It works underneath Remix IDE "Solidity Compiler" plugin which is used to load different versions of compiler and compile the smart contracts. ### Installation `@remix-project/remix-solidity` is an NPM package and can be installed using NPM as: `yarn add @remix-project/remix-solidity` ### How to use `@remix-project/remix-solidity` exports: ``` { Compiler: Compiler, CompilerInput: CompilerInput } ``` `CompilerInput` can be used to form the [compiler input](https://github.com/remix-project-org/remix-project/blob/master/libs/remix-solidity/src/compiler/types.ts#L1) by passing the [options](https://github.com/remix-project-org/remix-project/blob/master/libs/remix-solidity/src/compiler/types.ts#L144) `Compiler` is a class containing various methods to perform compiler related actions. Have a look at `Compiler` interface: ``` class Compiler { handleImportCall: (fileurl: string, cb: Function) => void; event: EventManager; state: CompilerState; constructor(handleImportCall: (fileurl: string, cb: Function) => void); /** * @dev Setter function for CompilerState's properties (used by IDE) * @param key key * @param value value of key in CompilerState */ set(key: K, value: CompilerState[K]): void; /** * @dev Internal function to compile the contract after gathering imports * @param files source file * @param missingInputs missing import file path list */ internalCompile(files: Source, missingInputs?: string[]): void; /** * @dev Compile source files (used by IDE) * @param files source files * @param target target file name (This is passed as it is to IDE) */ compile(files: Source, target: string): void; /** * @dev Called when compiler is loaded, set current compiler version * @param version compiler version */ onCompilerLoaded(version: string): void; /** * @dev Called when compiler is loaded internally (without worker) */ onInternalCompilerLoaded(): void; /** * @dev Called when compilation is finished * @param data compilation result data * @param missingInputs missing imports * @param source Source */ onCompilationFinished(data: CompilationResult, missingInputs?: string[], source?: SourceWithTarget): void; /** * @dev Load compiler using given URL (used by IDE) * @param usingWorker if true, load compiler using worker * @param url URL to load compiler from */ loadVersion(usingWorker: boolean, url: string): void; /** * @dev Load compiler using 'script' element (without worker) * @param url URL to load compiler from */ loadInternal(url: string): void; /** * @dev Load compiler using web worker * @param url URL to load compiler from */ loadWorker(url: string): void; /** * @dev Gather imports for compilation * @param files file sources * @param importHints import file list * @param cb callback */ gatherImports(files: Source, importHints?: string[], cb?: gatherImportsCallbackInterface): void; /** * @dev Truncate version string * @param version version */ truncateVersion(version: string): string; /** * @dev Update ABI according to current compiler version * @param data Compilation result */ updateInterface(data: CompilationResult): CompilationResult; /** * @dev Get contract obj of the given contract name from last compilation result. * @param name contract name */ getContract(name: string): Record | null; /** * @dev Call the given callback for all the contracts from last compilation result * @param cb callback */ visitContracts(cb: visitContractsCallbackInterface): void | null; /** * @dev Get the compiled contracts data from last compilation result */ getContracts(): CompilationResult['contracts'] | null; /** * @dev Get sources from last compilation result */ getSources(): Source | null | undefined; /** * @dev Get sources of passed file name from last compilation result * @param fileName file name */ getSource(fileName: string): Source['filename'] | null; /** * @dev Get source name at passed index from last compilation result * @param index - index of the source */ getSourceName(index: number): string | null; } ``` ### Contribute Please feel free to open an issue or a pull request.
