node-red-contrib-filemaker

Node-RED FileMaker nodes. These nodes use fms-api-client to connect to FileMaker Server. Each node exposes an fms-api-client method or utility. Nodes connecting to FileMaker Server depend upon a configurable FileMaker Data API client.

Project Information

The nodes in this project use fms-api-client to connect via the FileMaker Data API to FileMaker Server. The nodes that connect to FileMaker Server depend upon a configurable client node. The client node uses marpat to store and maintain FileMaker Data API session information in-memory, on the filesystem, or in a MongoDB cluster. Persistence is configured via Node-RED's settings file. For more information see the storage section. For security client configuration parameters are not exported with a flow.

Once configured a client node will automatically create and maintain a FileMaker Data API session as needed. You are not required to call the login or logout nodes in a flow.

Each node can be configured to use either static or dynamic parameters. Dynamic parameters may be read from either the msg property or the flow and global contexts. The default output of each node is msg.payload. A node can also be configured to merge its output with any property on the msg object.

Installation

These nodes can be installed from the command line by running the following command in your Node-RED directory:

npm install --save node-red-contrib-filemaker

These nodes can also be installed using the Node-RED palette manager.

Storage

The nodes in this project all depend on a configurable Data API client. By default the client is saved in-memory. When saved in-memory a client will not persist between restarts of the Node-RED runtime. This means that each restart of the Node-RED runtime will cause the client to open new Data API sessions.

To persist a client between Node-RED runtime restarts and allow active session monitoring and maintenance additional datastores can be configured. This project will accept a url property and an options property from a marpat object in the Node-RED settings.js file. Any datastore made available by marpat. The url property accepts the following formats:

• MongoDB:
  • Format: mongodb://[username:password@]host[:port][/db-name]
• Filesystem:
  • Format: nedb://[directory-path]
• In Memory:
  • Format: nedb://memory

Stroage Configuration Example:

module.exports = {
  // the tcp port that the Node-RED web server is listening on
  uiPort: process.env.PORT || 1880,
  marpat: { url: process.env.DATASTORE, options: {} }

File ./red.dev.config.js

Status Node

The status node will return the current state of the configured client. The status node will return the client's data usage, urls for all pending and queued requests, and currently open sessions.

Status Illustration

Status Flow

Login Node

The login node will open a FileMaker Data API session. This node will also save the resulting session token for future use by the configured client. You are not required to login before using any other node in a flow.

Login Illustration

Login Flow

Logout Node

The logout node closes the currently open Data API session and removes the associated session token. You are not required to logout at the end of a flow.

Logout Illustration

Logout Flow

Product Info Node

The product info node gets server product info. This node gets metadata for the FileMaker server the client is configured to use.

Databases Node

The databases node gets all the scripts and script folders accesible to the client.

These nodes can be installed from the command line by running the following command in your Node-RED directory:

Create Node

The create node creates a record in FileMaker. By default The create node will use the value in msg.payload.layout as the layout context and msg.payload.data for setting field and portal data.

Edit Node

The edit node edits a specific record in FileMaker. By default the edit node will use msg.payload.recordId as the record id to target for editing, the data found in msg.payload.data for editing field and portal data, and msg.payload.layout as the layout context.

Edit Flow

Delete Node

The delete node deletes a specific record in FileMaker. By default the delete node will use msg.payload.recordId as the record id to target for deletion and msg.payload.layout as the layout context.

Transform Node

The tranform node transforms data in msg.payload.data. It reduces { table::field : value } properties to { table: { field : value } } properties.

Container Data Node

The container node retrieves container data from msg.payload.data. The container node requires a container property, a filename property, and a destination property. Each property should be a dot notation path to the required data, such as fieldData.container and fieldData.fileName. If the configured path does not exist it will be automatically created.
