\n\nREMME JavaScript Client\n==========\n[](https://www.npmjs.com/package/remme)\n\n**An open source JS integration library for REMChain, simplifying the access and interaction with REMME nodes both public or permissioned.**\n\n## How to use\n### 1. Install and run REMME node with required REST API methods enabled.\nYou can check out how to do that at [REMME core repo](https://github.com/Remmeauth/remme-core/).\n*Note: you can enable/disable methods by modifying **REMME_REST_API_AVAILABLE_METHODS** eviroment variable at the .env file.*\n\n### 2. Install the latest version of library to your JS project\n#### Node\n\n```bash\nnpm install remme\n```\n\n#### Yarn\n\n```bash\nyarn add remme\n```\n\n#### In the Browser\n\nUse the prebuild ``dist/remme.min.js``, or\nbuild using the [remme][repo] repository:\n\n```bash\nnpm run build\n```\n\nThen include `dist/remme.min.js` in your html file.\nThis will expose `Remme` on the window object.\n\n### 3. Run methods of **RemmeClient** class to interract with REMME node.\n\n### 4. Possible errors and solutions\n#### Can't find name \"Long\"\n**Describe**:\nOur library use protobuf.js to work with protobufs.\nSo for usage with Typescript you may get this error.
\n**Solution**:
\n1. You need to install @types/long.
\n2. You need to import Long before import remme library\n\n#### Can't resolve 'crypto' | Can't resolve 'stream'\n**Describe**:
\nOur library use crypto nodejs package for working with hash.\nSo for usage with Typescript you may get this error.
\n**Solution**:
\nhttps://github.com/ethereum/web3.js/issues/1555#issuecomment-388113909
\n1. open node_modules/@angular-devkit/build-angular/src/angular-cli-files/models/webpack-configs/browser.js\n2. Find \"node: false\", and change it to \"node: {crypto: true, stream: true}\"\n\n#### Failed to minify\n**Describe**:
\nOur library use sawtooth-sdk package.\nSo for usage with React you may get this error if you build app.
\n**Issue**: https://github.com/hyperledger/sawtooth-sdk-javascript/issues/4
\n**Solution**:
\n1. npm run eject\n2. npm i uglifyjs-webpack-plugin@1.3.0\n3.

\r\n\r\nREMME JavaScript Client\r\n==========\r\n[](https://www.npmjs.com/package/remme)\r\n\r\n**An open source JS integration library for REMChain, simplifying the access and interaction with REMME nodes both public or permissioned.**\r\n\r\n## How to use\r\n### 1. Install and run REMME node with required REST API methods enabled.\r\nYou can check out how to do that at [REMME core repo](https://github.com/Remmeauth/remme-core/).\r\n*Note: you can enable/disable methods by modifying **REMME_REST_API_AVAILABLE_METHODS** eviroment variable at the .env file.*\r\n\r\n### 2. Install the latest version of library to your JS project\r\n#### Node\r\n\r\n```bash\r\nnpm install remme\r\n```\r\n\r\n#### Yarn\r\n\r\n```bash\r\nyarn add remme\r\n```\r\n\r\n#### In the Browser\r\n\r\nUse the prebuild ``dist/remme.min.js``, or\r\nbuild using the [remme][repo] repository:\r\n\r\n```bash\r\nnpm run build\r\n```\r\n\r\nThen include `dist/remme.min.js` in your html file.\r\nThis will expose `Remme` on the window object.\r\n\r\n### 3. Run methods of **RemmeClient** class to interract with REMME node.\r\n\r\n### 4. Possible errors and solutions\r\n#### Can't find name \"Long\"\r\n**Describe**:\r\nOur library use protobuf.js to work with protobufs.\r\nSo for usage with Typescript you may get this error.
\r\n**Solution**:
\r\n1. You need to install @types/long.
\r\n2. You need to import Long before import remme library\r\n\r\n#### Can't resolve 'crypto' | Can't resolve 'stream'\r\n**Describe**:
\r\nOur library use crypto nodejs package for working with hash.\r\nSo for usage with Typescript you may get this error.
\r\n**Solution**:
\r\nhttps://github.com/ethereum/web3.js/issues/1555#issuecomment-388113909
\r\n1. open node_modules/@angular-devkit/build-angular/src/angular-cli-files/models/webpack-configs/browser.js\r\n2. Find \"node: false\", and change it to \"node: {crypto: true, stream: true}\"\r\n\r\n#### Failed to minify\r\n**Describe**:
\r\nOur library use sawtooth-sdk package.\r\nSo for usage with React you may get this error if you build app.
\r\n**Issue**: https://github.com/hyperledger/sawtooth-sdk-javascript/issues/4
