将 json-schema-faker 架构合并到一个文件中

Question

我正在使用 faker 生成多个模式，并希望将解析的结果合并到一个名为 ./db.json 的文件中，而不是多个文件中，这样我就可以在 json-server 中使用该文件。

我当前将其设置为根据架构文件夹中的架构数量运行和打印多个文件。

const path = require("path");
const fs = require("fs");
const { resolve, extend } = require("json-schema-faker");

extend("faker", () => require("@faker-js/faker"));

var schemasPath = path.join(__dirname, "./schemas");

fs.readdirSync(schemasPath).forEach((file) => {
  const name = path.parse(file).name;
  const schemas = require(`${schemasPath}/${file}`);
  resolve(schemas).then((data) => {
    fs.writeFile(`${__dirname}/${name}.json`, JSON.stringify(data), (err) => {
      if (err) {
        console.log("error = ", err.message);
      } else {
        console.log("Mock API data generated.");
      }
    });
  });
});

架构示例：

const schema = {
  type: "object",
  properties: {
    users: {
      type: "array",
      minItems: 10,
      maxItems: 10,
      uniqueItems: true,
      items: {
        type: "object",
        properties: {
          id: {
            type: "integer",
            initialOffset: 1,
            autoIncrement: true,
          },
          name: {
            type: "string",
            faker: "name.findName",
          },
        },
        required: ["id", "name"],
      },
    },
  },
  required: ["users"],
};

对于可能遇到这篇文章的其他人来说，这里是我最终解决它的方法。

const lodash = require("lodash");
const path = require("path");
const fs = require("fs");
const { faker } = require("@faker-js/faker");
const { resolve, extend } = require("json-schema-faker");

extend("faker", () => faker);

var schemaFolder = path.join(__dirname, "./schemas");
var schemas = [];

fs.readdirSync(schemaFolder).forEach((file) => {
  const schema = require(`${schemaFolder}/${file}`);
  schemas.push(schema);
});

const promises = schemas.map((file) => resolve(file));
Promise.all(promises)
  .then((data) => {
    const result = data.reduce((acc, curr) => {
      const key = Object.keys(curr);
      acc[key] = curr[key];
      return acc;
    }, {});
    writeToFile(result);
  })
  .catch((error) => console.log("error = ", error));

const writeToFile = (data) => {
  fs.writeFile(`${__dirname}/db.json`, JSON.stringify(data), (err) => {
    if (err) {
      console.log("error = ", err.message);
    } else {
      console.log("Mock data generated to file ./db.json");
    }
  });
};
