### Usage

**await solcjs(version)**

```js

const solcjs = require('solcjs-lightweight');

const version = 'v0.5.1-stable-2018.12.03';

let compiler = await solcjs(version);

// or

// let compiler = await solcjs();

const sourceCode = `

  pragma solidity >0.4.99 <0.6.0;

  library OldLibrary {

    function someFunction(uint8 a) public returns(bool);

  }

  contract NewContract {

    function f(uint8 a) public returns (bool) {

        return OldLibrary.someFunction(a);

    }

  }`;

let output = await compiler(sourceCode);

```

**await solcjs(version).version**

```js

const solcjs = require('solcjs-lightweight');

const version = 'v0.4.25-stable-2018.09.13';

let compiler = await solcjs(version);

console.dir(compiler.version);

// { name: 'v0.4.25-stable-2018.09.13',

// url: 'https://solc-bin.ethereum.org/bin/soljson-v0.4.25+commit.59dbf8f1.js' }

```

**await solcjs.versions()**

```js

const solcjs = require('solcjs-lightweight');

let select = await solcjs.versions();

const { releases, nightly, all } = select;

console.log(releases[0]);

// v0.4.25-stable-2018.09.13

```

**await solcjs.version2url(version)**

```js

const solcjs = require('solcjs-lightweight');

let version = 'v0.4.25-stable-2018.09.13';

let url = await solcjs.version2url(version);

console.log(url);

// https://solc-bin.ethereum.org/bin/soljson-v0.4.25+commit.59dbf8f1.js

```

```js

const solcjs = require('solcjs-lightweight');

let version = 'latest';

let url = await solcjs.version2url(version);

console.log(url);

// https://solc-bin.ethereum.org/bin/soljson-v0.1.1+commit.6ff4cd6.js

```

**await compiler(sourceCode);**

```js

const solcjs = require('solcjs-lightweight');

let compiler = await solcjs();

const sourceCode = `

  library OldLibrary {

      function someFunction(uint8 a) public returns(bool);

  }

  contract NewContract {

      function f(uint8 a) public returns (bool) {

          return OldLibrary.someFunction(a);

      }

  }`;

let output = await compiler(sourceCode);

```

**await compiler(sourceCode, getImportContent)**

```js

const solcjs = require('solcjs-lightweight');

const version = 'v0.5.1-stable-2018.12.03';

let compiler = await solcjs(version);

const sourceCode = `

  pragma solidity >0.4.99 <0.6.0;

    function someFunction(uint8 a) public returns(bool);

  }

  contract NewContract {

    function f(uint8 a) public returns (bool) {

        return OldLibrary.someFunction(a);

    }

  }`;

let myDB = new Map();

const ResolverEngine = require('solc-resolver').resolverEngine;

let resolverEngine = new ResolverEngine();

let resolveGithub = require('resolve-github');

const getImportContent = async function (path) {

  return myDB.has(path) ? myDB.get(path) : await resolverEngine.require(path);

};
