Introduction

A FileMaker Data API client for NodeJS

easy-fm is a Node.js module that allows you to interact with a FileMaker database stored on a FileMaker server or FileMaker Cloud. This module interacts with your server using the FileMaker Data API.

Installation

npm install @jd-data-limited/easy-fm --save

easy-fm also requires the following to be configured within your FileMaker enviroment:

1. Enable the FileMaker Data API from the server's admin console. This setting is located in Connectors > FileMaker Data API.
2. Create a FileMaker database account for easy-fm to use. This account must have the 'Access via FileMaker Data API ( fmrest)' extended privilege

Usage

Connecting to a database

import FMHost from "easy-fm"; // Import the module
const host = new FMHost("https://<your-servers-address>")
const database = host.database({
    database: "your_database.fmp12",
    credentials: {
        method: "filemaker",
        username: "<username>",
        password: "<password>"
    },
    externalSources: []
})

// OPTIONAL - EasyFM will automatically attempt a login anyway when you perform your first operation
database.login().then(() => {

})

NOTE: A connection will only give you access to the layouts in the database you are connected to, and not the layouts in any external sources that you have specified.

If you need to interact with layouts on multiple databases, you need to open a separate connection for each.

An important note about timezones

Although it is recommended, timestamps in FileMaker databases are not always stored in UTC time. To account for this, EasyFM allows you to specify a function/method that determines the server's current timezone. EasyFM will use this timezone offset to convert timestamps to and from JavaScript Date objects.

import FMHost from "easy-fm";
import {type Moment} from 'moment'

const host = new FMHost("https://<your-servers-address>", (moment: Moment) => {

})

Getting records

One of (if not the) most common interactions you'll need to use is fetching records.

Fetch a range of records

let layout = database.getLayout("Your layout name")
let query = layout.records.list({
    portals: {
        test: {limit: 10, offset: 1} // Include results from the 'test' portal
    },
    limit: 10, // Limit result set to 10 records...
    offset: 30 // ...starting from the 30th record
})

let records = await query.fetch()
console.log(records)

Searching for records

Searching for records uses the same syntax as above, but with additional steps to add your search parameters.

let layout = database.getLayout("Your layout name")
let query = layout.records.list({
    portals: {
        test: {limit: 10, offset: 1} // Include results from the 'test' portal
    },
    limit: 10, // Limit result set to 10 records...
    offset: 30 // ...starting from the 30th record
})

query.addRequest({"GroupID": "=abc"}) // Add a filter

let records = await query.fetch()
console.log(records)

Fetch a record using its record ID (NOT RECOMMENDED)

Please note: When in FileMaker Pro, a record's ID is returned when using Get(RecordID). If you need to fetch a record using a different ID, use the search method above.

let layout = database.getLayout("Your layout name")
let record = await layout.records.get(164)
console.log(record)

Create a record

let layout = database.getLayout("Your layout name")
let record = await layout.records.create()

record.fields["Field1"].value = "Value here"
record.fields["Field2"].value = "Value here"
record.fields["Field3"].value = "Value here"

await record.commit()

Modify a record

let layout = database.getLayout("Your layout name")
let record = await layout.records.get(164)

record.fields["Field1"].value = "Value here"
record.fields["Field2"].value = "Value here"
record.fields["Field3"].value = "Value here"

await record.commit()

Field names

When interacting with FileMaker, it is important to remember how FileMaker field names work.

Field name format	Use when....
FieldName	Use this when the field you are accessing is in the same table that the layout has been assigned to
RelatedTableName::FieldName	Use this when the field is not in the same table that the layout has been assigned to

NOTE: You will not be able to access any fields that are not on the layout.

Portal names

Please read this section carefully if you are working with portals

It is important to note that a portal's name is not the same as the name of the table that it links to. The name of a portal matches the object name it was assigned in FileMaker's layout editor.

NOTE: When no name has been manually assigned to it, it will default to the name of the related table.

Typescript Implementation

easy-fm supports the use of TypeScript. Here's an example of how this works with easy-fm:

import FMHost, {Portal, Field, Container} from "@jd-data-limited/easy-fm";

interface UsersLayout {
    fields: {
        // Map each field on the layout to a field type.
        first_name: Field<string>
        age: Field<number>
        birthdate: Field<Date>
        profile_picture: Field<Container>
        "MyRelatedTable::MyRelatedField": Field<string>
    },
    portals: {
        Files: {
            "Files::Field1": Field<string>
        }
    }
}

interface DatabaseStructure {
    layouts: {
        users: UsersLayout
    }
}

const host = new FMHost("https://example_filemaker_server.com")
const database = host.database<DatabaseStructure>({
    database: "ExampleDatabase.fmp12",
    credentials: {method: "filemaker", username: "test", passsword: "test"},
    externalSources: []
})
await database.login()

const layout = database.getLayout("users") // The UsersLayout interface will be automatically applied to all records within this layout
const record = await layout.records.create()
record.fields["first_name"].value = "Joe"
record.fields["age"].value = 38
