Simple Rule Notification

Interpret some simples rules in json to generate notifications

About The Project

A way for persist some configurable rules for use in some data in frontend.

Usage

Install the package from npm:

npm i simple-rule-notification

Import the package:

const srn = require("simple-rule-notification");

Retrieve the following rules from backend:

const operacaoGrupo = {
    id: 1,
    acaoEnum: "CRIAR_REGISTRO_ATIVIDADE_NOTIFICACAO",
    operacaoRaiz: {
        id: 2,
        nomeCampo: "ocorrencia",
        comparadorEnum: "IGUAL",
        valor: "valor_esperado",
        proximaOperacao: null,
        operadorProximaOperacao: null,
    },
    tituloPadrao: "Ocorrência no Campo",
    mensagemPadrao: "O campo ocorrência foi preenchido.",
    tipoMensagem: "INFO",
    quantidadeDiasEntreDatasChave: null,
    respostasPadrao: null,
};

Then build a strategy and execute it, passing the data:

const data = {
    respostas: {
        ocorrencia: "valor_esperado",
    },
};
const applicableRule = srn.buildAcaoStrategy(operacaoGrupo, data).executar();

In this case the return will be:

{ "tipo": "CRIAR_REGISTRO_ATIVIDADE_NOTIFICACAO" }

If the entry has the following value:

const data = {
    respostas: {
        ocorrencia: "valor_nao_esperado",
    },
};

The return will be:

null;
