Apollo is a JavaScript library to get real-time economic declarations such as inflation rates, unemployment rates or interest rates reported by governments or other entities.

This library gives its best when used with Mida, the JavaScript framework to operate in global financial markets which can be used with Apollo to create expert advisors and perform market analysis based on macroeconomic data.

First you have to choose an economic factor and then request its declarations

const { ApolloEconomicFactor } = require("@reiryoku/apollo");

const japanInflationRate = ApolloEconomicFactor.getById("Japan/CPI/YoY");
const lastDeclaration = await japanInflationRate.getLastDeclaration();

console.log(`Japan inflation rate is ${lastDeclaration.actualValue}%`);
console.log(`The last declaration was made on ${lastDeclaration.date}`);

export type ApolloEconomicFactorDeclaration = {
    date: Date;
    previousDeclaration?: ApolloEconomicFactorDeclaration;
    nextDeclaration?: ApolloEconomicFactorDeclaration;
    actualValue?: number;
    forecastValue?: number;
};
