pricing schema, you can employ the `dispenser.dispense` method to obtain the free datatoken before proceeding with the order.
|
||||
|
||||
On the other hand, assets utilizing Template '2' offer bundled methods for a more streamlined approach. For ordering such assets, you can use methods like `buyFromFreeAndOrder` or `buyFromDispenserAndOrder`. These bundled methods handle the acquisition of the necessary datatokens and the subsequent ordering process in a single step, simplifying the workflow for enterprise-template assets.
|
||||
|
||||
Later on, when working with the ocean.js library, you can use this order transaction identifier to call the `getDownloadUrl` method from the provider service class. This method allows you to retrieve the download URL for accessing the asset's files.

|
||||
6. **Asset unlisted**: Assets in the "Asset unlisted" state are not discoverable. However, users can still place orders for these assets, making them accessible. Unlisted assets are listed under the owner's profile, allowing users to view and access them.
|
||||
|
||||
By assigning specific states to assets, Ocean Protocol enables a structured approach to asset management and visibility. These states help regulate asset discoverability, ordering permissions, and the representation of assets in user profiles, ensuring a controlled and reliable asset ecosystem.
|
||||
|
||||
It is possible to remove assets from Ocean Protocol by modifying the state of the asset. Each asset has a state, which is stored in the NFT contract. Additional details regarding asset states can be found at this link: [https://docs.oceanprotocol.com/core-concepts/did-ddo#state](https://docs.oceanprotocol.com/core-concepts/did-ddo#state). There is also an assets purgatory that contains information about the purgatory status of an asset, as defined in the list-purgatory. For more information about the purgatory, please refer to: [https://docs.oceanprotocol.com/core-concepts/did-ddo#purgatory](https://docs.oceanprotocol.com/core-concepts/did-ddo#purgatory).
