[pulkit-30]

fix: #216

Description

Minimize promise chaining in asynchronous functions. replaced .then with “async - await” wherever possible.

Changes

Example changes in src/components/Footer/index.jsx file:

Before

  const fetchVersion = () => {
    return getFossologyVersion()
      .then((res) => {
        setSessionStorage("fossologyVersion", res);
        setVersion(res);
        return res;
      })
      .catch(() => null);
};

After

 const fetchVersion = async () => {
    try {
      const res = await getFossologyVersion();
      setSessionStorage("fossologyVersion", res);
      setVersion(res);
      return res;
    } catch (error) {
      return null;
    }
  };
