    Documentation | Bugs | Chat

    Installation

    npm i @nano-sql/adapter-dynamo --save

    Usage

    import { DynamoDB } from "@nano-sql/adapter-dynamo";
    import { nSQL } from "@nano-sql/core";
     
    nSQL().connect({
        id: "my_db",
        mode: new DynamoDB(),
        tables: [...]
    }).then(...)

    API

    The DynamoDB class accepts two optional arguments in it's constructor.

    AWS Dynamo DB Options

    The first object is passed directly into the aws-sdk constructor for AWS.DynamodDB, allowing you to adjust connect preferences and other things. The constructor properties are documented by AWS here.

    Query Filter Object

    Each key is an optional function that allows you to adjust the different queries being sent from this adapter to AWS.

    Types are imported with import * as AWS from "aws-sdk";

    Key DynamoDB Query Type
    filterSchema createTable AWS.DynamoDB.CreateTableInput
    filterDrop deleteTable AWS.DynamoDB.DeleteTableInput
    filterScan scan AWS.DynamoDB.DocumentClient.ScanInput
    filterQuery query AWS.DynamoDB.DocumentClient.QueryInput
    filterUpdate update AWS.DynamoDB.DocumentClient.UpdateItemInput
    filterDelete delete AWS.DynamoDB.DocumentClient.DeleteItemInput
    filterGet get AWS.DynamoDB.DocumentClient.GetItemInput
    import { DynamoDB } from "@nano-sql/adapter-dynamo";
    import { nSQL } from "@nano-sql/core";
    import * as AWS from "aws-sdk";
     
    // example filter for schema
    nSQL().connect({
        id: "my_db",
        mode: new DynamoDB({}, {
            filterSchema: (schemaArgs: AWS.DynamoDB.CreateTableInput) => {
                // mess with schema args
                return schemaArgs;
            }
        }),
        tables: [...]
    }).then(...)

    Limitations

    Full table scans or using offset/limit, especially with reverse order will work but cause you to have a bad time.

    Focus on using IN, =, or BETWEEN with primary keys and secondary indexes, even with reverse order these are fine.
