Fluree: Beyond the Database

Build better applications with a tamper-proof blockchain ledger, semantic graph query engine, linearly scalable query edge servers, and co-resident data security

Extension

Welcome to the Fluree VS Code extension. This extension connects to a single Fluree database, and allows you to issue queries, transaction, and tests against that database.

Please note this is a beta version of the Fluree extension. Any issues and feature ideas can be sent to support@flur.ee. You can also join our Slack channel.

The is extension version 0.11.0, which is targeted to Fluree release 0.11.0.

Connecting to a Database

To connect to a database, you must have a Fluree database running. You can either use a config file or manually specify your configuration details.

Config File

If you want to use a config file, create a flureeConfig.json file in the parent directory for your project. This file should include a single map with the following key-value pairs.

{
    "network": "example",
    "db": "one",
    "ip": "http://localhost:8090"
}

Once you create this file, you will need to run the command: Fluree: Set Config see below.

Set Config

To connect to a database, you will need to run the command Fluree: Set Config.

To view the Command Palette, you can click on View -> Command Palette. On Mac, the shortcut to open the Command Palette is cmd + shift + p.

If you have a valid flureeConfig.json file, this configuration will be set based on what is included in that file.

If you do not, you will be asked to input your database's ip, network, and db.

Get Config

You can run the command, Fluree: Get Config to view the current configuration.

Query

To issue a query, simply select a valid query with your cursor, and run the command, Fluree: Query. The results of the query will display in the file flureeResponse.txt.

Note that the contents of flureeResponse.txt will be overwritten every time you issue a query or command. If you need to persist the results of a given query or transaction, please copy it into another file.

We only support issuing queries in FlureeQL.

Gen Flakes

To issue gen-flakes, simply select a valid transaction with your cursor, and run the command, Fluree: Gen-Flakes. The results will display in the file flureeResponse.txt.

Gen-flakes returns the list of flakes that would be added to a ledger if a given transaction is issued. The body of this request is simply the transaction. Note that this is a test endpoint. This does NOT write the returned flakes to the ledger.

Note: this will only work with Fluree 0.11.0 and higher.

Query With

To issue query-with, simply select a valid query-with statement (a map with query and flakes keys) with your cursor, and run the command, Fluree: Query-With. The results will display in the file flureeResponse.txt.

Gen-flakes returns the list of flakes that would be added to a ledger if a given transaction is issued. The body of this request is simply the transaction. Note that this is a test endpoint. This does NOT write the returned flakes to the ledger.

Query-with returns the results of a query using the existing database flakes, including flakes that are provided with the query.

The request expects a map with two key-value pairs:

• flakes: An array of valid flakes
• query: A query to issue against the current database plus the flakes in the flakes value.

The t on the flakes provided has to be current with the latest database. For example, if you used gen-flakes, but then issued a transaction, you will need to use gen-flakes again to generate new valid flakes.

Note: this will only work with Fluree 0.11.0 and higher.

Test Transact With

To issue test-transact-with, simply select a valid test-transact-with statement (a map with tx and flakes keys) with your cursor, and run the command, Fluree: Test-Transact-With. The results will display in the file flureeResponse.txt.

Given a valid set of flakes that could be added to the database at a given point in time and a transaction, test-transact-with returns the flakes that would be added to a ledger if a given transaction is issued.

The request expects a map with the following key-value pairs:

• flakes: An array of valid flakes
• txn: A transaction to issue against the current database plus the flakes in the flakes value. This endpoint does NOT actually write the transaction to the ledger.
• auth: (Optional) The _auth/id with which to issue the transaction.

The t on the flakes provided has to be current with the latest database. For example, if you used gen-flakes, but then issued a transaction, you will need to use gen-flakes again to generate new valid flakes.

Note: this will only work with Fluree 0.11.0 and higher.

Transact

To issue a transaction, simply select a valid transaction with your cursor, and run the command, Fluree: Transact. The results of the query will display in the file flureeResponse.txt. Transactions are submitted using the root auth in the database. There is no way to change this currently.

Note that the contents of flureeResponse.txt will be overwritten every time you issue a query or command. If you need to persist the results of a given query or transaction, please copy it into another file.

Smart Function Help

Issue the command, Fluree: Smart Function Help to see a list of all the smart functions in FlureeDB, as well as arguments, examples, and documentation.
