Can be used to construct, sign and broadcast transactions in JavaScript, and to easily obtain data from the blockchain via public apis.\n\nMost of this code was written by [jcalfee](https://github.com/jcalfee), my work was mostly just repackaging to a discrete npm package.\n\n[![npm version](https://img.shields.io/npm/v/bitsharesjs.svg?style=flat-square)](https://www.npmjs.com/package/bitsharesjs)\n[![npm downloads](https://img.shields.io/npm/dm/bitsharesjs.svg?style=flat-square)](https://www.npmjs.com/package/bitsharesjs)\n\n\n## Setup\n\nThis library can be obtained through npm:\n```\nnpm install bitsharesjs\n```\n\n## Usage\n\nThree sub-libraries are included: `ECC`, `Chain` and `Serializer`. Generally only the `ECC` and `Chain` libraries need to be used directly.\n\n### Chain\nThis library provides utility functions to handle blockchain state as well as a login class that can be used for simple login functionality using a specific key seed.\n\n#### Login\nThe login class uses the following format for keys:\n\n```\nkeySeed = accountName + role + password\n```\n\nUsing this seed, private keys are generated for either the default roles `active, owner, memo`, or as specified. A minimum password length of 12 characters is enforced, but an even longer password is recommended. Three methods are provided:\n\n```\ngenerateKeys(account, password, [roles])\ncheckKeys(account, password, auths)\nsignTransaction(tr)\n```\n\nThe auths object should contain the auth arrays from the account object. An example is this:\n\n```\n{\n active: [\n [\"GPH5Abm5dCdy3hJ1C5ckXkqUH2Me7dXqi9Y7yjn9ACaiSJ9h8r8mL\", 1]\n ]\n}\n```\n\nIf checkKeys is successful, you can use signTransaction to sign a TransactionBuilder transaction using the private keys for that account.\n\n#### State container\nThe Chain library contains a complete state container called the ChainStore. The ChainStore will automatically configure the `set_subscribe_callback` and handle any incoming state changes appropriately. It uses Immutable.js for storing the state, so all objects are return as immutable objects. It has its own `subscribe` method that can be used to register a callback that will be called whenever a state change happens.\n\nThe ChainStore has several useful methods to retrieve, among other things, objects, assets and accounts using either object ids or asset/account names. These methods are synchronous and will return `undefined` to indicate fetching in progress, and `null` to indicate that the object does not exist.\n\n```\nimport {Apis} from \"bitsharesjs-ws\";\nvar {ChainStore} = require(\"bitsharesjs\");\n\nApis.instance(\"wss://eu.nodes.bitshares.ws\", true).init_promise.then((res) => {\n console.log(\"connected to:\", res[0].network);\n ChainStore.init().then(() => {\n ChainStore.subscribe(updateState);\n });\n});\n\nlet dynamicGlobal = null;\nfunction updateState(object) {\n dynamicGlobal = ChainStore.getObject(\"2.1.0\");\n console.log(\"ChainStore object update\\n\", dynamicGlobal ? dynamicGlobal.toJS() : dynamicGlobal);\n}\n\n```\n\n### ECC\nThe ECC library contains all the crypto functions for private and public keys as well as transaction creation/signing.\n\n#### Private keys\nAs a quick example, here's how to generate a new private key from a seed (a brainkey for example):\n\n```\nvar {PrivateKey, key} = require(\"bitsharesjs\");\n\nlet seed = \"THIS IS A TERRIBLE BRAINKEY SEED WORD SEQUENCE\";\nlet pkey = PrivateKey.fromSeed( key.normalize_brainKey(seed) );\n\nconsole.log(\"\\nPrivate key:\", pkey.toWif());\nconsole.log(\"Public key :\", pkey.toPublicKey().toString(), \"\\n\");\n```\n\n#### Transactions\nTODO transaction signing example\n\n## ESDoc (beta)\n```bash\nnpm i -g esdoc esdoc-es7-plugin\nesdoc -c ./esdoc.json\nopen out/esdoc/index.html\n```\n", "longname": "/home/sigve/Dev/Bitshares/bitsharesjs/README.md", "name": "./README.md", "static": true, "access": "public" }, { "kind": "packageJSON", "content": "{\n \"name\": \"bitsharesjs\",\n \"version\": \"1.7.5\",\n \"description\": \"Pure JavaScript Bitshares library for node.js and browsers.\",\n \"browser\": {\n \"ws\": false,\n \"crypto\": false\n },\n \"scripts\": {\n \"test\": \"cross-env BABEL_ENV=test mocha --compilers js:babel-register --recursive\",\n \"test:chain\": \"cross-env BABEL_ENV=test mocha --compilers js:babel-register ./test/chain --recursive --watch\",\n \"test:trxbuilder\": \"cross-env BABEL_ENV=test mocha --compilers js:babel-register ./test/chain/TransactionBuilder.js --watch\",\n \"test:ecc\": \"cross-env BABEL_ENV=test mocha --compilers js:babel-register ./test/ecc --recursive\",\n \"test:serializer\": \"cross-env BABEL_ENV=test mocha --compilers js:babel-register ./test/serializer --recursive\",\n \"test:watch\": \"npm test -- --watch\",\n \"clean\": \"rimraf dist build es\",\n \"prebuild\": \"npm run clean\",\n \"build\": \"cross-env BABEL_ENV=cjs babel lib -d dist\",\n \"build-es\": \"cross-env BABEL_ENV=es babel lib -d es\",\n \"postbuild\": \"npm run browserify && npm run build-es\",\n \"build:watch\": \"babel lib -d dist --watch\",\n \"prebrowserify\": \"mkdirp build\",\n \"browserify\": \"cross-env NODE_ENV=production browserify --full-paths dist/browser.js --standalone bitshares_js -o build/bitsharesjs.js -d\",\n \"postbrowserify\": \"cross-env NODE_ENV=production uglifyjs --compress --mangle --sequences --drop_console --output build/bitsharesjs.min.js -- build/bitsharesjs.js\",\n \"precommit\": \"npm run doc && git add docs && pretty-quick --staged && npm run test\",\n \"prepublish\": \"npm run build && npm run test\",\n \"doc\": \"esdoc -c esdoc.json\",\n \"example:transfer\": \"babel-node examples/transfer\",\n \"example:chainStore\": \"babel-node examples/chainStore\",\n \"example:privKey\": \"babel-node examples/privKey\"\n },\n \"repository\": {\n \"type\": \"git\",\n \"url\": \"git+https://github.com/bitshares/bitsharesjs.git\"\n },\n \"author\": \"Sigve Kvalsvik (https://github.com/svk31)\",\n \"contributors\": [\n \"James Calfee (https://github.com/jcalfee/)\",\n \"Daniel Larimer (https://github.com/bytemaster/)\",\n \"Valentine Zavgorodnev (https://github.com/valzav/)\"\n ],\n \"license\": \"MIT\",\n \"bugs\": {\n \"url\": \"https://github.com/bitshares/bitsharesjs/issues\"\n },\n \"engines\": {\n \"node\": \">= 6.0.0\"\n },\n \"main\": \"./dist/index.js\",\n \"jsnext:main\": \"./es/index.js\",\n \"dependencies\": {\n \"bigi\": \"1.4.2\",\n \"bitsharesjs-ws\": \"^1.5.2\",\n \"bs58\": \"4.0.1\",\n \"bytebuffer\": \"5.0.1\",\n \"create-hash\": \"1.2.0\",\n \"create-hmac\": \"1.1.7\",\n \"crypto-js\": \"3.1.9-1\",\n \"deep-equal\": \"1.0.1\",\n \"ecurve\": \"1.0.6\",\n \"event-emitter\": \"0.3.5\",\n \"immutable\": \"3.8.2\",\n \"safe-buffer\": \"^5.1.2\",\n \"secure-random\": \"1.1.1\"\n },\n \"devDependencies\": {\n \"assert\": \"^1.4.1\",\n \"babel-cli\": \"^6.26.0\",\n \"babel-eslint\": \"^8.2.3\",\n \"babel-plugin-add-module-exports\": \"^0.2.1\",\n \"babel-preset-env\": \"^1.7.0\",\n \"babel-preset-stage-1\": \"^6.24.1\",\n \"browserify\": \"^16.2.2\",\n \"cross-env\": \"^5.0.1\",\n \"esdoc\": \"^1.1.0\",\n \"esdoc-standard-plugin\": \"^1.0.0\",\n \"eslint\": \"^4.19.1\",\n \"husky\": \"^0.14.3\",\n \"mkdirp\": \"^0.5.1\",\n \"mocha\": \"^5.2.0\",\n \"prettier\": \"^1.11.1\",\n \"pretty-quick\": \"^1.4.1\",\n \"rimraf\": \"^2.6.1\",\n \"uglify-js\": \"^3.3.10\"\n }\n}\n", "longname": "/home/sigve/Dev/Bitshares/bitsharesjs/package.json", "name": "package.json", "static": true, "access": "public" } ]
